Coastal lagoons are brackish, with water that is less saline than the ocean but not entirely fresh. Lake Piso, the largest lake in Liberia, is a lagoon whose size and salinity depends on the season. During the rainy season, Lake Piso has more freshwater, as rivers drain into its basin. During the dry season, the lake is more dependent on the salty tides of the Atlantic Ocean.
