Hi. I know of dams outside east london. The one is in stuterheim. Its called Gubu dam. Excelent dam. Huge with all the diferent areas u can wade with litle creeks and corners and turns. Stunning place. Then in King Wiliams town also outside east london there is a dam called rooikranz. it has two dams, one with bass and the other a smaller beautiful dam called Maiden dam. I used to fly fish up that way when I used to stay in east london. Sory, but that's the nearest dams I know off. Good luck.
