The controversial Turkwel Dam was built by the Kenyan government from 1986 to 1991 with the help of France. The plan was to harness the waters of the Turkwel. The project was initially supposed to cost 4 billion Kenyan shillings, but ended up costing more than 20 billion. The dam partially filled the Turkwel Gorge and created the Turkwel Gorge Reservoir.
