Dispute about the Grand Ethiopian Renaissance Dam

For several years, the governments of Ethiopia, Sudan and Egypt have been engaged in ongoing negotiations about the building of a massive hydroelectric dam on the Blue Nile in Ethiopia. Egypt, which relies heavily on the Nile as a source of freshwater, fears that the dam could reduce the amount of water flowing downstream. Sudan could benefit from cheap electricity generated by the dam and reduced flooding, but is concerned about the impact on its own dams. Now Ethiopia has started filling the reservoir behind the dam.
