Deer season: public land and Managed Forest Law
The tax roll marks parcels that are government-owned or enrolled in Wisconsin’s forest tax programs. In Walworth County:
- Federal-owned: 90 acres in 9 parcels
- State-owned: 16,488 acres in 433 parcels
- County-owned: 1,678 acres in 48 parcels
- Managed Forest Law, open to public hunting, fishing, hiking, sightseeing and cross-country skiing: 222 acres in 5 parcels
- Managed Forest Law, closed (no public access without permission): 3,176 acres
In WI 2026, color the map by Auxiliary Class of Property to see these parcels, and tap one for the owner and acreage. The acreages are whole-parcel areas from the tax roll: a parcel that is only partly enrolled counts in full, and the tax roll doesn’t show posted areas or access routes. Before you hunt, check the DNR’s map of private forest land open to the public and the signs on the ground.
