Getting into the Lyon County ArcGIS parcel map
The official map is the Lyon County ArcGIS parcel map, which runs on an Esri ArcGIS web map. Search an address in Garvin, or pan out toward Dudley and click a rural tract; either way the record pops up with owner and acreage. If the map ever goes missing, check the Lyon County, Minnesota listing on Platbookmapper for the new address.
Is there a current Lyon County plat book?
A plat book is the paper cousin of the online parcel map: a township-by-township atlas with owner names, handy in a truck near Marshall. Treat a printed edition as a handy field reference near Garvin and the online map as the current record.
Are the Lyon County property lines accurate?
A Lyon County plat book is built for assessment, not construction. In Lyon County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. Rural Lyon County land sits on the federal survey grid: a deed might call out a quarter of a numbered section in a given township and range. A survey is the only document that settles where a Lyon County boundary actually runs.
The lay of the land in Lyon County
Start your bearings with Marshall, the county seat, then Balaton, Cottonwood, Florence, and Garvin. For scale: roughly 714 square miles of land and an estimated 25,427 residents as of 2023, per the Census Bureau. Town lots in Cottonwood give way to farm tracts and woodlots within a mile or two, and the roads toward Garvin are lined with small acreage splits. Along the Yellow Medicine River, Redwood River, and Cottonwood River, expect long, irregular tracts whose lines follow the water rather than a road.
Hunting land and landowner permission in Lyon County
Getting on private ground in Lyon County is about relationships, and those start with the owner name on the parcel record. Licenses and season dates for the Dudley area come from the Minnesota Department of Natural Resources. In the field near Marshall, respect posted signs and painted boundaries even where the map line looks different.
Behind the map: land records in Lyon County
For land near Marshall, the parcel record is the index; the recorded deed is the source. Names differ across states, so confirm on the official Lyon County site which office records deeds and plats. When the chain of title matters for land near Garvin, ask for the full deed history or hire a title company in Minnesota.
Who's clicking on Lyon County parcels
A lot of different people around Garvin rely on this map. People hunting for a few acres outside Cottonwood use the parcel layer to sort tracts by size and spot ones with good road access. Folks shopping for raw land click through empty parcels near Cottonwood, note the owners, and send letters. Contractors quoting work near Dudley check frontage and lot depth on the map before they drive out. A hunter driving the back roads near Dudley can match a promising woodlot to an owner name in seconds.
Data limits to keep in mind
If a tract near Florence changed hands recently, the recorded deed is more current than the map. The acreage on a Florence record is what the tax roll uses, and a survey can come out different.
Acreage and vacant lot search
Five steps for vacant land in Lyon County:
- Zoom out over the countryside around Balaton with the aerial layer on, and look for parcels with no structures.
- Check who owns each open tract near Florence and where the tax bill goes.
- Check that the tract touches a public road; a landlocked lot near Balaton can be hard to finance and build on.
- Compare land values on similar Lyon County tracts to see whether an asking price is in the ballpark.
- Ask the local offices serving Balaton about building permits and septic rules before you buy.

Measured against national shares, agriculture and forestry support services, nursing and residential care, and heavy and civil engineering construction are overrepresented in Lyon County. Timber tracts in Lyon County change hands for wood value as much as for building, so check the parcel record and the aerial photo together.
