Brief_description
A large, state-owned storage dam in the Assegaai River catchment, surrounded by agricultural land (beef and maize production). Shoreline gently sloping; either heavily grazed or with rank grass and weeds. A proposed Ramsar site which holds extremely large numbers of at least 52 waterbird species, concentrated in the 17 bays where rivers enter the dam. Small areas which are regularly counted hold up to 45 000 waterbirds; the entire system may hold 100 000. In drought years the dam provides a refuge for birds from surrounding pans, including Lake Chrissie. Nationally significant numbers of Yellowbilled Duck and Cape Shoveller were recorded, plus high counts of Dabchick, cormorants, ducks, geese, and shorebirds (including some Palaearctic species). Eutrophication, resulting from inflow of agricultural fertilisers, is a potential problem. Other problems could be posed by opencast coal mining and afforostation in the catchment areas. This important site should be monitored on a regular basis. Efforts should be made to enhance the conservation status of this site.
