I'm kinda late but I haven't had a computer in a few days. I went to the Big Lake with my brother last week and caught 1 keeper and 1 throw back walleye and lots of small perch. All the people we talked to said about the same thing...lots of small ones with few keepers.
As far as fishing by Rudyard, there isn't that many lakes over there. Theres a couple trout lakes that are closed now but I don't know of any other ones. Trout Lake isn't too far though.
