It is named for its pink waters caused by Dunaliella salina algae and is known for its high salt content, up to 40% in some areas.

The lake is situated 35 km (22 mi) north-east of Dakar,[1] separated from the Atlantic Ocean only by a narrow corridor of dunes, and is named for its pink waters, which are caused by Dunaliella salina algae.

[4][5][6] Salt is exported across the region by up to 3,000 collectors,[7] men and women from all over western Africa, who work 6–7 hours a day.

This transformation threatens the ecosystem and economy of the area, impacting salt farmers, boatmen, souvenir vendors, and tourism.

The flooding destroyed USD$696,000 worth of salt mounds, submerged businesses, and disrupted the lake's unique microbiome, jeopardizing future harvests and tourist visits.
