Omo River, Lake Turkana at Risk from Dams and Plantations

“Dams and irrigated plantations being built in Ethiopia will bring major changes to the flow of the Lower Omo River, which in turn will harm ecosystem functions and local livelihoods all the way to the river’s terminus at Lake Turkana in Kenya. More dams are planned for the basin that would compound the damages.

Here we outline some of the basic changes that can be expected as a result of these developments, and include resources on where to get more information.

Fast Facts

  • The Gibe III reservoir is expected to start filling at the beginning of the next Kiremt rainy season (approximately May 2014); filling the reservoir will take up to three years. During this time, the river’s yearly flow will drop as much as 70%.
  • The Gibe III will provide stable flows year-round that will enable the growth of large commercial agricultural plantations in the Lower Omo. The Kuraz sugar plantation and additional areas identified for cultivation could eventually take almost half of the Omo River inflow to Lake Turkana.
  • These projects will cause a decrease in river flow and the size, length, and number of floods, which will be disastrous for downstream users. This is the first year in which runoff from the Kiremt season, which is vital for flood-recession agriculture, restoration of grazing areas, and fisheries production, will be almost completely blocked.”
