I fished there quite a lot during the period 1995 to 1998.
The fishing was held by a local club and you paid a day ticket on the bank. It's a very pretty water - an old estate lake built by pick and shovel over 200 years ago. Actually there are two lakes, a small one and the big lake which I fished most of the time.
The large lake contains tench, bream a few roach and there are tales of big eels and pike. The tench are not big, I had nothing much above 5lbs and most of the other anglers there fared no better.
The lakes are also full of jacks. I did quite a lot of pike fishing there yet never had anything over about 6lbs.
The lake is famous, first of all because it was fished quite a lot in the 50s by **** Walker and BB (Denys Watkins Pitchford).
Secondly John Sidley spent weeks on this water after the big eels it is supposed to contain.
Hope this helps.
