Brief_description
Part of the Blesbokspruit system, with open water, reedbeds and marshy habitat. Supports a wide variety of waterbirds, usually in small to moderate numbers, but the winter 1994 count was relatively high, with maximum counts of Glossy Ibis, Egyptian and Spurwinged Geese, Yellowbilled Duck and Redbilled Teal. Number of species, total count and total biomass all show a decline during the survey period; winter counts of Greyheaded Gull, Purple Gallinule and several waterfowl are declining, while winter Glossy Ibis numbers crashed after 1994. In contrast, winter numbers of Sacred Ibis are increasing. Egrets, Squacco Heron and Black- crowned Night Heron occur predominantly in summer. Blesbokspruit is severely threatened by discharge of mine water which drastically increases total water volume, maintains artificially high water levels in the dry season, and contains many pollutants, including salt. Reed encroachment is a big problem.
