Tonle Srepok

The Srepok River (Vietnamese: Sông Serepôk) is a major tributary of the Mekong River. It runs from Đắk Lắk Province in the Central Highlands of Vietnam through the Ratanakiri and Stung Treng provinces in Cambodia to join the Mekong near Stung Treng town. Its length varies from 406 km to 450 km in which the last 281 km course is in Cambodian territory. The Srepok River, in turn, has three main tributaries: the Krông Nô, Krông Ana, and Ea H'leo Rivers. Before joining the Mekong, the Srepok also merges with the Sesan River and Kong River in Stung Treng province. In Vietnam, it is also called Dak Krong river.

Forming from two tributaries—Krông Nô and Krông Ana rivers in the western side of the South Annamite Mountain Range in Vietnam's Central Highlands province of Đắk Lắk—the Srepok runs through Krông Ana, Buôn Đôn, and Ea Súp districts to the west. Just entering the territory of Cambodia, the Srepok is joined by the Ea H'leo River. In Cambodia, it runs through the Ratanakiri and Stung Treng provinces. In Stung Treng, before entering the Mekong, it is joined first by the Se San River and then by the Se Kong River.
