Lac Vert, lake at Catus in the Lot department, France

Lac Vert is a 7-hectare reservoir near the town of Catus with gently sloping shores that make it easy to access and walk around. The site features trails for walking and cycling, picnic areas, tennis courts, a beach volleyball court, and a playground for children.

Lac Vert is a reservoir formed by a dam across the Vert, a right-bank tributary of the Lot, and is also fed by several springs. It lies at an elevation of 160 m on the D5 road between Saint-Médard and Catus, with a surface area of 0.07 km².

The lake takes its name from the green colour of its water. It lies on the Vert, a right-bank tributary of the Lot, held back by a dam and fed by several springs, and a leisure centre on its shore offers land and water activities.

The site is open year-round with parking, restrooms, and a snack bar serving paninis, pizzas, crepes, and ice cream. The area is accessible to people with limited mobility, featuring a dock and special water access equipment.

The lake is fed not only by the Vert, the right-bank tributary of the Lot dammed to create it, but also by several resurgences, springs that well up into the basin. The single yellow buoy visible out on the water marks one of these upwellings for swimmers and boaters.
