What the Green Lake County records include
Counties fill in the statewide schema differently. This is how complete Green Lake County’s 2025 records are:
| Field | Filled in |
|---|---|
| Owner name | 100% of parcels |
| Site (street) address | 58.4% of parcels |
| Assessed or estimated value | 92.6% of parcels |
| Assessed or deeded acres | 91% of parcels |
| Net property tax | 92.6% of parcels |
Only 58.4% of parcels have a street address, which is normal for rural land: fields and woods often have no house number. Search by owner name or parcel ID to find those.

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 Green Lake County:
- Federal-owned: 36 acres in 4 parcels
- State-owned: 19,206 acres in 670 parcels
- County-owned: 404 acres in 36 parcels
- No parcels are listed as open Managed Forest Law land.
- Managed Forest Law, closed (no public access without permission): 3,910 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.
