Whats the fishing like on rochdale c ?

i used to fish there about 4 years ago but haven't been for along while because of the poisoning to the water killing all the fish. i was going to go back down there over the weekend but not sure worth me checking out. i fish just higher up than morrison on hollinwood ave. used to be a good fish and caught alot of pike perch roach tench and the odd bream but not sure if theres even any fish in there now.
