Go high tech. Check out the Michigan inland lakes program from
Lakemaster lake maps to bring up maps on your PC. You can log fish, add your own details, and get truly accurate GPS coordinates along with many other things. You can also get a version that includes Saginaw Bay. Saginaw Bay is the first body of water they've redone in Michigan with 3 foot contour detail. They have list of the 176 inland Michigan lakes in this program so far. They are adding more and so far, the downloads to add new map info has been free.
It's a great program and extremely cheap when you figure out all you get.
Xtreme Bass Tackle is a Lakemaster dealer. I have the above map, the Lake Erie/St. Clair and the Lake Michigan now. I think they are a steal for the price. I haven't even scratched the surface of what the software allows me to do.
