Thanks for responding, but I looked up the gizzard shad and that just wasn't the right body shape and the dorsal and anal fins were wrong. However after searching through books and online I did find what I think is a positive ID on the DNR fish info page. I really think the only fish that fits what I saw are Walleyes. I found this surprising since I really didn't expect to see walleyes in the Gunpowder. But this would explain why I couldn't get them interested in any sort of baits or lures since walleyes are primarily night feeders. I just wish I'd had my SLR with me and a good polarizer filter so I could've taken pictures of them. I'll just have to start taking a better camera on my fishing trips.
