Shanty's south of Hwy 64 need to be removed by March 5th, north of Hwy 64 by March 15th.
The season for most fish ends March 4th, unless you're on the Wisconsin River, including impoundments and sloughs then it's open year round except for musky, lake sturgeon, trout, paddlefish and any endangered fish. I fish Lake Wausau, which is part of the Wisconsin River, so I'm lucky.
