Lauvitel Lake is the biggest (around 25-35 ha) and the deepest (40-65 m) in the Ecrins National Park. A rocky landslide around 4000 years ago, added to an existing glacial moraine to form a natural dam capable of retaining such a volume of water. The waters of the lake are cold and well oxygenated. They suit several species of fish including the Arctic Char or the Brown Trout which were introduced for anglers. Today the Lake Lauvitel is the subject of numerous scientific studies: physical parameters, sediment, phyto et zooplankton are collected and analyzed.
