I have fished it a few times and it can be patchy but don’t be fooled there are a lot of fish in it. My best is 90lb but realistically I’d be aiming for 40-50lb.
Simple approach seems to be the method to the far bank assuming you are on pegs 1-28ish and then pole at 5m and 13m and margins.
Carp and barbel will win it with average sizes around 3-4lb from memory and skimmers a good back up. Pellet, corn and meat are safe baits but have some maggot, if its hard its a saviour for barbel at times.
There are a few flyers on the sunken islands, have a look on google earth their obvious and on a sunny day they are black with fish!!
Enjoy
