For land around Biggs Junction, the Sherman County land owner map returns who the tax bill goes to. In this Sherman County guide: where to search, what trusts, estates and LLCs mean, and the next step when you need proof.
A Sherman County land owner map: start here
Use the ORMAP statewide tax lot viewer for a Sherman County land owner map; try the address first, then the owner's name.
Opening the official parcel viewer
Property in and around Erskine appear on the ORMAP statewide tax lot viewer, which opens without registering. For acreage around Grass Valley, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Harmony, the parcel card usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Neighbors and nearby parcels
Look at adjoining lots near Moro for context on nearby owners and uses; it helps with access and boundary questions.
Reading the owner field
Closer to Wasco, the owner field shows who the tax bill names, sometimes a trust or LLC. An estate listed as owner near Harmony usually means title hasn't passed yet after a death, so the personal representative is the contact.
The paper trail behind a parcel
Before you sign anything, pull the recorded deed from the County Clerk; the parcel line is a drawing of it, and that holds around Hay Canyon too. Long-held tracts near Harmony may trace back through several deeds, so a title company earns its fee if money is changing hands.
Land on the county line
Sherman County meets Gilliam County, Wasco County, and Klickitat County, WA, and each of those keeps its own parcel map. Acreage along the edge near De Moss Springs can show up in two county records, so look at the adjacent map as well. For a home near Biggs Junction, our state page links every neighboring county map across Oregon.
Before you lean on the lines
The acreage figure is an estimate; just a licensed surveyor sets the real lines on land around Hay Canyon. If you're looking near Wasco, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Places you'll see on the map
Moro is the county seat, where most land records are kept. Smaller places on the map include Grass Valley, Rufus, Wasco, and Biggs Junction, where town lots give way to larger tracts. Around 1,951 people live in Sherman County (Census estimate, 2023) spread over roughly 824 square miles. Sherman County was formed in 1889, which matters when you trace an old farm's title.
Proof of ownership
For a tract near Biggs Junction, the parcel record is not proof of title; deeds filed with the County Clerk are what count.
Sections, lots and bearings
Oregon is laid out under the Public Land Survey System, so deeds around De Moss Springs reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Grass Valley can be irregular. Keep the legal description for land near Erskine when you talk to a surveyor.
Which office to call
For assessment questions about property around Hay Canyon are handled by the County Assessor, which maintains the tax roll. Questions about what you can build around Rufus need the planning or permitting office, depending on whether the land is inside town limits.
Values and taxes
The record for a parcel near Rufus often lists value and tax amounts; questions about value go to the County Assessor.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Wasco, though signal can drop in rural spots. A screenshot of the parcel near Moro with its ID keeps working without signal.
Contacting an owner politely
A polite note sent to the tax-bill address works better than knocking unannounced about a tract near Grass Valley.
