Where Crawford County deeds and plats are kept
Recorded deeds and plats for Crawford County are kept by the Register of Deeds, while the parcel layer is maintained for tax assessment.

For subdivision lots in Ferryville, the plat book and page on the record leads straight to the recorded plat.
What the map covers, from Prairie du Chien to the back roads
Start your bearings with Prairie du Chien, the county seat, then Bell Center, De Soto, Eastman, and Ferryville. The map also labels unincorporated places, Seneca, Barnum, and Boydtown among them. Crawford County covers about 571 square miles of land; its 2023 population estimate from the Census Bureau was 15,944. Zoom out from Lynxville and the lots turn into fields and timber quickly; a few acreage homesites break up the larger tracts. Along the Kickapoo River, expect long, irregular tracts whose lines follow the water rather than a road.
Who's clicking on Crawford County parcels
Different people come to the Crawford County parcel map for different reasons. Homesteaders eyeing the country near Seneca use acreage and frontage on the record to narrow a long list to a few tracts worth visiting. Anyone hunting for a buildable lot near Gays Mills can spot unbuilt parcels on the aerial layer and look up who owns them. For a new build outside Eastman, the parcel record supplies the lot size and legal description a site plan needs.
Acreage and vacant lot search
A vacant-land search near Ferryville, step by step:
- Zoom out over the countryside around Eastman with the aerial layer on, and look for parcels with no structures.
- Check who owns each open tract near De Soto and where the tax bill goes.
- Measure the road frontage on the map; a sliver of frontage on a road outside Ferryville may not be enough for a driveway permit.
- Compare land values on similar Crawford County tracts to see whether an asking price is in the ballpark.
- For a tract near Ferryville, confirm zoning, septic suitability and flood status before you make an offer.

A lot in De Soto that sold last month may still show the previous owner on the map. The acreage on a De Soto record is what the tax roll uses, and a survey can come out different.
