Yellows in the Steelpoort/Burgersfort area


Hi guys, I hope someone can help me with a bit of info, I do work every month in steelpoort, I usually stay in Chrome Valley lodge, near the Dwars rivier, or Lapeng (on a horrible section between Steelpoort and Lydenburg) are there any of the small rivers in that area that hold any of the yellowfish species? I tried to get to the river section below the De Hoop dam wall, it seemed blocked off, the Dwars rivier looked very good but the water was a bit muddy, the steelpoort river was extremely dirty so I didnt even try.
