If your venue has an island to fish to then you should definitely consider picking a peg with one in it!
Islands are fish-holding magnets whatever the time of year, and should be treated as another margin-type of area. You’ll find shallow water tight up against the island, that shelves away into the main body of the lake.
It may take some time for fish to find the feed in this shallow water but with sanctuary from the island itself or the vegetation overhanging it, carp will feel safe here and stay for longer. Ideally, you’re looking for an island within reach of the long pole. Presentation and feeding will be so much more accurate. However, a Method or pellet feeder and even a waggler in ideal conditions will also catch plenty of fish.
Begin by putting some feed out to the island, either with a pole cup or via several quick casts with the feeder (pellets are hard to beat) and then leave this spot for half-an-hour.
This should be ample time for the fish to find the bait and settle on it.
