I have never fished the UP but maybe I can help. You don't say what books you have. If you don't have "Trout Streams of Michigan" it may be helpful. Here is a web site
that has some good information. They also recommend a couple of books. The link takes you to the page that list some different waters to try.
Good luck with your search. I knew a fellow that use to fish Beaver Ponds in the UP. The Michigan Department of Natural Resources may offer some assistance.
