Firstly, the lake isn't deep at all. It averages about 3ft and the deapest part of the lake is supposedly 5ft.
I wouldn't recommend it at all, during the close season last year over 40 Carp died. This doesn't help when it is already under stocked. The baliffs said that they were going to re-stock it this year, but i'm not to sure if they are going to/have. Float fishing can be okay at times but still not worth making the trip for.
If you're looking for a place to catch lots of fish on the float then i would look at joining Long Corpse, Fetcham. It's hard to find on the internet because it's a lake that belongs to Leatherhead and district angling society, not sure how much it costs for adults, but it's £30 for juniors. Last season i went for a day trip and caught over 70 fish averaging 1lb, mainly Carp, some Goldfish(seriously) and Tench. All caught on luncheon meat.
