The lake reaches a maximum depth of approximately 40 meters.
It is a tectonic lake formed by the subsidence of a limestone basin during the Jura mountain formation.
The lake provides a significant portion of the drinking water for the surrounding Haut-Doubs region.
In exceptionally cold winters, the entire lake surface can freeze, becoming a site for local ice-skating events.
It sits within the Jura Mountains massif, near the border with Switzerland.
The water quality is consistently monitored, maintaining high standards that support local populations of northern pike, perch, and lake trout.
Lac de Saint-Point is one of the largest natural freshwater lakes in France, situated at an altitude of 850 meters in the Doubs department. Spanning approximately 7 kilometers in length and 1 kilometer in width, the lake formed from a glacial trough during the Würm glaciation. It serves as a central hub for regional water sports, including sailing, paddleboarding, and swimming at designated supervised beaches. Surrounding the water, a well-marked 18-kilometer pedestrian trail circles the entire perimeter, offering terrain suitable for hiking and cycling. The lake is fed primarily by the Doubs River, which exits the lake at its northern tip near the village of Saint-Point-Lac. In winter, the lake surface occasionally freezes, though recreational access onto the ice is strictly regulated based on safety thickness levels. The shoreline features a mix of protected wetlands and managed recreational zones, including the notable villages of Malbuisson and Saint-Point-Lac.

Bring polarized sunglasses to reduce water glare when scouting for fish or aquatic plants.
Use the dedicated wooden boardwalks in marshy sections to protect the fragile lakeside ecosystem.
Plan for rapid weather changes, as the altitude often causes temperatures to drop significantly compared to nearby lowlands.
Attempting to swim outside of designated lifeguard-patrolled zones during summer months due to unpredictable underwater currents.
Water sports facilities are generally seasonal, operating from late spring through early autumn.
Respect noise ordinances near residential lakefront properties and strictly adhere to designated swimming zones.
