Plan d'eau d'Embrun, Recreational lake in Embrun, France.

Plan d'eau d'Embrun is a 27-hectare reservoir nestled in the French Alps, created by the construction of the Serre-Ponçon dam. The water body features natural beaches and wooded shorelines, surrounded by the mountains of the Hautes-Alpes region in southeastern France.

The lake came into being in 1960 following the construction of the Serre-Ponçon dam, which transformed a section of the Durance River into a water reservoir and recreational zone. This project was part of broader efforts to harness river resources for power generation and tourism development.

The lake hosts the international Embrun Man triathlon, attracting athletes from around the world who come to test themselves in this demanding mountain competition. The event has made this destination known among endurance sports enthusiasts.

The lake provides visitors with access to shaded parking areas, public showers, and restroom facilities available throughout the year. Swimming conditions are most comfortable during July and August, when water temperatures rise and lifeguards are on duty to monitor the beach.

The 2.6 km 'Au Fil de l'Eau' path circles the lake and is used by walkers and runners training for the Embrun Man triathlon, whose run course passes along these banks. Benches and small beaches punctuate the route, and the northern stretch looks toward the Serre-Ponçon dam.
