Lac du Barrage de Sarrans, Reservoir in Cantoin, France.
The reservoir covers approximately 247 acres (100 hectares) and extends 21.7 miles (35 kilometers) along the Truyère River, holding around 79 billion gallons (300 million cubic meters) of water behind a gravity dam that rises 344 feet (105 meters) high.
Construction of the Sarrans Dam began in 1929 and was completed in 1934, employing thousands of workers from across Europe and the Maghreb, with several losing their lives during the dangerous construction process.
The dam once supplied approximately 15 percent of France's electricity needs and remains a symbol of early 20th-century hydroelectric engineering achievements in the region.
The site offers recreational activities including supervised swimming, fishing, boating, cycling routes, and zip lining, with picnic areas and a belvedere providing panoramic views of the dam and surrounding landscape.
A major reservoir emptying in 2014 revealed remnants of the submerged medieval village of Tréboul, including old farmhouses, dry stone walls, and a historic bridge dating back centuries.

Occitanie hosts a wide variety of lakes spread between the Pyrenees and the Massif Central. Natural lakes mainly occupy high-altitude zones in the Pyrenees, where glacial erosion has carved out cirques and basins now filled with water. Lake Oô, located at 4,950 feet (1,507 meters) altitude, receives water from a 984-foot (300-meter) waterfall descending from Lake Espingo. The Bastan lakes form a series of three linked water bodies between 7,217 and 8,202 feet (2,200 and 2,500 meters) near Barèges, while Lake Bethmale, at 3,498 feet (1,065 meters) in Couserans, is surrounded by beech forests. Artificial lakes in the region serve various functions, including water storage, hydroelectric power, and recreational activities. Lake Salagou, created in 1969 in Herault, stands out for its distinctive geological setting: red rocks rich in iron give the landscape a reddish-brown hue. Lake Pareloup, covering about 3,485 acres (1,410 hectares) in Aveyron, is one of the largest reservoirs in the area. Lake Saint-Ferréol, built in the 17th century at the foot of the Black Mountain, supplies the Canal du Midi and demonstrates historic hydraulic engineering. These lakes offer opportunities for hiking, sailing, and windsurfing, especially at Lake Ganguise where the wind blows roughly 300 days per year.
