I looked at this place last year when I was shoppin. I used to fish it years ago as a kid. I understand its now privately owned (maybe walkden anglers). There was a match on and people were catching nice fish. I was told on the bank that it is members only and no day ticket. Was also told that they limit the number of members and was told that i had pretty much no chance of getting a ticket.
Not sure if true or not and it may be worth a call to one of the tackle shops in walkden to ask for info.
