And probably for good reason. Mainly if they report good fishing, then the lake gets hit hard from people as far south as Illinois. Your best chance for fishing information is maybe find a bait shop in that area and try calling them.

I'm orginally from Vilas County...spent almost 20 years there...and I can tell you that probably won't work either. A good bait shop, in my opinion up there, will either tell you they don't have any idea or they will flat out lie to you and lead you in the wrong direction. If you want to be put on fish, hire a guide.
