The Bumbuna Dam is a concrete-face rock-fill dam on the Seli River near Bumbuna in Tonkolili District, Sierra Leone,[1] and 350 kilometres (220 mi) from the capital of Freetown, the main consumer.

[1] The site for the dam at Bumbuna Falls was first identified in 1971, and construction was begun in 1975.

[3] Work was halted in May 1997, about 85% completed, due to the Sierra Leone Civil War, and did not restart until 2005.

[3] A 26 January 2005 report noted that 33 villages would be affected by the dam, although only one (of 16 households and 135 people) would require resettlement.

[9] In June 2011, the government announced it had awarded the $750 million Phase II project to Joule Africa, a UK-based company.
