I pretty much only fish for muskie.
Not the closest to you, but my favorite little gem is Diamond Lake Oneida County.
https://apps.dnr.wi.gov/lakes/lakepages/LakeDetail.aspx?wbic=1537100t It's not highly advertised as a muskie lake, but they're there. There's a small canal connecting to Squirrel Lake and muskies swim through to spawn every spring. Not a monster lake, but awesome action. I've caught 44, 42 hybrid, and many other upper 30's-40. It's a hidden gem because the canal is too small to get a big boat through. Kayak, canoe, maybe a 12-14' aluminum low V/jon boat if water is high enough. The public landing in the North Bay is usually really overgrown and hard to find. I purposely bought a small old 14' jon boat to fish this lake.
Next is Upper Gresham Lake. Medium size gem, much easier to get to and has nice ramp for bigger fishing boats. Noth on 51, half way between Arbor Vitae and Manitowish Waters. Kind a ways from you too, but the muskie action on this lake has been phenomenal for me. No big resorts and minimal boat traffic. Plenty of upper 40's muskies. No body fishes it and and drives right by to other lakes. A guide buddy I know introduced me to this one and it's a lake he takes people to often.
Where you are is a little more south than I usually go. I'd probably be fishing Crescent Lake. That's a good fishery and there's some huge muskie and walleye there. Big lake and can have a lot of fishing pressure and boat activity though. Something quieter and people always overlook is the Wisconsin River north of Tomahawk, and really any spot along the way to Rhinelander. I've caught some big lake muskie, and they can fight, but they got another on river muskies. River muskies and smallies are my favorites to fish. And that river is so beautiful. Everyone that goes up north to fish thinks they need to hit lakes and never think about the Wisconsin River. Amazing fishery. Another awesome river for muskie and smallies is the Flambeau River, just south of the dam on the Flowage. Fish it all the way to Park Falls. Maybe the best smallies action anywhere in the state.
