Lac de Pont, Artificial reservoir in Pont-et-Massène, France

Lac de Pont is an artificial reservoir nestled within forested surroundings where the water reflects the tree-lined banks. The site features multiple areas designed for different water activities and recreation throughout the year.

Lac de Pont was built between 1878 and 1882 on the Armançon to sustain the water level of the Canal de Bourgogne, completed in 1832. The dam was erected in 1882 and the reservoir filled in 1883. In May 2013 floodwater passing the dam reached 90 m3/s, three times the reservoir's volume, and parts of Pont-et-Massène and lower Semur-en-Auxois were evacuated.

The lake and its banks are used for walking, mushroom and snail gathering, mountain biking, horse riding, climbing, fishing, supervised swimming, pedal boats, canoeing, water skiing and rowing, all under rules set by a prefectoral order of 2 August 2006. A 12 km footpath circles the water, and a campsite with a restaurant stands at Pont-et-Massène.

A walking path circles the entire water body, allowing visitors to explore the surroundings on foot. The route is accessible and works well for strolls throughout the year.

Since 1981 a pumping station at Pont-et-Massène has drawn up to 6,000 m³ of drinking water a day from the lake, serving about sixty communes through membrane filtration lines added in 2002 and 2007. The dam, 24 m high, also holds back the Armançon's spring floods.
