For any lot around East Troy, the Mukwonago GIS map shows the outline, the owner of record and a parcel ID. This Mukwonago guide covers: which viewer to open, how to search it, and the limits worth knowing.
Getting started with the Mukwonago GIS map
For land near Lyons, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Property in and around Delavan can be looked up on the Walworth County parcel viewer, a viewer that needs no account. For acreage around East Troy, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Delavan, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
City limits and county records
Mukwonago sits in Walworth County, Wisconsin, and the county assessor maps its lots. If the land is near Elkhorn, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the town limits toward Elkhorn often answers to county rules rather than the town's.
Troubleshooting the viewer
If the viewer stalls on a phone near Delavan, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
What the map can't tell you
The acreage figure is an assessed number; just a licensed surveyor can set the real boundary on land around Lyons. For a tract near East Troy, records update in batches, so a deed recorded last month can take weeks to appear.

How land is described here
Wisconsin uses the Public Land Survey System, so rural legal descriptions near Delavan cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Delavan odd-sized. Write down the legal description for the tract near Elkhorn when you talk to a surveyor.
Searching the map
Vacant ground near Burlington may lack an address, so zoom in from Interstate 43 and click the outline. For a parcel near Lake Geneva, searching by parcel number never misses, and it carries over to every office in the county.
Offices that can help
For assessment questions about property around Lake Geneva go to the county real property listing office, which maintains the tax roll. Questions about what you can build around Delavan go to planning, building or health offices, and the answer depends on jurisdiction.

Where the recorded documents are

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
