A large state dam with little fringing emergent vegetation; good shorebird habitat in some years, e.g. in summer 1994 large counts of Blacksmith Plover, Curlew Sandpiper, Little Stint and Ruff recorded. Dabchick noted only in winter, in declining numbers; Cattle Egret occur only in summer, in increasing numbers. Cormorants, herons, egrets, ibises and African Spoonbill commoner in summer; flamingos and most waterfowl commoner in winter. High winter counts of Common Sandpiper and Little Stint in 1992. In winter, total number of species has remained fairly constant, and total count and total biomass curves closely follow those for the three commonest large waterfowl species, namely Egyptian Goose, Spurwinged Goose and Redknobbed Coot. Mild threats are posed by pollution, siltation, boating, hunting/poaching and domestic dogs.
