When land near Dufur catches your eye, the The Dalles GIS map lays out lines, owner names and parcel numbers. This The Dalles guide covers: which viewer to open, how to search it, and what to double-check with records.
Opening the The Dalles GIS map: start here
Parcel maps here are usually run by the county, not the town, so for The Dalles the go-to is the ORMAP statewide tax lot viewer.
Opening the official parcel viewer
Begin with the ORMAP statewide tax lot viewer; it includes every tax parcel around Mosier and Shaniko. For a home near Maupin, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Mosier, The parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Printing and saving
Print or screenshot the parcel near Mosier with its ID visible, which helps later when you ask the assessor or a title company.
The Dalles and the county around it
The Dalles lies within Wasco County, Oregon, so its parcels are on the county's map. As the county seat, The Dalles hosts the courthouse, so deeds and plats are filed in town. For a home near Shaniko, The municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits near Maupin usually follows county rules rather than the town's.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a fence near Dufur may sit some distance off the line on screen. Out toward Dufur, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Troubleshooting the viewer
If the viewer stalls on a phone near Maupin, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Maupin are kept by the County Clerk. Long-held tracts near Maupin may sit on several deeds, so a title company can sort it out if money is changing hands.
Getting answers from the right desk
Recorded documents for a parcel near Mosier are with the County Clerk, sometimes only in person. Zoning, permits and septic questions near Dufur need the planning or permitting office, and the answer depends on jurisdiction.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Mosier, but coverage can be spotty out of town. A screenshot of the parcel near Shaniko with its ID keeps working without signal.
Sections, lots and bearings
Oregon uses the Public Land Survey System, which means a tract near Antelope is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Antelope can be irregular. Write down the legal description for the tract near Antelope when you talk to a surveyor.
Three ways to find a parcel
Acreage around Antelope might not have a street number, so zoom in from the nearest road and click the outline. Around Maupin, searching by parcel number never misses, and it's printed on tax bills.
What the layers show
Switch to the aerial basemap over The Dalles shows roofs, driveways and tree lines next to the parcel edges.
Getting your bearings
The town is the county seat, which is where the courthouse records live around Mosier. Smaller places on the map include Dufur, Mosier, Antelope, and Maupin. Roughly 26,333 people live in Wasco County (Census Bureau estimate, 2023) across roughly 2,381 square miles. Wasco County dates to 1854, so old deeds can run back a long way. Landmarks such as Columbia River and Mount Hood National Forest help you orient on the aerial around Shaniko.
Inside the parcel card
If sale dates appear, they help gauge the market around Antelope are a useful starting point; an appraiser is the real authority.

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.
