The swims from the new ablition block up until the island are popular and usually deliver if you can locate the fish.
Try to locate the end of the watergrass, usually around 160m out. Usually a patrol route for carp. Initially I use mousetrap method until I get consistent action. I then will put out a few kilos of feed each afternoon to keep the swim alive.
If the smaller Carp start to plague your area,increase your hookbait size and place your Rigs on the outskirts of your feed.
Awesome Carp at the Vlei, you just need to work for them.
