Ethiopian dam threatens Lake Turkana

April 2015

Lake Turkana is currently the world’s largest lake found within a desert region and there are fears for its future as a means of sustaining both local economies and ecology.

What and where is the Gilgel Gibe III dam?

The Gilgel Gibe III dam is the third in a series of five cascade hydroelectric power dams that have been proposed to be built along the River Omo. The River runs from the Shewan Highlands in central Ethiopia to Lake Turkana which straddles the Kenyan-Ethiopian border. Over ninety percent of the lake lies within Kenyan territory. Costing US$1.8 billion to build, the dam is due to be completed in mid-2015, with full power generation in place by the following year. Lake Turkana is currently the world’s largest lake found within a desert region and there are fears for its future as a means of sustaining both local economies and ecology.
