Just seen this thread,I took over a lease on a 2 1/2 acre carp lake 15 miles west of Shrewsbury around 6 months ago.We have 20 in the syndicate and also allow day tkts but we dont allow anymore than 5 fish per day.
If ur lookin at a lake around 12 acres,believe me it will take many hours of your time just to keep it in trim with lookin after pegs,banks,fish stocks etc.
Also Carp are not cheap,we have ordered 3 around 16lb for delivery in November and they are around £300 each!!
Good Luck
