Site summary
Lake Aleg is located in southwest Mauritania, at the eastern end of the Senegal-Mauritania basin. Thanks to its hydric and floristic richness, the lake is a very attractive area, characterized by a high density of transhumant herders around the lake during the dry season.
The lake is located in a large depression, bounded by dune ridges to the north-west and small plateaux to the east. Its surface area depends essentially on hydrological inputs during the rainy season and on run-off from the small surrounding wadis. It can be up to 20 km long and 5 km wide, with an estimated water volume of 66,440,000 m3.
