We'll start with the official link, then cover Tensed and the other towns, land types, property lines and records.
The lay of the land in Benewah County
The county seat is St. Maries; Plummer and Tensed are among the other communities you can zoom to. The map also labels unincorporated places, De Smet, Fernwood, and Parkline among them. For scale: roughly 777 square miles of land and an estimated 10,369 residents as of 2023, per the Census Bureau. That is a rural density, so once you leave Plummer expect a patchwork of farm tracts, woodlots and small acreage splits. Public ground such as Heyburn State Park and McCroskey State Park appears as large unbroken blocks, and the private parcels around them draw hunters and recreation buyers.
Opening the Benewah County plat map
Open the Benewah County ArcGIS parcel map (built on an Esri ArcGIS web map); it is the county's own published map. Zoom until the lot lines show up around St. Maries, then click; the pop-up gives the parcel ID, owner and acreage. The same link lives on our Benewah County county page, along with links for the surrounding area.
How accurate are Benewah County, ID property lines?
On rural tracts near Fernwood, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. The section grid shapes many farm tracts around Fernwood; boundaries often follow quarter-section lines you can spot on the map. For a fence, an addition or a dispute in Benewah County, budget for a licensed survey; it's the answer a court or a lender will accept.
Behind the map: land records in Benewah County
Every line on the Benewah County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Names differ across states, so confirm on the official Benewah County site which office records deeds and plats. If the Benewah County parcel record shows an instrument number, that number is the shortcut to the recorded deed.

Private and public hunting ground in Benewah County
Hunters working the country toward the Latah County line can use the parcel map to put a name on every woodlot and field. Around Heyburn State Park and McCroskey State Park, private tracts can press right up against the public boundary, so check the lines before you walk in.

A landowner near Fernwood is more likely to say yes to a hunter who names the exact parcel and offers a phone number.
Work and land use in Benewah County
The Census Bureau's County Business Patterns counted 263 business establishments in Benewah County in 2022, and the largest groups were construction, agriculture support, forestry and fishing, and retail trade. The sectors that stand out against the national mix are forestry and logging, wood product manufacturing, and heavy and civil engineering construction. Around Plummer, a wooded tract on the map may be a working forest; recent aerials and the deed will show whether timber rights were reserved. That context helps when you read the parcel pattern around St. Maries: jobs and land use move together.
A note on timing and acreage
A lot in Tensed that sold last month may still show the previous owner on the map. Treat Benewah County acreage figures as estimates until a survey confirms them.
