EW,
Depending on the shape of your lake i would select the most promising feature/swim on each bank (up to four). Bait heavily firstly using fast breakdown pellets, sweetcorn and maggots add boilies (lightly skinned)after about four baitings of small food mix, totalling 5 kilos.No rotten bait to worry about. Carry on walking the water and fishing lightly baited spots if carp located while conditions dictate a trip fishing the trap. Won't be uncaught for long.
Good luck with your quest. and KIS. (Keep it secret!!!).
