Looking for a Williams County plat book? These atlases map who owns rural land, page by page, useful for farms near Epping. What this county guide covers: what's in a plat book, where to look for printed copies, and how the county viewer fills the gaps, at least around Blacktail.
Tracking down a Williams County plat book
For acreage around Blacktail, plat books are commercial atlases, with owner names on each tract, page by page across the county.
Opening the official parcel viewer
Parcels around Williston can be looked up on the Williams County ArcGIS parcel map, a viewer that needs no account. When a rural tract has no street number, pan along US Route 85B and select the outline, for land near Appam included. For a home near Tioga, save the parcel ID while you have it open; each records desk in the county uses it to find the file.
Reading the legal description
North Dakota follows the Public Land Survey System, so rural legal descriptions near Springbrook cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Lake Sakakawea can be irregular. Keep the legal description for land near Ray for any title or survey request.
Who handles what
Deeds, mortgages and recorded plats for land near Alamo sit in the index kept by the County Recorder, sometimes only in person. Questions about what you can build around Springbrook go to planning, building or health offices, depending on whether the land is inside town limits.
Neighboring parcel maps
Williams County borders Richland County, MT, Roosevelt County, MT, Sheridan County, MT, Burke County, and Divide County, all with their own assessor records. Acreage along the edge near Tioga may show up across two assessors' files, so check the neighboring map as well. For a parcel near Springbrook, our state page links every neighboring county map across North Dakota.
Places you'll see on the map
Williston holds the county offices, where most land records are kept. You'll also find Alamo, Epping, Grenora, and Ray, where town lots give way to larger tracts. Roughly 39,113 people call Williams County home (Census estimate, 2023) spread over some 2,078 square miles. Williams County was formed in 1891, which matters when you trace an old farm's title. Features like Lake Sakakawea, Missouri River, and Lake Zahl National Wildlife Refuge help you orient on the aerial.
Where to look for one
Editions come and go depending on publishers, so ask at the courthouse, extension office or a local library near Little Muddy Creek.
The free online alternative
For current names, use the Williams County ArcGIS parcel map, across the county.
A word on accuracy
The acreage figure is an assessed number; just a licensed surveyor can set the real boundary for a parcel near Tioga. For acreage around McGregor, records update in batches, so a deed recorded last month can take weeks to appear.
Not the same thing
Near Trenton, a plat book is not a recorded plat: the recorded plat at the County Recorder is a legal document, and the atlas is just a guide.
Common uses
Farmers, hunters and appraisers near Blacktail use plat books to see ownership across many tracts at once.
Printing your own
Print parcel views near Grenora township by township to build your own up-to-date atlas.
Recorded documents worth pulling
Before you sign anything, get the recorded deed from the County Recorder; the parcel line is a drawing of it, which applies near Little Muddy Creek as much as anywhere. Around Springbrook, bring the book and page from the tax record so staff can find the deed fast.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Lake Sakakawea, though signal can drop in rural spots. A screenshot of the parcel near Missouri River with its ID helps when you meet an owner or agent.

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.
