Brief_description
A dam on the Bronkhorstspruit River, with some fringing reedbeds, and sometimes (e.g. summer 1995) with good foraging substrates for shorebirds. A good variety of bird species recorded. Small numbers of Great Crested Grebe regular all year, and of Caspian Tern in winter; high count of Cape Wagtail in winter 1993. Greater Flamingo occurred only in summer 1995. Numbers of Dabchick, cormorants and most waterfowl peak in winter, when good counts of Redbilled Teal and Southern Pochard are noteworthy. Number of species, and total counts, declined during the survey period, possibly related to dam water levels. Important threats are residential development, boating and water-skiing; pollution is a mild threat.
