Havng fished it for many years and watching the site experts like : Rob Wootton,Sean Huggins,Bob Greenbury,Brad Titmus and Stu Dalby,Keith,Wilf,John and Matt Hall,Gaz Sadler, i think this is the best approach:
Small method feeder to the island (every peg has a chuck to the centre island approx 20 metres, some depths are a 1′-2′ deep. Fish pole at 16m with wind allowing you to do so and find the far shelf going up. On calmer days use a small waggler about 2gram.
There are chub upto a 1.5lb in there plus the skimmers are the same size so target them if the weather remains cool but when the water warms then the carp will show well . The margins are always good in the last hour.
Bait : Pellet,corn,paste (when its warmer) and meat, maggots also for the chub and bream.
On the deck at 16m is about 6′, noted pegs are :1 ,9,10,18,19,20,39,40 but it can be won from any peg on its day.
Some matches have seen the guys empty 10 tins of corn when the carp feed.
