Lac de Bret, reservoir
Lac de Bret is a small natural lake in the municipality of Puidoux in canton Vaud, Switzerland, located north of Lake Geneva at about 674 meters elevation. The oval-shaped basin stretches approximately 1.5 kilometers in length and reaches 400 meters at its widest point, with maximum water depth of 13 meters.
The first dam at the lake was constructed in 1875 to supply water for the Lausanne-Ouchy funicular, a cable car system carrying passengers up and down the hillside. The lake later became a drinking water reservoir for the nearby city of Lausanne and remains an important water supply for the region today.
The lake takes its name from its natural setting in the region and serves as a gathering place for locals and visitors seeking time in nature. The surrounding open fields and gentle terrain reflect how the community values this accessible green space for outdoor enjoyment.
The lake is open year-round and ideal for walkers exploring quiet trails around its shores. Visitors should know that swimming and motorized boats are not permitted, which preserves the calm of the location and protects the natural habitat.
The lake was shaped by glaciers thousands of years ago and has naturally developed into a nutrient-rich ecosystem supporting varied plant and animal life. This natural evolution makes it a stable part of the local landscape that remains rarely visited despite its use as drinking water supply.
