Brief_description
A dam on the Olifants River. Numbers of cormorants, herons, egrets and Blacksmith Plover peak in summer, and of waterfowl, Kittlitz's and Threebanded Plovers, in winter. Redknobbed Coot is common, especially in winter, but a large count in summer 1995 contributed to the high total count and biomass figures for that survey, which also produced maximum counts of Whitebreasted Cormorant, Common Sandpiper, Little Stint and Greyheaded Gull. A high count of Whiskered Tern was made in summer 1994 and of Whitewinged Tern in summer 1995. Summer counts of Sacred Ibis and Reed Cormorant are declining; those of Blacksmith Plover are increasing. A serious threat is pollution by industrial waste, sewage and fertilisers; important threats are siltation, landfill, boating, water-skiing and fishing. Recent numbers also indicate a high number of domestic waterbird species.
