At the beginning of its operation, the reservoir had a volumetric capacity of 7,388 hm 3 in an area of 100 ha. The aim of this study was to conduct a bathymetric survey for production of a bathymetric chart and calculation of morphometric parameters. The data collected showed that the Itacarambi river reservoir dam had constant irregularities in its bottom, forming submerged sandbanks, which may be a reflection of silting over the years. A volume of 5.75 hm 3 , that is, 20% of its original capacity, was predicted to be lost in the area occupied by the dam (100 ha). The estimated sedimentation rate was 62,347.8 m 3 year-1 and the lifetime of the reservoir was 115 years since the beginning of operation.
