The Crocodile River in Gauteng offers a unique and challenging urban fishery located remarkably close to Johannesburg. While the upper sections near the city face significant water quality challenges, they still support populations of hardy indigenous fish. The river features fast-flowing rapids and long glides, with areas like the spillway below the Cradle Moon Lakeside Conservancy dam creating powerful, aerated water. Access to some productive fishing is surprisingly convenient from the metropolitan area.
