Location of the Senqunyane River's mouth

The Senqunyane River is a river of central Lesotho. The name means Little Orange River in Sotho. The river rises in the Maluti Mountains in northwest Lesotho, and flows southwards and then westwards for 120 kilometres before joining the Senqu River (Orange River)[1] in the southwest.[2]

The source of the Senqunyane is the meeting point of three districts: Thaba-Tseka District, Berea District and Leribe District. It forms the border between Thaba-Tseke District and first Berea and then Maseru District for much of its length.

Tributaries include the Bokong River,[3] as well as the Jordane River and Likalaneng River, which join the Senqunyane shortly before the Mohale Dam.[4]:33

The Mohale Dam, opened in 2003, is part of the Lesotho Highlands Water Project, diverting water to the Katse Dam and hence to the Gauteng region in South Africa, including the cities of Johannesburg and Pretoria.

The river is home to the rare Rock-catfish ("Austroglanis sclateri").[5] The Semongkoaneng Waterfall acts as a migration barrier separating distinct fish communities.[5]

The Senqunyane Valley is the site of a number of archaeological and rock art sites.[6] The valley was first inhabited in the Middle Stone Age.[6]

The sandstone gorge with steep cliffs poses a problem to access. A notable bridge build in 2011 crosses the river near its confluence with the Orange River.[7][8]
