The Tokwe Mukorsi Dam is a concrete-face rock-fill dam on the Tokwe River, just downstream of its confluence with the Mukorsi River, about 72 km (45 mi) south of Masvingo in Masvingo Province, Zimbabwe.[1] Construction on the dam began in June 1998 but stalled in 2008. Salini Impregilo began to finish the dam in 2011. Heavy flooding in February 2014 caused a partial failure on 4 February, on the downstream face of the dam.[2][3] As of late February the dam has not fully breached but the unplanned rising reservoir behind the dam has caused evacuations upstream.[4] When complete, the dam will be 90.3 m (296 ft) tall and withhold a 1,750,000,000 m3 (1,420,000 acre·ft) reservoir. The associated power station will have a 12 MW installed capacity.[5]
