Srepok River

The Srepok River (Vietnamese: Sông Serepôk) is a significant tributary of the Mekong River. It flows from the Central Highlands of Vietnam's Đắk Lắk Province through Cambodia's Ratanakiri and Stung Treng provinces to join the Mekong near Stung Treng town. Its length is about 406 km, with the final 281 km in Cambodian territory. The Srepok River has three major tributaries: the Krông Nô, Krông Ana, and Ea H'leo Rivers. In Stung Treng province, the Srepok joins the Sesan and Kong rivers before joining the Mekong. It is also known as the Dak Krong River in Vietnam.

The Srepok River is formed by two tributaries, the Krông Nô and Krông Ana rivers, on the western side of the South Annamite Mountain Range in Vietnam's Central Highlands province of Đắk Lắk. It runs through the districts of Krông Ana, Buôn Đôn, and Ea Súp to the west. The Srepok River meets the Ea H'leo River as it enters Cambodian territory. It passes through the Cambodian provinces of Ratanakiri and Stung Treng. Before entering the Mekong, it is joined in Stung Treng by the Se San River and then by the Se Kong River.

The river runs approximately 126 kilometers from the confluence of the Krông Nô and Krông Ana rivers to the Vietnam–Cambodia border. The distance from the border to Stung Treng is approximately 281 kilometers.

Length: 406 km (252 mi- shared with Cambodia)
