The Bokaa Dam is a dam on the Metsimotlhabe River, a tributary of the Ngotwane River, in Botswana. It provides water to the capital city of Gaborone. It is operated by the Water Utilities Corporation.[2]
The Bokaa Dam was built in 1990/1991 by damming the Metsimotlhabe River, a tributary of the Ngotwane river just south of Bokaa village.[3] The catchment area is about 3,570 square kilometres (1,380 sq mi). The dam is an earthcore fill structure with a crest level height of 14 metres (46 ft). It was opened in 1993. The dam's surface area when full is 6.6 square kilometres (2.5 sq mi).[1] The reservoir is about 6 kilometres (3.7 mi) in length and over 500 metres (1,600 ft) at its widest.[3]
