The southern part of the lake and valley are classified as part of a "réserve naturelle intégrale" since 1995.[1] This classification aims to preserve such areas in their natural state as if entirely unaffected by human activity. This restricted area is forbidden to visitors and is instead reserved exclusively for scientific research,[2] having been recognised in 2012 as an essential protected area for its scientific importance according to an assessment by the International Union for Conservation of Nature.

Geography

The surface of the lake is approximately 25 to 35 hectares, reaching 65 m in depth. The natural water-retaining dam appeared approximately 4000 years ago, when a rockslide added material on top of a pre-existing glacial moraine. For most of the year, no surface water escapes from the lake.[3]

In winter, the thickness of the surface ice layer surpasses one meter. During periods of snowmelt, meltwater overflow from the surrounding summits is well over the porous flow capacity of the lake barrier. As a result, the depth of the lake can increase by 20 m compared to its summer level, before overflowing.
