GUIERS, LAKE

French Lac De Guiers, lake, northwestern Senegal. It is situated 40 miles (64 km) east of the city of Saint-Louis. Lake Guiers is fed by the Bounoum (Ferlo) tributary from the south and empties into the Sngal River to the north. Its water is fresh, and a dam, built in 1916, prevents salt from entering the lake from the Taou River and the Sngal River delta. There are, nevertheless, salt licks used by the pastoral population of the vicinity. Since 1931, Lake Guiers' water has been used for irrigation.
