| Brief_description |
| A very large, state-owned impoundment on the Orange River, partly within the Rolfontein and Doornkloof Nature Reserves. Shoreline character variable, depending on water level: when level low, muddy substrate in bays is exposed; when dam full, water reaches base of Karoo koppies. No submergent vegetation, hence lack of Redknobbed Coot: only 1 recorded, in summer. Cormorant, Darter, and Goliath Herons breed, as probably do Egyptian Goose and Yellowbilled Duck. Counts in winter 1996 and summer 1997, when water level was high, produced very few shorebirds but small to good numbers of 30 waterfowl species. Cormorant, Darter, heron and egret numbers peaked in summer, when a count of 112 Darter was noteworthy. Egyptian Goose was common in both seasons, but Yellowbilled Duck was commoner in winter; summer also produced small numbers of six shorebird species. A noteworthy feature was the total of eight Fish Eagles on both counts; several pairs breed here. No threats have been identified. The count comprises sections 1, 2 & 3 of the northern area of the dam. It stretches from the wall upstream to just past Hondeblaf River. |
