Brief_description
Dam fed by Lourens River; usually no outlet. Until early 1991, habitat in fairly healthy condition with much submerged vegetation providing food for large numbers (up to 478) of Redknobbed Coot. Subsequent eutrophication resulting from fertilisers in water from river led to death of submergents and departure of coot. Counts show large numbers of Whitebreasted Cormorant, Darter, Egyptian Goose and Blacksmith Plover, especially in summer. Good numbers of Reed Cormorant in summer 1995; very few duck except Yellowbilled. 34 Whitewinged Tern recorded summer 1993; 10 Arctic Tern summer 1996, and 21 Avocet winter 1995. Decline apparent in number of species recorded. Eutrophication a critical threat; recent filling of dam during winter rains, when water's fertiliser content lowest, may, if repeated, help alleviate the problem.
