Young Ewe fishermen from Akanyakrom paddle a group of tourists visiting Bui National Park upriver to see the park's resident hippo population. Thick riparian forest lines the banks of the Black Volta River. Akanyakrom and these upstream areas were flooded by Bui Lake as water levels rose behind Bui Dam after 2012. Hippos were driven upstream by flooding and locally made canoes could no longer be used to ferry tourists because of the lake's winds and waves. Upstream of Akanyakrom, 12 June, 2009.
