The Anuak are a Luo people whose villages are scattered along the banks and rivers of the southwestern area of Ethiopia, with others living directly across the border in South Sudan. The name of these people is also spelled Anyuak, Agnwak, and Anywaa. The Anuak of South Sudan lives in a grassy region that is flat and virtually treeless. During the rainy season, this area floods, so that much of it becomes swampland with various channels of deep water running through it.
