History

The dam was built by International Construction Zimbabwe (ICZ), a division of the southern African construction giant Murray and Roberts, and was completed in 1988. The dam is located in the Mwenwezi River Valley in the middle section of the river. The area is flat and dry and semi-arid with countless dome-shaped mountains and kopjes in which troops of baboons roam at will. When it was built, a number of villages where displaced and forced to relocate by the government to distant places like the area between Ngundu and

Uses

Electricity Generation

Zimbabwe Electricity Supply Authority (ZESA) has long had plans to generate electricity from the dam but nothing has come of it due to shortage of funding. Studies show, however, that the water availability should make it possible to drive two 350-kilowatt turbines 6 000 hours per year, so as to generate 4.2 gigawatthours per year.

Irrigation

The Manyuchi dam in Zimbabwe was designed to irrigate an agroindustrial complex (2,000 hectares of sugar cane), 40 km downstream from the dam. The dam is to be used primarily to meet irrigation needs. The local population have tried to start irrigation projects using the water from the dam, but lack of funding has derailed their efforts, especially those in nearby Magomana village. It was built to provide water for irrigation for both the commercial and rural irrigation schemes. To date, only the commercial farmers have benefited. None of the 3,476 hectares which were to have been irrigated for the small farmers has been developed. In 1995, at the height of a severe drought in the district and nationally, the dam was over 80 percent full and benefiting only a few large scale commercial farmers. Lately there has been talk of Lapache Irrigation Scheme, a project funded by both the government, Triangle Sugar Ltd and a consortium of non-governmental organizations. The scheme represents the first major step towards the utilization of water from the dam to benefit local communities.Expansion to cost 500 billio

accessed 19 February 2008) Beneficiaries shall mainly be resettled farmers on the Lapache Farm.

Recreation

Previously tourists would go to the area for fishing and other activities. But these days, it is difficult to get there, the roads have been washed away, and one would need a four-wheel drive vehicle to access it.

In popular culture

The dam features in local folklore.
