One of the factors causing the former mining pits (void) unable to return to the condition of the initial hue before mining activities were carried out because of this stripping ratio large and non-existent backfilling in the mine opening. As a result, this area will eventually be inundated with water and will eventually turn into new waters in the area, which is referred as pit lake. Therefore, an in-depth study of the current topography of void, morphometric conditions, void water quality and mud sedimentation conditions which are increasing at the bottom void. The purpose of this study is to determine changes in morphological of void Gaharu Kapur, morphometry and prediction of the addition of mud sedimentation deposits in void Gaharu Kapur. This study used a bathymetric usv tool as a bathymetric survey tool void. Water volume on void Gaharu Kapur is 18,687,950 m3. Morphometric characteristics void Gaharu Kapur obtained from this study is extensive void reaching 65.68 Ha with a maximum depth of 89 meters. The residence time of water is 2,90 years. Volume development void Gaharu Kapur is 1,04 which means void Gaharu Kapur has a flat water bottom. relative depth calculation of 9.73% which means void Gaharu Kapur has high stirring stability so it is not easy to experience stirring`. Prediction of the addition of mud sedimentation deposits on void Gaharu Kapur is 381.231,2BCM/year.
