I live local but have never fished it. The advertisement in "Get Hooked" (www.gethooked.co.uk)says it is open all year, stocked with carp to 26lb, tench and bream to 8lb and pike. Day or night tickets are available- to be purchased at farmhouse. There are two self catering cottages and a small caravan site at the farm. The location is Wick Farm, Lacock, Nr Chippenham. Tel 01249 730244 mobile 07720 509377 Mr & Mrs King.
The lake is 2.5 acre. I have walked round it a couple of times. I have seen carp anglers bivvied up for the night so I guess they must know there is something worth pursuing. I have been told that the lake is not v deep but it has features.
Hope that helps.
