DIGUE DU MOULINET
In 1959, a dike was built on the Crueize, a tributary of the Colagne, to redirect water to the Truyère, via the Triboulin, in order to produce the 1st renewable energy, hydroelectricity. The overflow dam is 5m high and 141m long. The lake supplies the Castelnau-Lassouts and Grandvals hydroelectric power stations, producing 26.5 million kWh. A 1,660m-long gallery

A 1,660m-long gallery joins the Triboulin and Truyère rivers, diverting water underground from the Lot basin to the Truyère basin beneath the Chauchagrun ridge, which determines the division of the waters. The tunnel was blasted in 1958. The majority of workers on site were Italian. Office, canteen and dormitory: they were housed and fed on site, and often met on Sundays at the Café du Buisson.
Today, the Lac du Moulinet is a concentrate of nature where biodiversity thrives. It's a pleasant place for fishing, swimming and leisure activities.
