This caldera lake is the largest and deepest (up to 450 m) lake in S.E. Asia. The surrounding steep peaks and slopes (up to 2150 m) are presumably of volcanic origin. A large island is situated in the centre of the lake. There is no riverine input; water supply is by rainfall. An outlet river flows north-east to Tanjung Balige. Area is approximately 112,970 hectares according to Giesen (pers comm 1992).
Lake Danau is 174 km south of Medan in central North Sumatra. Main and provincial roadway surrounds the lake, and the island, Pulau Samosir, is accessible by vehicle from the western side of the mainland. Provincial roadway also runs the perimeter of the island.
