In the Spring during spawn try looking for fallen trees and shoreline brush. Try a jig or live minnow fished under a bobber close to the fallen trees, etc. Often you have to fish as close a possible to the brush or you won't get many bites. In deeper water fish straight down without a bobber using the same type of baits. You may need to change jig colors until you find the one they want that day. If you don't have a fish finder you could do some drifting in likely looking spots. Once you catch one try to mark that spot because there will probably be more in that area. Good luck.
