Hi Guys,
If you go to Anglers Den in Centurion (I think thats what it's called, but anyway there are only two fishing shops in Centurion and the other is Bass World) - used to be owned by Charles Stewart (he of great fishing fame). Two of the shop assistants are the guys who control this club - or at least they were, but their game is specimen Carp angling in this dam.
Talk to them, thats how I got there.
Last time I was there though I just paid an enterance fee (R40 I think) and could fish for the day, as long as I stayed on the ski resort side of the dam????
