Thika River
The Thika River flows through central Kenya and is a tributary of Tana River. The Thika River is a significant source of hydroelectric power in Kenya and provides most of the water supply for Nairobi, Kenya's capital and largest city.
Course
The Thika River originates in the orginates in the Aberdare Range. It flows toward the Indian Ocean as a tributary of the Tana River]]. [1]
Ecology
During the early twentieth century colonial big game hunters noted hippopotamus and crocodiles along the deeper sections of the river.
Water source
Eighty percent of the water supply for Nairobi, Kenya's capital city, comes from the Thika River.[2]
Deforestation and overgrazing have caused soil erosion problems.[2] River flow, reservoir size, and water quality have been reduced by sediments.[2]
Hydroelectricity
Hydroelectric power from the Thika River supplies a significant portion of Kenya's electricity. The first proposal for exploiting the Thika River's hydroelectric potential was put forward shortly after World War I by Guglielmo Marconi as a means for supplying power for a planned radio communications station in Nairobi.[3] Marconi's plan was not implemented, but in 1994 the Thika River Dam was constructed with a resulting water reservoir of 70 million cubic meters.[3][2] The Thika River also contributes to the Masinga Reservoir, which serves the Seven Forks Dams.[2] Taken together, three-quarters of Kenya's electrical supply derives from these dams.[2]
