The river Triouzoune has its source on the Plateau de Millevaches and flows over a length of 46 km. As part of the hydroelectric development of the Dordogne gorges, the construction of a dam on its course has created a 410-hectare lake. A 15 km penstock at the dyke brings the water to the Triouzoune power plant, located upstream of the Aigle dam. This lake has allowed the development of leisure activities such as swimming, boating and golf.
