Want a copy of the Ferry County plat book? It's a printed atlas of landownership, usually by township, and it's handy for land around Sanpoil River. Covered here for this county: how the atlas is organized, where to find editions, and the free online map that stays current around Curlew.
Getting started with the Ferry County plat book
For property near Columbia River, a plat book is a privately published atlas, that map ownership across the countryside, page by page across the county.
Pulling up a parcel
Your first stop is the Ferry County ArcGIS parcel map; it includes each assessed parcel around Columbia River and Boyds. When a rural tract has no street number, pan along the nearest road and select the outline, whether the land is near Columbia River or elsewhere in the county. For acreage around Barney's Junction, save the parcel ID from that panel; every office in the county asks for it first.
Editions and availability
Libraries near Curlew sometimes keep past atlases, useful for family or title research.
Before you lean on the lines
For property near Curlew, listed acreage is an assessed number; just a licensed surveyor sets the real lines on the ground. For land near Barstow, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Places you'll see on the map
Republic serves as the county seat, where most land records are kept. Other places on the map include Barney's Junction, Barstow, Boyds, and Curlew. Roughly 7,497 people live in Ferry County (Census estimate, 2023) on roughly 2,203 square miles. The county was organized in 1899, so old deeds can run back a long way around Curlew. Features like Sanpoil River, Columbia River, and Colville National Forest make handy reference points on the map.

Two kinds of plat
Closer to Colville National Forest, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Auditor is a legal document, while the atlas is a reference.
Where the recorded documents are
When the details count, get the recorded deed through the County Auditor; the parcel map near Colville National Forest only summarizes it. Out toward Barstow, bring the document number listed on the parcel record and the lookup takes minutes.
Land on the county line
