Duriankang Dam is Batam’s main water supply. The dam was built about 20 years ago; it had filled to it present (maximum) water level by the late 90s. The dam waters cover quite a huge area - 60 sq km - much more than most Batam residents realise. See the satellite photo on this page. Duriangkang’s rural foreshores are an excellent place to get away from Batam’s madding crowds to enjoy some natural tranquility.
Duriangkang Water Catchment Reservoir including the estuary resevoir is built by making resevoir at the estuary of Duriangkang River.

One of several problem of Duriangkang eservoir is erosion as a result of land clearing and building of land at Duriangkang Catchment area.
Based on the research, sedimentation rate at Duriangkang Water Catchment Reservoir area system is as the mayor sources that potentially influence the carrying capacity of Duriangkang Reservoir.ln this study, an influence to carrying capacity of Dunangkang Reservoir is conducted toward sedimentation rate at Duriangkang Reservoir by measuring the water column depth of Duriangkang Reservoir.
