Ed,
I hale from just over the border (Lancashire, can't bring myself to name the other side) from "Last of the Summer Wine country" and I can assure you that stream does hold trout. Getting to fish it though is a different matter. A few miles south of there though is a length you can fish for free. Had a great day on there a few years back catching both brown trout and grayling.
Cheers,
C.
