If you travel from Randfontein towards Westonaria (past Donaldson), you will get the big 4-way stop. Turn left towards JHB. About 2 km after the 4-way you will get a board on you left hand that says Cooks Shaft no.3. On the right you will see a board that says "Camping and Fishing". Turn in there and travel about 1 km. The dam has bass, carp and barbel (kurper as well if I am not mistaken). I have not been there myself but I've heard of good catches being made there and the prices to camp and fish is very reasonable. I will be going past there on Friday afternoon if you want me to go and check and get some info for you. Just PM me and I will let you know.
