Standing on the edge of Bui Lake, northwest of Bongase. The lake waters rose behind Bui Dam after 2012, transforming local fishing practices. For generations local Ewe families used the type of canoe pictured here to fish on the Black Volta River. But these can only be used for near-shore fishing on Bui Lake because the lake' s unpredictable winds and waves make them unsafe. Trees still stand in shallow waters along the lake' s edge.
