An IBA. Natural pan and excavated vleis; water levels very variable; much emergent sedge plus mud and sand. Also sewage ponds with Phragmites and Typha. Bird numbers high; globally significant numbers of Cape Shoveller (highest 1995-96), Kelp Gull (1994 and 1995 winters) and Hartlaub's Gull; nationally significant numbers of African Spoonbill, Yellowbilled Duck (winter 1995), African Black Oystercatcher, and Avocet (summer 1993). Highest counts of grebes, pelicans, cormorants, Darter, Redknobbed Coot and Kelp Gull in winter; of geese, Hartlaub's Gull and Cape Wagtail in summer, when shorebird counts also high.
