Whether you're eyeing acreage outside Mitchell or settling a question about your own lot in Mount Vernon, the Davison County plat map is the first stop.
This guide walks through the official link, the kinds of land you'll find around Mount Vernon, and what to do when the map and the ground don't agree.
Davison County at a glance: towns and land
Mount Vernon and Ethan fill out the town list, and Mitchell is where the county seat sits. The Census Bureau puts Davison County at about 436 square miles of land and an estimated 19,922 people (2023). You'll see dense subdivision lots around Mitchell and a looser rural pattern in between. The James River is part of the Davison County landscape, and creek or shoreline tracts are common there.
Getting into the District III regional GIS map
Start with the District III regional GIS map. It's built on the District III planning district web GIS and opens in a normal browser. Once parcel lines appear, click any tract near Ethan to see who owns it and how many acres the county records. Our Davison County, SD page keeps the current link if the official address changes.
Reading property lines on the Davison County plat map
A lot line on the Davison County plat map near Mitchell is a drawing based on deeds, not a measurement taken on site. Because South Dakota is a section-township-range state, the legal description of a rural tract in Davison County reads like a grid reference that you can match to the section lines on the map. A survey is the only document that settles where a Davison County boundary actually runs.
Behind the map: land records in Davison County
Every line on the Davison County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Davison County website names the one that handles deeds. If the Davison County parcel record shows an instrument number, that number is the shortcut to the recorded deed.
Who uses the Davison County parcel map
- A buyer who wants ten or twenty acres near Mount Vernon can rule out most of the wrong tracts from a desk before driving out.
- Anyone hunting for a buildable lot near Mitchell can spot unbuilt parcels on the aerial layer and look up who owns them.
- Builders bidding a house on a lot in Mount Vernon start with the parcel ID and legal description, since permit paperwork usually asks for both.
Acreage and vacant lot search
Here's a simple routine for finding open ground in Davison County using the parcel map:
- Start on the outskirts of Mount Vernon, where empty lots are easy to spot between the houses on the aerial layer.
- Open the record for each empty tract near Ethan and note whether the owner's mailing address is outside Davison County.
- Trace the frontage on any tract near Loomis; without it, access depends on a recorded easement.
- Size up price by comparing a few similar tracts around Ethan on the assessment records.
- For a tract near Mitchell, confirm zoning, septic suitability and flood status before you make an offer.

Private and public hunting ground in Davison County
For hunters, the most valuable part of the Davison County map is the owner name on each tract. Private land requires permission, and the parcel layer tells you exactly who to ask. For licenses, seasons and public hunting land, go to the South Dakota Game, Fish and Parks. Landowners in Davison County hear from a lot of hunters; a specific request that names the parcel stands out.
Work and land use in Davison County
Census business counts for 2022 list 704 establishments in Davison County; retail trade tops the list, with health care and social assistance and accommodation and food services close behind. The sectors that stand out against the national mix are transportation equipment manufacturing, accommodation (hotels, motels, RV parks and camps), and utilities. A buyer looking for a cabin lot near Mitchell may find recreation buyers in the mix too. It's useful background when you're judging whether a tract near Mount Vernon will hold its value.
Two things the map won't tell you
If a tract near Mount Vernon changed hands recently, the recorded deed is more current than the map. The acreage on a Mount Vernon record is what the tax roll uses, and a survey can come out different.

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.
