They are really just getting into the rivers down here over the past two weeks to ten days. I am in the Kenosha/Racine area. I would start to get ready as it will be happening soon.
Rock said it pretty well. At this time there are a lot of fish to be contacted along the shallow shorelines. We have been running plugs and spoons in 10-25 feet of water. If you have any entry where streams enter the lake or there is a hot water outlet or even the water discharges from the public sanitary works. All of these types of water will be warmer than the lake water and should hold fish.
Mark you said it. Anywhere a stream or water enters the lake ie: power plant discharge can be good. Years ago I lived in a pair of waders and wandered the shoreline catching spring fish. Combinations of spoons and shallow diving cranks always produced.
I got hammered pretty hard, lost a couple of key people and now am going to end up working most every day until I get them replaced. Hopefully it ends up making a good situation only better. My brother is almost finished with the tax season and hope he comes down. Will try to get out and if we do this next Monday, hope to post.
