Bintan Island in the Riau Islands Province is classified as a small island (±1170 km2) with limited freshwater resources. The availability of raw water on Bintan Island will certainly be determined by the characteristics of hydrobiological aspects of Bintan Island. Fulfillment of freshwater needs is carried out through the creation of raw water shelters in the form of reservoirs, pond, retention basin, dams, or abandoned bauxite mining pits. One of the raw water sources on Bintan Island is Kolong Enamretention basin. This study aims to examine the hydrological aspects of Kolong Enam retention basin in Bintan Island. The main data used in this study is digital elevation model (DEM) to extract hydrobiological aspects on Bintan Island. In our study found that Bintan Island has nine sub-watersheds. Kolong Enam retention basin is located in the catchment area of Gunung Lengkuas, East Bintan District. The catchment area of Kolong Enam retention basin has an area of 1067,31 ha, which consists of 3 river orders. With regard to vegetation coverage from 2000-2018, it is indicated that there has been a decrease in vegetation coverage in the Kolong Enam retention basin water catchment area.
