[1] Since the lake is fed by surplus water from the Senegal River, during the rainy season it can increase to a maximum length of 34 km and a width of up to 8 km,[2] while the water level can fluctuate by as much as 4.29 m.[1] In the marshland along its fringes, Phragmites and Typha reeds are growing, which are cut for thatching.

Several species of snakes, and small mammals such as otters and mongooses, are present.

[2] The lake has been designated an Important Bird Area (IBA) by BirdLife International because it supports significant populations of non-breeding western swamphens, as well as wintering garganeys and northern pintails.

Although the region has seen several agriculture projects aimed at benefiting farmers both by the Islamic Development Bank and The Food Crisis Prevention Network,[5][6][7] like elsewhere in Mauritania, as of 2017[update] significant portions of the local population continued to suffer from living conditions comparable to modern slavery.
