If your on kayak then your best bet will be to go across from the resort to almost inline with the dam wall, there are littel in and out lets there with reed beds. Try and see if you can get to one of these spots quickely becuase thy are hot spots, if not go left from the lodg to the old quary site next to marulanie there are also a few spots you can try, but i did not get huge results there.
The main thing is to pick a spot and stay there becuese if your moving around alot you are reducing your chanches. Alot of guys move to a spot and 30 minutes later thy move to another spot.
Last weekend I only managed to cathe 3 kurper, but 2 of them was over 2kg and 1 was 2.5kg. some of the other boats moved around and caught only small or nothing at all. Even the winning boat stuck to one spot and managed to get a huge kurper with a bunch of small ones.
So my advice is if the kurper arent byting that dosent meen that thy arent there. Its the biggest kurper that wins not the bag with a bunch of small fish in it.
