Want a copy of the Millard County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Fishlake National Forest. This Millard County guide covers: what's in a plat book, where to find editions, and how the county viewer fills the gaps.
Tracking down a Millard County plat book
Closer to Sutherland, a plat book is a privately published atlas, showing rural owners and tract lines, often organized by township.
Opening the official parcel viewer
If the land is near Delta, the no-cost parcel map for this area is the Utah State Parcels viewer, and no login is needed to use it. When a rural tract has no street number, pan along the nearest road and click the parcel itself, which applies near Fillmore as much as anywhere. For acreage around Lake Bonneville, save the parcel ID while you have it open; every records desk in the county uses it to find the file.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Deseret, so load it before you lose signal. A saved image of the lot near Sutherland and its lines is a good backup.
A word on accuracy
For a tract near Deseret, acreage on the record is an estimate; only a licensed surveyor can set the real lines on the ground. If the land is near Abraham, records update in batches, so a deed recorded last month may not show yet.
When a parcel crosses a boundary
Millard County touches Lincoln County, NV, White Pine County, NV, Beaver County, Juab County, and Sanpete County, and each of those keeps its own parcel map. A tract near the line by Lake Bonneville may show up across two assessors' files, so open the adjacent map as well. For property near Leamington, our state page lists each bordering county map across Utah.
Editions and availability
Libraries near Holden sometimes keep past atlases, useful for family or title research.

Which office to call
Recorded documents for a parcel near Lynndyl are with the County Recorder, usually searchable by name or document number. Questions about what you can build around Sutherland are for the local planning and health departments, and the answer depends on jurisdiction.
Between editions
For current names, use the Utah State Parcels viewer, across the county, whether the land is near Lake Bonneville or elsewhere in the county.
Recorded documents worth pulling
For anything that matters, pull the recorded deed from the County Recorder; the parcel line is a drawing of it, which applies near Sutherland as much as anywhere. Long-held tracts around Black Rock may sit on several deeds, and a title company can sort it out if money is changing hands.
Millard County in a few facts
Fillmore is the county seat, which is where the courthouse records live. Other places on the map include Delta, Hinckley, Holden, and Kanosh. Roughly 13,437 people live in Millard County (Census estimate, 2023) across about 6,786 square miles. Millard County dates to 1851, so old deeds can run back a long way. Landmarks such as Lake Bonneville, Sevier Lake, and Fishlake National Forest are easy to spot when you zoom out.
Two kinds of plat
Near Deseret, 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.
Legal descriptions in Utah
Utah is laid out under the Public Land Survey System, so deeds around Lynndyl reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Black Rock can be irregular. Write down the legal description for the tract near Sevier Lake for any title or survey request.
