The Bort-les-Orgues lake is an artificial lake of 10.72 km2 and results from the creation of the Bort-les-Orgues dam on the high course of the Dordogne. It marks the point where the river enters its gorges and is the first upstream hydroelectric development on the Dordogne.The lake is 21 km long and is shared between the departments of Corrèze, Cantal and Puy-de-Dôme. Although there is no walking tour of the lake yet, a nature-sports festival takes place every year around 14 July, the Aquaterra, which includes trail and water sports.
