The Félou Falls (French: Chutes du Félou) are located on the Sénégal River 15 km upstream of Kayes in western Mali. The river tumbles 13 metres down an irregular series of rocky steps. The waterfalls mark the furthest point from the mouth of the river that can be reached by boat. In 2009 work started on the construction of a 62.3 MW run-of-the-river hydroelectric plant at the falls replacing a small 600 kW plant dating from the 1920s.
