Buying land in Oregon without looking at the parcel map is like buying a car without opening the hood. For property around Boardman, the Morrow County plat map is free and public.
Up next are the viewer link, a short tour from Lexington to the Grant County line, and the record checks that turn a map click into a firm answer.
Finding a parcel in Morrow County
Open the statewide ORMAP statewide tax lot viewer and zoom toward Lexington; Morrow County's parcels are part of that layer. Zoom to Morrow County and click a tax lot to see the map number, then follow up with the county's assessment records. Bookmark the Platbookmapper page for Morrow County too; we update it when the official map moves.
Who needs this map
The same map serves very different jobs around Boardman.
- Bowhunters and waterfowlers around Boardman use the parcel layer to see which owners control a creek bottom, a woodlot or a field edge.
- Small-farm and homestead buyers looking around Clarke compare tract sizes and shapes on the map before calling a listing agent.
- Current owners in Morrow County pull their parcel before a tax appeal, a refinance or a talk with the neighbor about a fence.
- House hunters looking at Ione use the parcel record as a free check on the listing: lot size, legal description and last recorded sale.
What the map covers, from Heppner to the back roads
Start your bearings with Heppner, the county seat, then Boardman, Ione, Irrigon, and Lexington. The map also labels unincorporated places, Cecil, Clarke, and Eightmile among them. For scale: roughly 2,031 square miles of land and an estimated 12,302 residents as of 2023, per the Census Bureau. Between Boardman and Lexington the parcel lines open up into large holdings, some running to hundreds of acres. Waterfront and bottomland parcels near the Columbia River deserve a second look at the flood layer. Public ground such as Umatilla National Forest and Umatilla National Wildlife Refuge appears as large unbroken blocks, and the private parcels around them draw hunters and recreation buyers.
Private and public hunting ground in Morrow County
Hunters working the country toward the Gilliam County line can use the parcel map to put a name on every woodlot and field. If you're hunting public ground like Umatilla National Forest and Umatilla National Wildlife Refuge, use the parcel map to see where the public boundary meets private land. The Oregon Department of Fish and Wildlife handles licenses, seasons and public-land maps for Morrow County. Ask owners near Irrigon early, ask politely, and send a thank-you after the season.
Work and land use in Morrow County
Morrow County had 215 business establishments in 2022 (County Business Patterns), led by retail trade, accommodation and food services, and health care and social assistance. Relative to the U.S. as a whole, Morrow County is heavy on forestry and logging, utilities, and agriculture and forestry support services. That points to working timberland, so check whether a wooded parcel in Morrow County has been cut recently or is enrolled in a forestry program. It's useful background when you're judging whether a tract near Irrigon will hold its value.
Reading property lines on the Morrow County plat map
Parcel boundaries on the Morrow County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Oregon uses the Public Land Survey System, so rural deeds in Morrow County often describe land by section, township and range, and you can match the call to the grid on the map. For a fence, an addition or a dispute in Morrow County, budget for a licensed survey; it's the answer a court or a lender will accept.
Acreage and vacant lot search
A practical way to find vacant parcels near Ione:
- Zoom out over the countryside around Ione with the aerial layer on, and look for parcels with no structures.
- Check who owns each open tract near Irrigon and where the tax bill goes.
- Measure the road frontage on the map; a sliver of frontage on a road outside Heppner may not be enough for a driveway permit.
- Assessed values lag the market, but comparing tracts near Clarke still shows which ones the county rates higher.
- Last, call the Morrow County planning or health office about permits, septic and floodplain before you commit.
For a tract near Heppner with no road frontage, see how to tell if land is landlocked.
Behind the map: land records in Morrow County
Every line on the Morrow 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 Morrow County website names the one that handles deeds. Easements and rights-of-way are usually in recorded documents, not on the parcel map, so read the deed itself for a tract near Clarke.
Nearby parcel maps
A farm that runs from Morrow County into Grant County will have separate parcel records on each side; the other neighbors are Gilliam County, Umatilla County, Wheeler County, and Benton County, WA. The Oregon county list links every neighboring map from Morrow County.

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.
