Brief_description
Large dam in Soetdoring Nature Reserve. Regularly has 5000+, occasionally up to 20000, waterbirds; species composition changes markedly with water level. Significant numbers of Darter, Cattle Egret (summer 1997), Egyptian Goose, South African Shelduck, and Red- knobbed Coot (winter 1997); all breed. Numbers of cormorants, herons, egrets, storks, ibises, shorebirds, gulls, terns and some waterfowl, peak in summer; other waterfowl peak in winter. Egyptian Goose increasing in winter, Blacksmith Plover in summer. Good numbers of Black- winged Stilt and Whitewinged Tern in summer 1997; of Dabchick in winter 1997. Important threats are pollution and eutrophication; quelea control operations (e.g. poison sprays) have caused much damage. Badly timed water release from the dam may adversely affect some aquatic birds.
