The Turasha River is a major tributary of the Malewa River, which feeds Lake Naivasha in the Great Rift Valley of Kenya.

[1] As of 1994 there was a plan for impounding the river for rural water supply, which could threaten Lake Naivasha.

[2] It is dammed at an elevation of about 3,000 metres (9,800 ft) to supply fresh water to the town of Nakuru.

[1] About 17,500 cubic metres (620,000 cu ft) of water are diverted to Nakuru daily.

[4] Below the dam the river falls more or less rapidly until it joins the Malewa.
