| Brief_description |
| A farm dam with open water and muddy shoreline, a little reed cover and some grassy banks. Good numbers of Dabchick, Blacknecked Grebe, Yellowbilled Duck, Egyptian and Spurwinged Geese, and Redknobbed Coot, especially in summer. Globally significant numbers of South African Shelduck recorded in summer, but counts have declined sharply, as have summer counts of Yellowbilled Duck and Redknobbed Coot. Muddy shorelines attract good numbers of shorebirds in summer, especially Blacksmith Plover, Curlew Sandpiper and Little Stint; largest counts of Blackheaded Heron, Egyptian Goose and Whitewinged Tern in summer 1997. Inflow of fertilizer runoff poses a threat. |
