| Brief_description |
| A sub-regional IBA. A state dam on the Vaal River, partly within two nature reserves. It regularly supports over 5000, sometimes over 10 000, waterbirds. There are globally significant counts of Dabchick, Darter, African Spoonbill, Greater Flamingo and Cape Shoveller, and nationally significant counts of six other species, including Goliath Heron. Good numbers of Blacksmith Plover, Blackwinged Stilt and Greyheaded Gull also occur. Large numbers of herons, egrets and cormorants breed. Numbers of most waterfowl peak in winter; counts of most other waterbirds are higher in summer, except for Dabchick, flamingos, Redknobbed Coot, Avocet and Whiskered Tern. Black Egret and Saddlebilled Stork are recorded. Important threats are pollution and eutrophication; mild threats are posed by fishing and boating. |
