I live right next and I walk my dog there, the dam usually dryers up in summer,all I saw was very few tiny banded Tilapia (Vlei Kurper) and nothing else, the is a small river flowing next to it called the Keysers River all you find in there is Mosquito fish,Cape Galaxias, and banded tilapia.I catch them in the river with my throw net and use them for livebait for Bass. :blah
