I don't know for sure but i read somewhere, l think it was another forum but I can't for the life me remember were because I read that much on the net I forget were I see stuff.
But I do remember reading that the old pond is a private syndicate of 5 friends of the owner of the house you can see from the road.
The larger lakes on the other side of the road is private no fishing at all.
Many years ago it used to be on the Wigan ticket I do remember that as a kid.
I think I may of seen it on the maggot drowners forum.
Have a look on there mate you might find out more information.
