Hi Skaby
Beautiful venue with lots of fish and can get very busy at times.
Had success there with worms (can be bought at the shop where you pay entrance fee). Use rietvlei slide trace and normal vaal dam bomb.
You need to wade in to cast to get good distance as the bigger fish are sitting deeper.
Sweet floaties (caramel, raspberry, pinksweets etc) will also get you bites but from small to average fish ... will keep you busy and on your toes. I have noticed that the bigger fish prefer worms (maybe because they have a better protein content). Fish with a loose drag as the fish are skittish. A tight drag will result in fish dropping the bait at the slightest feel of tension on the line.
Be prepared for screaming drags as the bigger carp there are powerful, and make sure you carry a landing net as the water level is very low and landing the bigger carp is very tricky.
Tight lines and looking forward to the report back.
