Vegetation - Great Valley Tile [ds3231]
type: Dataset
description: Geodatabase feature class containing a map tile of vegetation within the Great Valley Ecoregion. The vegetation tile combines these datasets: Great Valley Ecoregion [ds2632], Central Valley Flood Protection Planning Area Update - 2016 [ds2890], Delta Vegetation and Land Use Update - 2016 [ds2855], Suisun Marsh 2024 [ds3221]. In areas where these datasets overlapped an erase tool was used to ensure the most up to date dataset is displayed. Great Valley Ecoregion [ds2632] The Great Valley Ecoregion vegetation polygons were manually digitized as interpreted using the National Agricultural Inventory Program's (NAIP) 2009 (Central Valley Riparian and Sacramento Valley map), 2012 (Southern San Joaquin Valley map) and 2014 (balance of San Joaquin Valley) aerial imagery at a scale of 1:2000. The minimum mapping unit (mmu) for natural vegetation is 1.0 acre, with a minimum average width of 10 meters. The mmu for agricultural and urban polygons is 10 acres. Vegetation is attributed to the Group and Alliance level of the state and national vegetation hierarchy. In some cases, polygons were attributed only to Group or Macrogroup level when the Alliance could not be determined from photointerpretation. The map classification is based on the key to vegetation types in Buck-Diaz et al. 2012. The Central Valley and Sacramento Valley maps were assessed for Accuracy with an average users’ accuracy of 90.2% and users’ accuracy of 89%. The San Joaquin Valley portion of the map was field verified by the mappers but was not otherwise assessed for accuracy (see Supplemental Information below for details). Suisun Marsh 2024 [ds3221] To create the 2024 Suisun Marsh vegetation map, vegetation was interpreted from a mosaic of the true color imagery that was flown in June 2024. Polygons were delineated using heads-up digitizing (i.e., a photo interpreter manually drew polygons around each stand of vegetation) in Esri's ArcGIS Pro 3.4.3, and polygon attributes were recorded within a file geodat…

Power Outage Incidents
type: Dataset
description: The power outages in this layer are pulled directly from the utility public power outage maps and is automatically updated every 15 minutes. This dataset represents only the most recent power outages and does not contain any historical data. The following utility companies are included: Pacific Gas and Electric (PG&E) Southern California Edison (SCE) San Diego Gas and Electric (SDG&E) Sacramento Municipal Utility District (SMUD) Layers included in this dataset: Power Outage Incidents - Point layer that shows data from all of the utilities and is best for showing a general location of the outage and driving any numbers in dashboards. Power Outage Areas - Polygon layer that shows rough power outage areas from PG&E only (They are the only company that feeds this out publicly). With in the PG&E territory this layer is useful to show the general area out of power. The accuracy is limited by how the areas are drawn, but is it good for a visual of the impacted area. Power Outages by County - This layer summaries the total impacted customers by county. This layer is good for showing where outages are on a statewide scale.

2025 Draft Updates of Data for CEC Busbar Mapping Assessment (2026-2027 IRP Cycle)
type: Dataset
description: During the August 19, 2025 Modeling Advisory Group webinar as part of the CPUC’s Assumptions for the 2026-2027 TPP, CEC staff proposed a number of updates to the data used in CEC's environmental and land use evaluation for Busbar Mapping. Many of the data updates were transitioning to the latest available data versions of individual datasets that are compiled into the CEC Land Use Screens. These changes can be described in three categories: Updated data versions of components used to define higher implication land1 : High Landscape Intactness Critical Habitat CEC Cropland Index Model High Category Updated Protected Area Layer within California to consolidate datasets and to rely on the most recently available data. Expansion of the CEC Protected Area Layer to CAISO areas that are electrically within California but physically within southern Nevada and Western Arizona. More information is found in the CEC presentation from the August 19 webinar, as well as the 2023 Land Use Screens Staff Report in the CEC Energy Planning Library. 1. For more information on lower and higher implication land, especially in the context of IRP busbar mapping, see previous definitions and usages from past workshops, including the recent webinar slides.

CA Urban Retail Water System Water Loss Annual Loss Audit Data
type: Dataset
description: This dataset contains annual validated water loss audit reports submitted to the Department of Water Resources by California urban retail water suppliers, as required under Title 23, California Code of Regulations Section 638.5(c) (Regulation). California Water Code Section 10608.12(af) specifies that urban retail water suppliers are those water suppliers directly providing potable municipal water to more than 3,000 service connections or that supply more than 3,000 acre-feet per year at retail for municipal purposes. The Regulation mandates that urban retail water suppliers with multiple separate potable water systems submit a separate audit for each system, regardless of system size. The dataset includes individual water loss audits for all potable water systems owned by urban retail water suppliers, including reports from water suppliers newly classified as urban retail water suppliers. While all submissions are available at the WUEdata.ca.gov portal, this dataset provides a cleaned version with only the latest submissions (older submissions that were corrected are not included). Water system boundaries for the water system water loss data in this dataset may be available in the Water Board's DDW California Drinking Water System Area Boundaries (SABL) tool. The link to this tool can be found in Additional Resources as part of this dataset. Water loss audits evaluate real water losses (leaks) and apparent water losses (e.g. data errors, water theft) occurring in a potable water distribution system. Estimating the scale and cost of these losses allows utilities to identify opportunities for saving water and recovering revenue. California water loss audit submissions were reviewed by validators and submitted to DWR starting in 2016. The reviews followed the validation methodology detailed in Water Research Foundation Project 4639: Level 1 Water Audit Validation. Level 1 water audit validation aims to: * Identify and, where possible, correct inaccuracies in water aud…

Surface Water - Chemistry Results
type: Dataset
description: This data provides results from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN) for field and lab chemistry analyses. The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering. **NOTE:** Some of the field and lab chemistry data that has been submitted to CEDEN since 2020 has not been loaded into the CEDEN database. That data is not included in this data set (and is also not available via the CEDEN query tool described above), but is available as a supplemental data set available here: **[Surface Water - Chemistry Results - CEDEN Augmentation](https://data.ca.gov/dataset/surface-water-chemistry-results-ceden-augmentation)**. For consistency, many of the conditions applied to the data in this dataset and in the CEDEN query tool are also applied to that supplemental dataset (e.g., no rejected data or replicates are included), but that supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data available here.

Current Employment Statistics (CES)
type: Dataset
description: The Current Employment Statistics (CES) program is a Federal-State cooperative effort in which monthly surveys are conducted to provide estimates of employment, hours, and earnings based on payroll records of business establishments. The CES survey is based on approximately 119,000 businesses and government agencies representing approximately 629,000 individual worksites throughout the United States. CES data reflect the number of nonfarm, payroll jobs. It includes the total number of persons on establishment payrolls, employed full- or part-time, who received pay (whether they worked or not) for any part of the pay period that includes the 12th day of the month. Temporary and intermittent employees are included, as are any employees who are on paid sick leave or on paid holiday. Persons on the payroll of more than one establishment are counted in each establishment. CES data excludes proprietors, self-employed, unpaid family or volunteer workers, farm workers, and household workers. Government employment covers only civilian employees; it excludes uniformed members of the armed services. The Bureau of Labor Statistics (BLS) of the U.S. Department of Labor is responsible for the concepts, definitions, technical procedures, validation, and publication of the estimates that State workforce agencies prepare under agreement with BLS.

Surface Water - Aquatic Organism Tissue Sample Results
type: Dataset
description: This data set provides results of tissue from organisms found in surface waters, from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN). The data are of tissue from individual organisms and of composite samples where tissue samples from multiple organisms are combined and then analyzed. Both the individual samples and the composite sample results may be given so for individual samples, there will be a row for the individual sample and a row for the composite where the number per composite is one. The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering.

GSP Monitoring Data
type: Dataset
description: The Groundwater Sustainability Plan (GSP) Monitoring dataset contains the monitoring sites and associated groundwater level, subsidence or streamflow measurements collected by Groundwater Sustainability Agencies (GSA) during implementation of their GSP. All data is submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). The GSP Regulations established the monitoring network criteria (23 CCR § 354.34) and the data and reporting standard for monitoring sites and measurements (23 CCR § 352.4). The data fields associated with these datasets were created by DWR to ensure that GSAs electronically submit monitoring site and measurement data which meets the GSP Regulation’s data and reporting standards. For additional information regarding GSAs, GSPs, and SGMA related monitoring, please view DWR’s SGMA Portal Resources at https://sgma.water.ca.gov/portal/.

COVID-19 Sewershed Restricted Case Data
type: Dataset
description: The California Department of Public Health (CDPH) aggregates confirmed cases of COVID-19 by sewershed restricted locations. Confirmed cases are defined as individuals with a positive molecular test, which tests for viral genetic material, such as a polymerase chain reaction test. Since wastewater data available starts from January 1st, 2021, rather than the beginning of the COVID-19 pandemic in 2020, the cumulative counts of the confirmed cases variable are shown as “NA”. Please note that values less than 5 for confirmed cases are masked (shown as “Masked”) if the sewershed population size is 50,000 or fewer, in accordance with de-identification guidelines. Values less than 3 for cases are masked (shown as “Masked”) if the sewershed population size is between 50,001 and 250,000. For no confirmed cases reported, values are set as zero.

Dry Well Reporting System Data
type: Dataset
description: In California, water systems serving one (1) to 15 households are regulated at the county level. Counties vary in their practices, but rarely do counties collect data regularly from these systems. Even where data is collected, it is entirely voluntary. A review of well permit information suggests there are over 1 million such water systems in California. In early 2014, a cross-agency Work Group created an easily accessible reporting system to get more systematic data on which parts of the state had households at risk of water supply shortages. The initial motivation for local water supply systems to report shortage information was to obtain statewide drought assistance. The reporting system receives ongoing reports of shortages from local, state, federal and non-governmental organizations, and tracks their status to resolution. While several counties have developed their own tracking mechanisms, this data is manually entered into the reporting system. The cross-agency team, led by DWR, seeks to verify and update the data submitted. However, due to the volunteer nature of the reporting and limitations on reporting agencies, collected data are undoubtedly under-representative of all shortages to have occurred. In addition, reports are received from multiple sources and there are occasionally errors and omissions that can create duplicate entries, non-household water supply reporting, and under-reporting. For example, missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county, rather only that none have been reported to the State.

State Water Project Routine Water Quality Monitoring
type: Dataset
description: The California State Water Project (SWP) is one of the nation’s largest water conveyance projects. Its geographic extent stretches from Sierra Nevada lakes north of Lake Tahoe, down the Central Valley, across several mountain ranges, and through the Mojave Desert, ultimately terminating at four large reservoirs in Southern California. The SWP also supplies water to communities in the northern and southern San Francisco Bay Area and along the Central Coast. In total, the SWP delivers raw drinking water to treatment plants serving over 27 million people, provides irrigation water for more than 750,000 acres of farmland, and supports recreational access at many lakes and reservoirs throughout the state. The Division of Operations and Maintenance within the Department of Water Resources (DWR) monitors water quality in the SWP at locations strategically situated throughout the Project. The SWP monitoring program began in the early 1960s and continues to this day. The location, frequency, and constituents tested for have changed several times during this period to meet the new and expanding needs of SWP water users. The bulk of samples collected for this monitoring effort have been analyzed by DWR’s internal laboratory, Bryte Lab. Additional tests outside of Bryte Lab’s capability or capacity have been analyzed at non-DWR affiliated laboratories. This dataset covers all samples collected as part of the SWP’s routine water quality monitoring program. This does not include data collected for special projects, specific permit or regulatory requirements, or short-term studies. The following sections provide more information about specific types and groups of samples and their data analysis and availability. ___Standard Water Quality Analytes:___ This group of data contains the most commonly sampled for analytes and parameters for this program. This includes anions, cations, nutrients, organic carbon, solids, and field measurements such as conductivity, pH, turbidity, and wate…

C2VSimCG Version 2025 - Draft
type: Dataset
description: Draft Coarse Grid California Central Valley Groundwater-Surface Water Simulation Model (released January 1, 2026). C2VSimCG v2025 is a computer program that simulates water movement through the linked land surface, groundwater, and surface water flow systems in California’s Central Valley from October 1973 through September 2015. The C2VSimCG model contains monthly historical stream inflows, surface water diversions, precipitation, land use, and crop acreages. C2VSimCG dynamically calculates crop water demands, allocates contributions from precipitation, soil moisture and surface water diversions, and calculates the groundwater pumping required to meet the remaining demand. It simulates the historical response of the Central Valley’s groundwater and surface water flow system to historical stresses and can also be used to simulate the response to projected future stresses. The C2VSimCG version 2025 model package includes model input files, GIS data, model report and a short document describing how to run the model.

i03 Groundwater Sustainability Agencies
type: Dataset
description: The passage of the Sustainable Groundwater Management Act (SGMA) in 2014 set forth a statewide framework to help protect groundwater resources over the long-term. SGMA requires local agencies to form groundwater sustainability agencies (GSAs) for the high- and medium-priority basins. GSAs develop and implement groundwater sustainability plans (GSPs) to avoid undesirable results and mitigate overdraft within 20 years. GSA boundaries are managed through the SGMA Portal. This dataset represents the current GSA boundaries and includes attributes such as GSA contacts and GSA boundary status. The GSA formation process is completed via the SGMA Portal and includes three primary steps, which are discussed in greater detail in Water Code § 10723.8. These steps include: 1) a local agency or group of local agencies submits a GSA formation notice to the SGMA Portal; 2) the Department of Water Resources (DWR) posts complete notices to the SGMA Portal to begin the 90-day GSA formation period; and 3) after 90-days the local agency(s) become an exclusive GSA. Prior to posting a submitted GSA formation notice, DWR staff must verify whether the submitted notice is complete and includes all required information outlined in Water Code § 10723.8. Lastly, only GSA formation notices which are not in overlap with another notice may become exclusive. Posted GSA formation notices which are in overlap are labeled “Yes” in the “Overlap” field of this dataset.

DWR Airborne Electromagnetic (AEM) Surveys Data
type: Dataset
description: #Statewide AEM Surveys Project Overview The Department of Water Resources’ (DWR’s) Statewide Airborne Electromagnetic (AEM) Surveys Project is funded through California’s Proposition 68 and the General Fund. The goal of the project is to improve the understanding of groundwater aquifer structure to support the state and local goal of sustainable groundwater management and the implementation of the Sustainable Groundwater Management Act (SGMA). During an AEM survey, a helicopter tows electronic equipment that sends signals into the ground which bounce back. The data collected are used to create continuous images showing the distribution of electrical resistivity values of the subsurface materials that can be interpreted for lithologic properties. The resulting information will provide a standardized, statewide dataset that improves the understanding of large-scale aquifer structures and supports the development or refinement of hydrogeologic conceptual models and can help identify areas for recharging groundwater. DWR collected AEM data in all of California’s high- and medium-priority groundwater basins, where data collection is feasible. Data were collected in a coarsely spaced grid, with a line spacing of approximately 2-miles by 8-miles. AEM data collection started in 2021 and was completed in 2023. Additional information about the project can be found on the [Statewide AEM Survey website](https://water.ca.gov/Programs/SGMA/AEM "Statewide AEM Survey website"). See the publication below for an overview of the project and a preliminary analysis of the AEM data. DWR continues to collect data and has developed tools to utilize the Statewide AEM Survey data under the [Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "Basin Characterization Program").

AEM Data Viewers
type: Distribution
description: #Overview of Tools The CalGW Subsurface Viewer, SGMA Data Viewer, and AEM 3D Viewer are innovative tools that allows GSAs and stakeholders to view AEM datasets online. These GIS-based tools enable datasets to be visualized in a three-dimensional space, allowing users to zoom in, rotate, and explore the data from multiple angles. The tools can be accessed on a computer or mobile device and do not require downloading data or using specialized software ###AEM Electrical Resistivity AEM electrical resistivity data shows the distribution of electrical resistivity values within the aquifer, where electrical resistivity describes a material's ability to resist an electric current. Generally, materials with higher electrical resistivity values correspond to coarse-grain dominated materials, like sands and gravels. Generally, materials with lower electrical resistivity values correspond to fine-grain dominated materials, like silts and clays, or materials saturated with fluids that have a high concentration of total dissolved solids, like brine or seawater. ###AEM Interpretation for Coarse Fraction AEM electrical resistivity data are interpreted for sediment texture, described as coarse fraction. The interpretation is supported by incorporating existing lithology and geophysical logging data into the transform. ##[CalGW Subsurface Viewer](https://subsurfaceviewer.water.ca.gov/#/?locationType=County&expanded=false&view=chart&dataType=resistivity "CalGW Subsurface Viewer) Data can be viewed by groundwater basin or by county. The **2D Tab** enables users to explore data profiles and switch between electrical resistivity and coarse-fraction values. The viewer also provides a map view showing the locations of subsurface data. The **3D Tab** shows AEM electrical-resistivity values as voxels, which can be explored using the navigation widgets. Depth and profile slices can be generated with the slice widget. ##[SGMA Data Viewer](https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer…

Supporting Data - All Survey Areas - Digitized Lithology and Geophysical Logs
type: Distribution
description: Lithology and geophysical logging data have been digitized to support the Statewide AEM Survey Project. Well lithology and geophysical logs located in a study area were compiled with the objective of obtaining two high-quality logs in each of the Public Land Survey System (PLSS) one-mile square sections that the flight lines cross. High-quality lithology logs were defined as having a verified location accuracy of less than 50 meters (164 feet) and having an average lithology description interval of less than 30 meters (98 feet). High-quality well lithology logs were digitized and tabulated by transcribing the original lithology descriptions and categorized into the free-form, the Unified Soils Classification System (USCS), and texture descriptions. High-quality geophysical logs were defined as being less than 40 years old and having an image quality that could be digitized. Digitized geophysical logs are provided as .las files. All digitized lithology logs with Well Completion Report IDs will be imported back into the OSWCR database. ###Revised Statewide AEM Survey Supporting Data (1/14/2026) * [Survey Area 1: 180/400 Foot Aquifer (partial), East Side (partial), Upper Valley, Forebay Aquifer, Paso Robles, Atascadero (limited), Adelaida (limited), Cuyama Valley](https://data.cnra.ca.gov/dataset/aem/resource/1f5509ec-6d57-4da4-8e7a-660d4c94efcd "Survey Area 1: 180/400 Foot Aquifer (partial), East Side (partial), Upper Valley, Forebay Aquifer, Paso Robles, Atascadero (limited), Adelaida (limited), Cuyama Valley") * [Survey Area 2: Scott River Valley, Shasta Valley, Butte Valley, Tulelake, Fall River Valley (limited), Big Valley (Modoc/Lassen County)](https://data.cnra.ca.gov/dataset/aem/resource/1f2275fb-e001-45b9-9749-3d3a216ab7ef "Survey Area 2: Scott River Valley, Shasta Valley, Butte Valley, Tulelake, Fall River Valley (limited), Big Valley (Modoc/Lassen County)") * [Survey Area 3: Big Valley (Lake County), Ukiah Valley, Santa Rosa Plain, Petaluma Valley, Sonoma Va…

Supporting Data Map
type: Distribution
description: #Supporting Data An important part of the AEM data processing, inversion, and interpretation is the integration of existing supporting data. Supporting data utilized in the Statewide AEM Survey Project include well lithology, geophysical (electrical resistivity) logs, water level measurements, and water quality measurements. Data were compiled from groundwater sustainability agencies, counties, the Online System for Well Completion Reports (OSWCR), the California Geologic Energy Management (CalGEM) Well Finder, the Groundwater Ambient Monitoring and Assessment (GAMA), the California Statewide Groundwater Elevation Monitoring (CASGEM), and the United States Geologic Survey. Additional geophysical logs were purchased from a private company. Data compiled were screened to select high quality wells (described in the sections below). High quality wells were digitized and are provided in the Survey Area’s Supporting Data zip file, linked below: Survey Area 1: https://data.cnra.ca.gov/dataset/aem/resource/1f5509ec-6d57-4da4-8e7a-660d4c94efcd Survey Area 2: https://data.cnra.ca.gov/dataset/aem/resource/1f2275fb-e001-45b9-9749-3d3a216ab7ef Survey Area 3: https://data.cnra.ca.gov/dataset/aem/resource/8d405643-cb7f-4c3d-9333-736eeeb6ffd4 Survey Area 4: https://data.cnra.ca.gov/dataset/aem/resource/eb09227e-32c7-4e11-94f5-359c9b202734 Survey Area 5: https://data.cnra.ca.gov/dataset/aem/resource/366d53c0-6387-42d3-a39f-68aed6291853 Survey Area 6: https://data.cnra.ca.gov/dataset/aem/resource/e40fa03b-f62d-443d-a290-672405c0a3a4 Survey Area 7: https://data.cnra.ca.gov/dataset/aem/resource/ac9ed1fe-1487-4d31-a88b-361a8d584706 Survey Area 8: https://data.cnra.ca.gov/dataset/aem/resource/8c59ee43-1ad0-4860-9746-a4815330aed6 Survey Area 9: https://data.cnra.ca.gov/dataset/aem/resource/1e4bd143-63ec-4c5c-80ed-5dcf07ad1234 Survey Area 10: https://data.cnra.ca.gov/dataset/aem/resource/cfd1b037-cc3d-45d3-a519-38f4a5c37a0d Survey Area 11: https://data.cnra.ca.gov/dataset/aem/resource/2620…

Surface Water - Fecal Indicator Bacteria Monitoring Results
type: Dataset
description: This dataset contains fecal indicator bacteria (FIB) monitoring results collected from surface waters across California. It includes results for _Escherichia coli_ (E. coli), enterococci, fecal coliforms, and total coliforms - key indicators used to assess microbial water quality and potential health risks associated with recreational water use. The data has been cleaned and standardized to ensure consistency and usability. For each valid data point, the dataset also includes calculated 6-week and 30-day geometric means, which are commonly used to evaluate long-term water quality trends and compliance with bacteria water quality objectives. Some records are excluded from the final dataset during processing. These typically include duplicate or replicate results, records with missing or invalid result values, or any data that cannot be used to calculate a geometric mean. These records are saved to the "Excluded Records" data resource. This dataset serves as the primary data source for the Water Boards My Water Quality Portal [Safe to Swim Map](https://mywaterquality.ca.gov/safe-to-swim/content/interactive_map/index.html), which provides the public with timely information about potential health risks associated with water contact recreation at monitored sites. Data is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN) database, BeachWatch database, and the Central Valley Water Board [Lower American River Recreational Water Quality Map](https://experience.arcgis.com/experience/47e27f245e044ac2a8e15083307e75f6/?draft=true&org=waterboards). There is some overlap with the [CEDEN Water Chemistry dataset](https://data.ca.gov/dataset/surface-water-chemistry-results). Both portal datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map.

Dry Domestic Well Susceptibility and Reporting Fact Sheet
type: Distribution
description: This resource includes a brief fact sheet describing DWR's [Dry Domestic Well Susceptibility Analysis](https://data.cnra.ca.gov/dataset/calgw-live/resource/e0bf3d2b-ceca-41ca-876f-d3e378503583) and [Dry Well Reporting System](https://mydrywell.water.ca.gov). DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the Dry Domestic Well Susceptibility within Groundwater Basins Dashboard (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation.

Seasonal Groundwater Level Changes 1, 3, 5 and 10-Year (GIS Feature Service)
type: Distribution
description: Seasonal groundwater level reports provide information from selected water level measurements and are intended to portray the change in seasonal groundwater levels over specific time intervals. Each point shows the calculated difference between the measured groundwater levels from the selected time periods. The change in groundwater level is plotted on the map only if a measurement exists in both time periods at a well. These change values are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development in support of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

20-Year Groundwater Level Trends (GIS Feature Service)
type: Distribution
description: Groundwater levels at selected wells were analyzed using the Mann-Kendall non-parametric test to determine whether a statistically significant trend (declining trend, no trend, or increasing trends in groundwater levels) was present during the specified time period. The data used came only from wells that have at least 10 years of data within the last 21 years. If a statistically significant trend was observed, the Theil-Sen method was used to calculate the estimated slope of the trend line to quantify the decline or increase. These trends are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program.

Current Groundwater Level Statistics (GIS Feature Service)
type: Distribution
description: The DWR Groundwater Level Percentile Statistics are based on the USGS Groundwater Watch concept of comparing the most recent groundwater level measurement to historical measurements for the same month. For a well to be ranked, the most recent measurement must have occurred within the last 18 months, and measurements from at least 10 years must exist for that month. These statistics are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data.

Dry Domestic Well Susceptibility (Python Notebook)
type: Distribution
description: DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the [Dry Domestic Well Susceptibility within Groundwater Basins Dashboard](https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-aoS5Sy) (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation. __If you are currently experiencing a dry domestic well, you can report that to DWR’s [Dry Well Reporting System](www.mydrywell.ca.gov) which will connect you with available local assistance.__ The query for domestic wells was based on DWR’s Online System for Well Completion Reports (OSWCR).

Rates of Preventable Hospitalizations (Age<18) for Selected Medical Conditions by County
type: Dataset
description: The dataset currently contains hospitalization counts and rates, statewide and by county, for 4 conditions plus 3 composite measures. Hospitalizations for these conditions are potentially preventable through access to high-quality outpatient care. The conditions include: asthma (age 2-17), diabetes short-term complications (age 6-17), gastroenteritis (age 3 months-17 years), perforated appendix (retired, 2016), urinary tract infections (age 3 months-17 years), and low birth weight (<2500 grams; retired, 2016). The composite measures (age 6-17) include overall, acute conditions, and chronic conditions. The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

description: The dataset currently contains hospitalization counts and rates, statewide and by county, for 4 conditions plus 3 composite measures. Hospitalizations for these conditions are potentially preventable through access to high-quality outpatient care. The conditions include: asthma (age 2-17), diabetes short-term complications (age 6-17), gastroenteritis (age 3 months-17 years), perforated appendix (retired, 2016), urinary tract infections (age 3 months-17 years), and low birth weight (<2500 grams; retired, 2016). The composite measures (age 6-17) include overall, acute conditions, and chronic conditions. The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

The conditions include: asthma (age 2-17), diabetes short-term complications (age 6-17), gastroenteritis (age 3 months-17 years), perforated appendix (retired, 2016), urinary tract infections (age 3 months-17 years), and low birth weight (<2500 grams; retired, 2016). The composite measures (age 6-17) include overall, acute conditions, and chronic conditions. The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

Polycyclic Aromatic Hydrocarbon Samples - 2011-2024 - OSPR [ds714]
type: Dataset
description: Polycyclic aromatic hydrocarbons (PAHs) are a class of organic compounds found in the environment associated with natural and anthropogenic activities such as the refinement and use of petroleum hydrocarbons as fuels and lubricants. When an oil spill occurs in California, an understanding of pre-spill or ambient levels of PAHs is crucial for understanding the existing environmental conditions before a release occurs. Anthropogenic (e.g., vehicle and boat exhaust, wood burning, industrial activities, oil spills) and natural releases (i.e., forest fires, oil seeps) of PAHs are common sources of these compounds in the environment. Ambient or pre-spill data are critical to identify the need for, and scope of, subsequent environmental sampling, and injury assessment. The Office of Spill Prevention and Response (OSPR) in collaboration with industry representatives (Chevron) and other state and federal trustee agencies (Department of Fish and Game, U.S. Fish and Wildlife Service, Bureau of Land Management, National Oceanic and Atmospheric Administration) have collected environmental samples (e.g., water, sediment, and tissue) for polycyclic aromatic hydrocarbon (PAH) chemical analysis from coastal and inland locations. In addition, plans to collect PAH monitoring data in California for the purpose of being prepared for oil spills and assessing natural resource injuries have been developed. Between 2011 and 2022, Chevron and the Trustees collected samples in Eureka/Humboldt Bay, Richmond, El Segundo, and San Diego, CA for PAH analysis to begin assessing ambient conditions. Chevron and the Trustees have the common understanding that the interpretation of statistical comparisons of these data to spill data (in the event one occurs) must take into consideration the sample size and geographic coverage of the available PAH monitoring data. From 2017 to present, CDFW-OSPR has collected samples in the Feather River Canyon, along the Upper Sacramento River, in Elkhorn Slough and Mo…

Prescription Drugs Introduced to Market
type: Dataset
description: This dataset provides data for new prescription drugs introduced to market in California with a Wholesale Acquisition Cost (WAC) that exceeds the Medicare Part D specialty drug cost threshold. Prescription drug manufacturers submit information to HCAI within a specified time period after a drug is introduced to market. Key data elements include the National Drug Code (NDC) administered by the FDA, a narrative description of marketing and pricing plans, and WAC, among other information. Manufacturers may withhold information that is not in the public domain. Note that prescription drug manufacturers are able to submit new drug reports for a prior quarter at any time. Therefore, the data set may include additional new drug report(s) from previous quarter(s). There are two types of New Drug data sets: Monthly and Annual. The Monthly data sets include the data in completed reports submitted by manufacturers for calendar year 2025, as of January 12, 2026. The Annual data sets include data in completed reports submitted by manufacturers for the specified year. The data sets may include reports that do not meet the specified minimum thresholds for reporting. The program regulations are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/CTRx-Regulations-Text.pdf The data format and file specifications are available here: https://hcai.ca.gov/wp-content/uploads/2024/03/Format-and-File-Specifications-version-2.0-ada.pdf DATA NOTES: Due to recent changes in Excel capabilities, it is not recommended that you save these files to .csv format. If you do, when importing back into Excel the leading zeros in the NDC number column will be dropped. If you need to save it into a different format other than .xlsx it must be .txt Submitted reports that are still under review by HCAI are not included in these files. DATA UPDATES: Drug manufacturers may submit New Drug reports to HCAI for prescription drugs which were not initially reported when they were introduced to market. CT…

Power Outage Areas
type: Dataset
description: The power outages in this layer are pulled directly from the utility public power outage maps and is automatically updated every 15 minutes. This dataset represents only the most recent power outages and does not contain any historical data. The following utility companies are included: Pacific Gas and Electric (PG&E) Southern California Edison (SCE) San Diego Gas and Electric (SDG&E) Sacramento Municipal Utility District (SMUD) Layers included in this dataset: Power Outage Incidents - Point layer that shows data from all of the utilities and is best for showing a general location of the outage and driving any numbers in dashboards. Power Outage Areas - Polygon layer that shows rough power outage areas from PG&E only (They are the only company that feeds this out publicly). With in the PG&E territory this layer is useful to show the general area out of power. The accuracy is limited by how the areas are drawn, but is it good for a visual of the impacted area. Power Outages by County - This layer summaries the total impacted customers by county. This layer is good for showing where outages are on a statewide scale. If you have any questions about this dataset please email GIS@caloes.ca.gov

COVID-19 Dashboard
type: Dataset
description: The dashboard is updated each Friday. __Laboratory surveillance data__: California laboratories report SARS-CoV-2 test results to CDPH through electronic laboratory reporting. Los Angeles County SARS-CoV-2 lab data has a 7-day reporting lag. Test positivity is calculated using SARS-CoV-2 lab tests that has a specimen collection date reported during a given week. Specimens for testing are collected from patients in healthcare settings and do not reflect all testing for COVID-19 in California. Test positivity for a given week is calculated by dividing the number of positive COVID-19 results by the total number of specimens tested for that virus. Weekly laboratory surveillance data are defined as Sunday through Saturday. __Hospitalization data__: Data on COVID-19 and influenza hospital admissions are from Centers for Disease Control and Prevention’s (CDC) National Healthcare Safety Network (NHSN) Hospitalization dataset. The requirement to report COVID-19-associated hospitalizations was effective November 1, 2024. CDPH pulls NHSN data from the CDC on the Wednesday prior to the publication of the report. Results may differ depending on which day data are pulled. Admission rates are calculated using population estimates from the P-3: Complete State and County Projections Dataset (https://dof.ca.gov/forecasting/demographics/projections/) provided by the State of California Department of Finance. Reported weekly admission rates for the entire season use the population estimates for the year the season started. For more information on NHSN data including the protocol and data collection information, see the CDC NHSN webpage (https://www.cdc.gov/nhsn/index.html). Weekly hospitalization data are defined as Sunday through Saturday. __Death certificate data__: CDPH receives weekly year-to-date dynamic data on deaths occurring in California from the CDPH Center for Health Statistics and Informatics. These data are limited to deaths occurring among California residents and are an…

Respiratory Virus Dashboard Metrics
type: Dataset
description: __Note__: On April 30, 2024, the Federal mandate for COVID-19 and influenza associated hospitalization data to be reported to CDC’s National Healthcare Safety Network (NHSN) expired. Hospitalization data beyond April 30, 2024, will not be updated on the Open Data Portal. Hospitalization and ICU admission data collected from summer 2020 to May 10, 2023, are sourced from the California Hospital Association (CHA) Survey. Data collected on or after May 11, 2023, are sourced from CDC's National Healthcare Safety Network (NHSN). Data is from the California Department of Public Health (CDPH) Respiratory Virus State Dashboard at https://www.cdph.ca.gov/Programs/CID/DCDC/Pages/Respiratory-Viruses/RespiratoryDashboard.aspx. Data are updated each Friday around 2 pm. For COVID-19 death data: As of January 1, 2023, data was sourced from the California Department of Public Health, California Comprehensive Death File (Dynamic), 2023–Present. Prior to January 1, 2023, death data was sourced from the COVID-19 case registry. The change in data source occurred in July 2023 and was applied retroactively to all 2023 data to provide a consistent source of death data for the year of 2023. Influenza death data was sourced from the California Department of Public Health, California Comprehensive Death File (Dynamic), 2020–Present. COVID-19 testing data represent data received by CDPH through electronic laboratory reporting of test results for COVID-19 among residents of California. Testing date is the date the test was administered, and tests have a 1-day lag (except for the Los Angeles County, which has an additional 7-day lag). Influenza testing data represent data received by CDPH from clinical sentinel laboratories in California. These laboratories report the aggregate number of laboratory-confirmed influenza virus detections and total tests performed on a weekly basis. These data do not represent all influenza testing occurring in California and are available only at the state level.

Respiratory Virus Weekly Report
type: Dataset
description: __Data is from the California Department of Public Health (CDPH) Respiratory Virus Weekly Report.__ The report is updated each Friday. __Laboratory surveillance data__: California laboratories report SARS-CoV-2 test results to CDPH through electronic laboratory reporting. Los Angeles County SARS-CoV-2 lab data has a 7-day reporting lag. Test positivity is calculated using SARS-CoV-2 lab tests that has a specimen collection date reported during a given week. Laboratory surveillance for influenza, respiratory syncytial virus (RSV), and other respiratory viruses (parainfluenza types 1-4, human metapneumovirus, non-SARS-CoV-2 coronaviruses, adenovirus, enterovirus/rhinovirus) involves the use of data from clinical sentinel laboratories (hospital, academic or private) located throughout California. Specimens for testing are collected from patients in healthcare settings and do not reflect all testing for influenza, respiratory syncytial virus, and other respiratory viruses in California. These laboratories report the number of laboratory-confirmed influenza, respiratory syncytial virus, and other respiratory virus detections and isolations, and the total number of specimens tested by virus type on a weekly basis. Test positivity for a given week is calculated by dividing the number of positive COVID-19, influenza, RSV, or other respiratory virus results by the total number of specimens tested for that virus. Weekly laboratory surveillance data are defined as Sunday through Saturday. __Hospitalization data__: Data on COVID-19 and influenza hospital admissions are from Centers for Disease Control and Prevention’s (CDC) National Healthcare Safety Network (NHSN) Hospitalization dataset.

CDPH-Wastewater Surveillance Data, California
type: Dataset
description: The California Department of Public Health (CDPH) is coordinating with wastewater utilities, local health departments, academic researchers, and laboratories in California on wastewater surveillance for infectious disease pathogens of interest to public health (such as SARS-CoV-2, the virus causing COVID-19, influenza, respiratory syncytial virus (RSV), mpox, and norovirus). Data collected from this network of participants, called the California Surveillance of Wastewaters (Cal-SuWers) Network, are submitted to the U.S. Centers for Disease Control and Prevention (CDC) National Wastewater Surveillance System (NWSS). Collecting and analyzing wastewater samples for the presence of, and amount of (concentration), a specified pathogen target can help inform public health about circulation of that infectious disease within a community. Data from wastewater testing do not replace existing public health surveillance systems but complement them. While wastewater surveillance cannot determine the exact number of infected persons in the area being monitored, it can provide overall trends of pathogen concentration within that community. Please note that data included in the Cal-SuWers Network and available here originate from multiple programs and laboratories. Methodologies for producing wastewater data are not currently standardized, and analyses, comparisons, and aggregations should be done with caution. Wastewater is a complex environmental sample and inherent variability in measured concentrations is expected due to environmental variability, day-to-day differences in sewershed and population dynamics, differences in the amount of shedding between people and pathogens, and laboratory and sampling variability. Please see the CDPH Cal-SuWers, CDC NWSS, and CDC Public Health interpretation and Use of Wastewater Surveillance data webpages for more information.

COVID-19 Vaccine Progress Dashboard Data by ZIP Code
type: Dataset
description: __Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 12+ and age 5+ denominators have been uploaded as archived tables. Starting June 30, 2021, the dataset has been reconfigured so that all updates are appended to one dataset to make it easier for API and other interfaces. In addition, historical data has been extended back to January 5, 2021. This dataset shows full, partial, and at least 1 dose coverage rates by zip code tabulation area (ZCTA) for the state of California. Data sources include the California Immunization Registry and the American Community Survey’s 2015-2019 5-Year data. This is the data table for the [LHJ Vaccine Equity Performance dashboard](https://public.tableau.com/profile/ca.open.data#!/vizhome/LHJVaccineEquityPerformance/MapView?publish=yes). However, this data table also includes ZTCAs that do not have a VEM score. This dataset also includes Vaccine Equity Metric score quartiles (when applicable), which combine the Public Health Alliance of Southern California’s Healthy Places Index (HPI) measure with CDPH-derived scores to estimate factors that impact health, like income, education, and access to health care. ZTCAs range from less healthy community conditions in Quartile 1 to more healthy community conditions in Quartile 4. The Vaccine Equity Metric is for weekly vaccination allocation and reporting purposes only. CDPH-d…

Seismic Compliance Data By County for General Acute Care Hospitals
type: Dataset
description: Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a Structural Performance Category (SPC) which measures the probable seismic performance of building structural systems. Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by January 1, 2020, unless an approved extension has been granted, and all SPC 2 buildings to be removed from providing general acute care services by January 1, 2030. A hospital facility meets the January 1, 2030 requirements if all the general acute care buildings on campus are SPC and NPC compliant. 2030 compliant SPC ratings are either SPC 3, 4, 4D, or 5. 2030 compliant NPC ratings is NPC 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

Continuous Groundwater Level Measurements
type: Dataset
description: DWR continuous groundwater level measurements contains continuous time-series data from automated recorders at sites operated by the Department of Water Resources. Readings are taken at 15-minute to one-hour intervals. Some of the readings are relayed to the California Data Exchange Center. However, most of the monitoring sites are visited once every month or two, when readings are off-loaded from data recorders, then finalized and published. Wells monitored for this dataset are located within Butte, Colusa, Glenn, Mendocino, Modoc, Sacramento, San Joaquin, Shasta, Siskiyou, Solano, Sutter, Tehama, Yolo, and Yuba Counties. Water-level measurements are the principal source of information about changes in groundwater storage and movement in a basin, and how these are affected by various forms of recharge (e.g., precipitation, seepage from streams, irrigation return) and discharge (e.g., seepage to streams, groundwater pumping). Water-level monitoring involves "continuous" or periodic measurements. Continuous monitoring makes use of automatic water-level sensing and recording instruments that are programmed to make scheduled measurements in wells. This provides a high-resolution record of water-level fluctuations. Resulting hydrographs can accurately identify the effects of various stresses on the aquifer system and provide measurements of maximum and minimum water levels in aquifers. Continuous monitoring may be the best technique to use for monitoring fluctuations in groundwater levels during droughts and other critical periods when hydraulic stresses may change at relatively rapid rates, or when real-time data are needed for making water management decisions [see usgs reference](https://ca.water.usgs.gov/sustainable-groundwater-management/groundwater-levels-california.html).

[California's Groundwater Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "California's Groundwater Basin Characterization Program") provides the latest data and information about California’s groundwater basins to help local communities better understand their aquifer systems and support local and statewide groundwater management. Under the Basin Characterization Program, new and existing data (AEM, lithology logs, geophysical logs, etc.) are integrated to create continuous maps and three-dimensional models. To support this effort, new data analysis tools have been developed to create texture models, hydrostratigraphic models, and aquifer flow parameters. Data collection efforts have been expanded to include advanced geologic, hydrogeologic, and geophysical data collection and data digitization and quality control efforts will continue. To continue to support data access and data equity, the Basin Characterization Program has developed new online, GIS-based, visualization tools to serve as a central hub for accessing and exploring groundwater related data in California. Additional information can be found on the [Basin Characterization Program webpage](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "Basin Characterization Program webpage"). #DWR's Evaluation of Groundwater Resources ## Maps and Models DWR is undertaking local, regional, and statewide investigations to evaluate California's groundwater resources and develop state-stewarded maps and models.

Madera & North Kings Local Investigation
type: Distribution
description: The Madera & North Kings Local Investigation focuses on providing information to support floodplain habitat rehabilitation, surface water-groundwater interaction, groundwater recharge, and domestic well assistance activities. The Local Investigation is located within the Kings and Madera subbasins and concentrated on the eastern side of the San Joaquin Valley, between the Upper San Joaquin and Fresno Rivers. Maps and models developed as a part of this Local Investigation support state and local agencies in determining locations for deep recharge (to get water into the main producing zone of the aquifer), shallow recharge (to provide water for vulnerable shallow domestic wells), and multi-benefit floodplain rehabilitation. The Madera & North Kings Local Investigation is a collaboration between the Basin Characterization Program, the Madera and North Kings GSAs, DWR’s Flood-MAR Program, and the Ecological Flood Inundation Potential (EcoFIP) team. ## Maps and Models * [Local Investigation: Madera/North Kings - Texture model (Version 2024.3)](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/ddd6d0d5-68e7-45c1-b9b1-d88de3cf1276 "Local Investigation: Madera/North Kings - Texture model (Version 2024.3)") * [Local Investigation: Madera/North Kings - Aquifer Recharge Potential Maps (Version 2024.3)](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/e5c9e782-bb75-495b-bb22-b659976937ae "Local Investigation: Madera/North Kings - Aquifer Recharge Potential Maps (Version 2024.3)") + ARP Maps and Texture Model can be viewed online on the [SGMA Data Viewer](https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer#basincharacter "SGMA Data Viewer") ## Datasets * [Digitized lithology and geophysical logs - Local Investigation: Madera/North Kings](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/1d08d5ff-427d-4d77-9d39-89caca3c34fe "Digitized lithology and geophysical logs - Local Investigation: Madera/North Kings") * [Digitize…

Digitized Lithology and Geophysical Logs
type: Distribution
description: Lithology and geophysical logging data have been digitized to support the Statewide AEM Survey Project and will continue to be digitized to support Basin Characterization efforts. Well lithology and geophysical logs located in a study area were compiled with the objective of obtaining two high-quality logs in each of the Public Land Survey System (PLSS) one-mile square sections that the flight lines cross. High-quality lithology logs were defined as having a verified location accuracy of less than 50 meters (164 feet) and having an average lithology description interval of less than 30 meters (98 feet). High-quality well lithology logs were digitized and tabulated by transcribing the original lithology descriptions and categorized into the free-form, the Unified Soils Classification System (USCS), and texture descriptions. High-quality geophysical logs were defined as being less than 40 years old and having an image quality that could be digitized. Digitized geophysical logs are provided as .las files. All digitized lithology logs with Well Completion Report IDs will be imported back into the OSWCR database. ### Basin Characterization Digitized Lithology and Geophysical Logs * [Local Investigation: Madera and North Kings](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/1d08d5ff-427d-4d77-9d39-89caca3c34fe "Local Investigation: Madera and North Kings") * [Local Investigation: Western San Joaquin Valley](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/8757704f-6f98-484d-bd4c-eb2fa08ac080 "Local Investigation: Western San Joaquin Valley") * [Regional Investigation: Four County Area (Madera, Fresno, Kings and Tulare counties)](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/41ec1f67-cb0c-4d13-9d81-e514cdb1f880 "Regional Investigation: Four County Area (Madera, Fresno, Kings and Tulare counties)") * [Regional Investigation: San Joaquin Valley (Kern County)](https://data.cnra.ca.gov/dataset/dwr-basin-character…

description: As part of the Basin Characterization Program, DWR will develop new tools and process documents to support the integration and analysis of a wide range of datasets to create maps and models that describe the grain size, hydrostratigraphic properties, and hydrogeologic conceptual properties of California’s aquifers. These tools will be capable of integrating geologic information (from lithology logs), geophysical information (from airborne electromagnetic (AEM) surveys, towed-EM surveys, and geophysical logs), and hydrologic information (water levels and water quality). By combining and assessing various datasets, these tools will help create a more complete picture of California's groundwater basins. All tools, along with process documents, will be made publicly available for local groundwater managers to use to support development of maps and models at a local scale.

California Spotted Owl Range - CWHR B270B [ds3268]
type: Dataset
description: CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: https://www.wildlife.…

Hazardous Waste Id Numbers
type: Dataset
description: Hazardous waste identification (ID) numbers are issued by the U.S. Environmental Protection Agency (Federal EPA ID number) or by the Department of Toxic Substances Control (California State ID number). The ID number identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID number enables regulators to track the waste from its origin to final disposal, a process also referred to as “cradle to grave.” With a few exceptions, most hazardous waste generators must have an ID number before a registered hazardous waste transporter will accept their waste for shipment. All hazardous waste transporters and permitted treatment, storage, and disposal facilities (TSDFs) must have a hazardous waste ID number. For more information, please go to https://dtsc.ca.gov/hazardous-waste-id-numbers/.

SWAMP Data Dashboard
type: Dataset
description: This dataset supports the [SWAMP Data Dashboard](https://gispublic.waterboards.ca.gov/swamp-data/), a public-facing tool developed by the [Surface Water Ambient Monitoring Program](https://www.waterboards.ca.gov/water_issues/programs/swamp/) (SWAMP) to provide accessible, user-friendly access to water quality monitoring data across California. The dashboard and its associated datasets are designed to help the public, researchers, and decision-makers explore and download monitoring data collected from California’s surface waters. This dataset includes five distinct resources: * __SWAMP Stations__ – Geospatial and descriptive information about SWAMP monitoring sites. * __Water Quality Results__ – Field and lab analysis results for chemical and physical parameters measured in water samples. * __Toxicity Summary Results__ – Summarized results from aquatic toxicity tests. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water. * __Habitat Results__ – Data on physical habitat conditions typically collected alongside biological monitoring to provide context for interpreting water quality conditions. Includes scores for the California Stream Condition Index (CSCI) and Algal Stream Condition Index (ASCI). * __Tissue Summary Results__ – Annual summary statistics of contaminant concentrations in aquatic organism tissue samples. The data are derived from raw individual and composite tissue sample results. These data are collected by SWAMP and its partners to support water quality assessments, identify trends, and inform water resource management. The SWAMP Data Dashboard provides interactive visualizations and filtering tools to explore this data by region, parameter, and more. The SWAMP dataset is sourced from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN), which serves as the central repository for water quality data collected by various monitoring programs throug…

Surface Water - Toxicity Results
type: Dataset
description: Surface water toxicity data from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN). CEDEN is the California State Water Board's data system for surface water quality in California, and seeks to include all available statewide data (such as that produced by research and volunteer organizations). Data in CEDEN include field, sediment and water column data collected from freshwater, estuarine, and marine environments. Examples of data in CEDEN come from laboratory, physical and biological analyses and include data types associated with chemical, toxicological, field, bio-assessment, invertebrate, fish, and bacteriological assay assessments. The data resource "Surface Water Toxicity" contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Zip files are provided for bulk data downloads (in csv or parquet file format), and developers can use the API associated with the "Surface Water Toxicity" (csv) resource to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering.

Urban Retail Water Supplier - Water Conservation, Supply, and Demand (June 2014 onwards)
type: Dataset
description: Monthly reports of water use and conservation activities by urban retail water suppliers, which are generally defined as agencies serving over 3,000 service connections or deliveries 3,000 acre-feet of water annually for municipal purposes. The most recent reporting period generally lags by about 2 months, due to the reporting deadline and the necessary subsequent dataset preparation. The full dataset that spans June 2014 to the most recent reporting period is the Per-Supplier Water Supply and Demand resource, which is an updated version of the dataset previously released on the Water Board's [Water Conservation Portal](https://www.waterboards.ca.gov/water_issues/programs/conservation_portal/conservation_reporting.html). Other datasets include the per-water-system supply and demand, representing a subset of the SAFER Clearinghouse dataset, and the conservation actions datasets. See the documentation PDF for data dictionaries and an explanation of the data flag methodology.

COVID-19 Vaccine Progress Dashboard Data
type: Dataset
description: __Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. On 6/16/2023 CDPH replaced the booster measures with a new “Up to Date” measure based on CDC’s new recommendations, replacing the primary series, boosted, and bivalent booster metrics The definition of “primary series complete” has not changed and is based on previous recommendations that CDC has since simplified. A person cannot complete their primary series with a single dose of an updated vaccine. Whereas the booster measures were calculated using the eligible population as the denominator, the new up to date measure uses the total estimated population. Please note that the rates for some groups may change since the up to date measure is calculated differently than the previous booster and bivalent measures. This data is from the same source as the Vaccine Progress Dashboard at https://covid19.ca.gov/vaccination-progress-data/ which summarizes vaccination data at the county level by county of residence. Where county of residence was not reported in a vaccination record, the county of provider that vaccinated the resident is included. This applies to less than 1% of vaccination records. The sum of county-level vaccinations does not equal statewide total vaccinations due to out-of-state residents vaccinated in California. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. Totals for the Vaccine Progress Dashboard and this dataset may not match, as the Dashboard totals doses by Report Date and this dataset totals doses by Administration Date. Dose numbers may also change for a particular Administ…

WDL Ground Surface Displacement - Land Subsidence Monitoring
type: Dataset
description: Borehole extensometers are a more site specific method of measuring land subsidence. These instruments consist of a pipe or cable anchored at the bottom of a well casing. Pipe or cable extend from the bottom of the well, through geologic layers susceptible to compaction, to the ground surface. The pipe or cable is connected to a recorder that measures the relative distance between the bottom of the bore hole to the ground surface. These instruments are capable of detecting changes in land surface elevation to 1/100th of a foot. When land subsidence and water depth monitoring activities are paired together, hydraulic and mechanical properties of the aquifer system can be determined. DWR monitors 11 extensometers in the Sacramento Valley. For more information regarding land subsidence monitoring vist: http://www.water.ca.gov/groundwater/landsubsidence/LSmonitoring.cfm

Prescription Drug Wholesale Acquisition Cost (WAC) Increases
type: Dataset
description: This dataset is comprised of data submitted to HCAI by prescription drug manufacturers for wholesale acquisition cost (WAC) increases that exceed the statutorily-mandated WAC increase threshold of an increase of more than 16% above the WAC of the drug product on December 31 of the calendar year three years prior to the current calendar year. This threshold applies to prescription drug products with a WAC greater than $40 for a course of therapy. Required WAC increase reports are to be submitted to HCAI within a month after the end of the quarter in which the WAC increase went into effect. Please see the statute and regulations for additional information regarding reporting thresholds and report due dates. Key data elements in this dataset include the National Drug Code (NDC) maintained by the FDA, narrative descriptions of the reasons for the increase in WAC, and the five-year history of WAC increases for the NDC. A WAC Increase Report consists of 27 data elements that have been divided into two separate Excel data sets: Prescription Drug WAC Increase and Prescription Drug WAC Increase – 5 Year History. The datasets include manufacturer WAC Increase Reports received since January 1, 2019. The Prescription Drugs WAC Increase dataset consists of the information submitted by prescription drug manufacturers that pertains to the current WAC increase of a given report, including the amount of the current increase, the WAC after increase, and the effective date of the increase. The Prescription Drugs WAC Increase – 5 Year History dataset consists of the information submitted by prescription drug manufacturers for the data elements that comprise the 5-year history of WAC increases of a given report, including the amount of each increase and their effective dates. There are two types of WAC Increase datasets below: Monthly and Annual. The Monthly datasets include the data in completed reports submitted by manufacturers for calendar year 2025, as of January 12, 2026. The Annu…

Power Outages by County
type: Dataset
description: The power outages in this layer are pulled directly from the utility public power outage maps and is automatically updated every 15 minutes. This dataset represents only the most recent power outages and does not contain any historical data. The following utility companies are included: Pacific Gas and Electric (PG&E) Southern California Edison (SCE) San Diego Gas and Electric (SDG&E) Sacramento Municipal Utility District (SMUD) Layers included in this dataset: Power Outage Incidents - Point layer that shows data from all of the utilities and is best for showing a general location of the outage and driving any numbers in dashboards. Power Outage Areas - Polygon layer that shows rough power outage areas from PG&E only (They are the only company that feeds this out publicly). With in the PG&E territory this layer is useful to show the general area out of power. The accuracy is limited by how the areas are drawn, but is it good for a visual of the impacted area. Power Outages by County - This layer summaries the total impacted customers by county. This layer is good for showing where outages are on a statewide scale.

Marbled Murrelet Range - CWHR B240 [ds930]
type: Dataset
description: CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: https://www.wildlife.…

Periodic Groundwater Level Measurements
type: Dataset
description: The DWR Periodic Groundwater Levels dataset contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. This resource also included daily measurements from DWR's automated monitoring network of groundwater sites. For DWRs holdings of groundwater level measurements recorded at more frequent intervals (e.g., hourly), please refer to DWR's “Continuous Groundwater Level Measurements” dataset. For additional information regarding DWR groundwater levels data collection please visit DWR's Groundwater Management website (https://www.water.ca.gov/Programs/Groundwater-Management). The source data can also be accessed directly from two websites. The Water Data Library (http://wdl.water.ca.gov) provides anonymous access to this and other data sets. The CASGEM online system (https://www.casgem.water.ca.gov/OSS) provides authenticated access to only the the periodic groundwater measurements. This dataset is maintained primarily in the DWR Enterprise Water Management database and contains information specific to the location of groundwater level monitoring wells and groundwater level measurements collected at these wells. The Stations resource identifies well location coordinates and other supplementary items about the well type. Measurements resources includes information about the time/date a measurement was collected, the entity collecting the measurement, a measurement indicating the depth to groundwater, and quality information about the measurem…

Groundwater Sustainability Plan Annual Report Data
type: Dataset
description: The Groundwater Sustainability Plan (GSP) Annual Report (AR) datasets contain the following data submitted by Groundwater Sustainability Agencies (GSA) and Alternative Agencies as part of their GSP AR or Alternative to GSP AR: groundwater extraction, surface water supply, total water use, and change in storage volumes for a given water year. All data was originally submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s AR Modules (https://sgma.water.ca.gov/portal/gspar/submitted and https://sgma.water.ca.gov/portal/alternative/annualreport/submitted). Data records within each dataset correspond to either an entire basin or one of multiple GSP areas which collectively correspond to an entire basin. The GSP Regulations established the AR data requirements (23 CCR § 356.2) and tasked DWR with developing an online reporting system for GSAs and Alternative Agencies to electronically submit these data (23 CCR § 353.2). The data fields associated with these datasets were created by DWR to ensure GSAs and Alternative Agencies electronically submitted the required AR data to DWR’s online reporting system, the SGMA Portal (https://sgma.water.ca.gov/portal/). For additional information regarding the AR Modules and the AR submittal process, please view the DWR’s AR resources (https://sgma.water.ca.gov/portal/resources).

West Nile Virus Cases, 2006-present
type: Dataset
description: This dataset contains positive cases of West Nile virus found in humans by county of residence, 2006-present. Humans usually become infected with West Nile virus by being bitten by an infected mosquito. Viruses carried in the mosquito’s saliva enter the blood stream and local tissues where they infect immune cells. Most of the people who do become sick during a WNV infection develop what is referred to as “West Nile fever.” A small percentage of people will develop a much more serious illness called West Nile neuroinvasive disease (WNND). Positive cases in this dataset include both West Nile fever and West Nile neuroinvasive disease.

Data Dictionary - West Nile Virus 2006-present
type: Distribution
description: This dataset contains positive cases of West Nile virus found in humans by county of residence, 2006-present. Humans usually become infected with West Nile virus by being bitten by an infected mosquito. Viruses carried in the mosquito’s saliva enter the blood stream and local tissues where they infect immune cells. Most of the people who do become sick during a WNV infection develop what is referred to as “West Nile fever.” A small percentage of people will develop a much more serious illness called West Nile neuroinvasive disease (WNND). Positive cases in this dataset include both West Nile fever and West Nile neuroinvasive disease.

Spatial CIMIS ETo maps — Daily Reference Evapotranspiration for California
type: Dataset
description: 🔔 **Data now available in Cloud-Optimized GeoTIFF format for faster access!** ### Summary This dataset contains daily grass-reference evapotranspiration (ETo) maps for California at 2 km spatial resolution. The ETo values are expressed in millimeters (mm) per day. Spatial data are provided in EPSG:3310 (NAD83 / California Albers) with units in meters. ETo values are calculated statewide using the ASCE-Penman-Monteith equation (ASCE-PM), with required input parameters including solar radiation, air temperature, relative humidity, and wind speed at two meters height. Daily solar radiation is derived from NOAA GOES satellite imagery using the Heliosat-II model, which converts visible-band satellite images into global horizontal irradiation at ground level. Air temperature, relative humidity, and wind speed are interpolated across the 2 km grid from CIMIS weather station measurements using Spline interpolation. This hybrid method allows spatially distributed ETo maps statewide, filling gaps where station coverage is sparse. Refer to https://cimis.water.ca.gov/SpatialData.aspx and the “Daily reference evapotranspiration for California using satellite imagery and weather station measurement interpolation” (Civil Engineering and Environmental Systems, October 2007) for detailed methodology. ###Update (Dec 2025) Dataset name updated to “Spatial CIMIS ETo maps — Daily Reference Evapotranspiration for California. Added Cloud-Optimized GeoTIFF (COG) format for annual datasets (2004–present) to improve accessibility and enable efficient streaming. Original links to ASCII files remain available. ###Formats Available The dataset is provided in two formats to allows users to choose the format best suited for their analysis and workflows. 1. Original ASCII files — organized in a year/month/day folder structure. 2. Cloud-Optimized GeoTIFF (COG) files — one per year, enabling efficient streaming and subset access without downloading entire files. Each COG contains daily ETo values in…

Provider Suspended and Ineligible List (S&I List)
type: Dataset
description: Medi-Cal law, _Welfare and Institutions Code_ (W&I Code), sections 14043.6 and 14123, mandate that the Department of Health Care Services (DHCS) suspend a Medi-Cal provider of health care services (provider) from participation in the Medi-Cal program when the individual or entity has: * Been convicted of a felony; * Been convicted of a misdemeanor involving fraud, abuse of the Medi-Cal program or any patient, or otherwise substantially related to the qualifications, functions, or duties of a provider of service; * Been suspended from the federal Medicare or Medicaid programs for any reason; * Lost or surrendered a license, certificate, or approval to provide health care; or * Breached a contractual agreement with the Department that explicitly specifies inclusion on this list as a consequence of the breach. __Suspension of Entities Submitting Claims for Suspended Providers__ Suspension is automatic when any of the above events occurs, and suspended Medi-Cal providers will not be entitled to a hearing under the _California Administrative Procedures Act_. Services rendered, prescribed or ordered by a suspended Medi-Cal provider shall not be covered by the Medi-Cal program while the suspension is in effect. _California Code of Regulations_, title 22, section 51303, subdivision (k), provides that at least fifteen (15) days written notice be given to all affected providers. This list constitutes such written notice. Although the period of suspension may have expired, reinstatement rights are not automatic. The provider must petition for reinstatement and re-enroll with DHCS before being reimbursed for services rendered. Providers suspended as a result of a Medicare action must appeal through the Medicare office before applying for re-enrollment with Medi-Cal. In accordance with W&I Code, section 14043.61, subdivision (a), a provider of health care services shall be subject to suspension if claims for payment are submitted under any provider number used by the provider to…

Rates of Preventable Hospitalizations for Selected Medical Conditions by County (LGHC Indicator)
type: Dataset
description: The dataset contains hospitalization counts and rates, statewide and by county, for 10 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; community-acquired pneumonia; urinary tract infection; uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall, acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI (formerly OSHPD) only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

description: The dataset contains hospitalization counts and rates, statewide and by county, for 10 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; community-acquired pneumonia; urinary tract infection; uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall, acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI (formerly HCAI) only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

2015-Q1-Q3 (v5.0) Rates of Preventable Hospitalizations for Selected Medical Conditions by County
type: Distribution
description: The dataset contains hospitalization counts and rates, statewide and by county, for 12 ambulatory care sensitive conditions plus 4 composite measures. Hospitalizations due to these medical conditions are potentially preventable through access to high-quality outpatient care. The conditions include: diabetes short-term complications; perforated appendix; diabetes long-term complications; chronic obstructive pulmonary disease (COPD) or asthma in older adults (age 40 and over); hypertension; heart failure; dehydration; bacterial pneumonia; urinary tract infection; angina without procedure (retired, 2016); uncontrolled diabetes; asthma in younger adults (age 18-39); and lower-extremity amputation among patients with diabetes. The composite measures include overall, acute conditions, chronic conditions, and diabetes (new, 2016). The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

Surface Water - Habitat Results
type: Dataset
description: This data provides results from field analyses, from the [California Environmental Data Exchange Network](https://ceden.org/) (CEDEN). The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Users who want to manually download more specific subsets of the data can also use the **[CEDEN Query Tool](https://ceden.org/find_data_page.shtml)**, which provides access to the same data presented here, but allows for interactive data filtering.

DHCS Medi-Cal Aid Category Grouping Schema
type: Distribution
description: This reference table, maintained by DHCS, displays aid code categories by aid code. Aid codes identify the criteria by which each person qualifies for Medi-Cal and the types of services he or she receives, and make clear whether the services are funded by the State or Federal government or both. An aid code is a combination of two numbers or a letter and a number and is attached to a Medi-Cal beneficiary’s identification numbers. Aid code category refers to a unique grouping of distinct aid codes into broad categories such as CHIP, Seniors and Persons with Disabilities, and Long-Term Care. For a description of each aid code, see the [Medi-Cal Aid Code Master Chart](https://files.medi-cal.ca.gov/pubsdoco/publications/masters-mtp/part1/aidcodes.pdf "Medi-Cal Aid Code Master Chart").
