The Gitaru Dam is a rock and earth-filled embankment dam on the Tana River in Kenya. It straddles the border of Embu and Machakos Counties in Eastern Province. The primary purpose of the dam is hydroelectric power generation and it supports a 225 MW power station. Construction on the dam began in 1975 and it was completed in 1978. The power station was not commissioned until 1999. US$63 million in funding for the project was provided by the World Bank. The power station is operated by Kenya Electricity Generating Company and is part of the Seven Forks Scheme.[1][2]

The 30 m (98 ft) tall dam withholds a 16,000,000 m3 (13,000 acre·ft) reservoir. The relatively small reservoir relies on steady releases from the Masinga and Kamburu Dams upstream. The run-of-the-river power station is located underground near the left abutment. It contains two 72 MW and one 81 MW Francis turbine-generators. Water released from the power station is returned to the Tana at the Kindaruma Reservoir via a 4.7 km (2.9 mi) long tailrace tunnel. The difference in elevation between the reservoir and power station affords a net hydraulic head of 136 m (446 ft).[3]
