The Tokwe Mukorsi Dam is an unfinished concrete-face rock-fill dam on the Tokwe River, just downstream of its confluence with the Mukorsi River, about 72 kilometres (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] By late February the dam had not been fully breached but the unplanned rising reservoir behind the dam caused evacuations upstream.[4] Both upstream and downstream, over 20,000 people were evacuated.[5] Construction of the dam was suspended in June 2014 due to a lack of funding.[6][7] The power station was expected to be commissioned by the end of 2015.[8] It is 90.3 metres (296 ft) tall and creates a 1,750,000,000 m3 (1,420,000 acre⋅ft) reservoir, the largest the in country. The associated hydroelectric power station will have a 12 megawatts (16,000 hp) installed capacity.[9]
In May 2016 the government released $35 million to Salini Impregilio to enable the Italian contractor resume construction work that stopped two years ago owing to payment problems. [10]
