If it's anything like the river further upstream (Cheadle), expect it to be tough. Long fishless stretches, cormorants have seen to that. Pockets of reasonable chub, mostly marked up by cormorants, and an occasional better one, even more marked. There are some outstanding trout, I've had them to 5lb, I've seen pictures of bigger than this.
Good luck
p.s. if I was going to fish it at this time of the year I'd use maggots, fish for an hour in one swim, then move on. Find the fish...
