N2 - Damming rivers have an impact on the marine natural resources because it can affect the hydrological and biogeochemical cycles in a watershed. Changes influx of nutrients from upstream to downstream can affect fertility of the waters around the mouth of the river and surrounding areas. This paper discusses the differences and similarities of the spatial pattern of chlorophyll-a (chl-a) concentration in the waters areas around mouth of Cimanuk River before and after the functioning of Jatigede Reservoir in in Sumedang District. Spatial data of chlorophyll-a concentration in the study area were obtained from the processing and analysis of Landsat 8 multi temporal data and validation of data is done through water sampling and laboratory testing. This research area was divided into 3 segments, western Cimanuk Estuary region, the waters between the two estuaries, and eastern Cimanuk Estuary region. The results showed that after the functioning of the Jatigede Dam, the distribution of chl-a with a concentration 0.5 - 1 mg/m3 which tend to decrease. The watershed discharge factor significantly affects the distribution of chl-a concentration in the water nearby to land.
