Looking for a Coryell County plat book? A plat book shows owners and tract lines on township pages, and it's handy for land around Gatesville. This Coryell County guide covers: how the atlas is organized, where to find editions, and the free online map that stays current.
The Coryell County plat book: start here
If the land is near Oglesby, plat books are commercial atlases, showing rural owners and tract lines, usually township by township.
Where the parcel data lives
Parcels around Oglesby can be looked up on the Coryell County ArcGIS parcel map, free to use and open without a login. Closer to Ames, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a parcel near McGregor, save the parcel ID before closing the panel; every office in the county uses it to find the file.
Legal descriptions in Texas
Tracts outside towns near Arnett commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Town lots near South Mountain refer to a recorded plat, making them easier to find. Keep the legal description for land near Mound when you talk to a surveyor.
The paper trail behind a parcel
Before you sign anything, request the recorded deed through the County Clerk; the parcel line is a drawing of it, which applies near Gatesville as much as anywhere. For a home near Mound, bring the book and page from the tax record and the lookup takes minutes.
Where to look for one
Libraries near Mound sometimes keep past atlases, which helps when tracing a farm's history.
A quick look at the area
Gatesville is the county seat, home to the main records offices. You'll also find Copperas Cove, McGregor, Oglesby, and Evant, where town lots give way to larger tracts. Around 84,878 people live in Coryell County (Census estimate, 2023) on some 1,052 square miles. The county was organized in 1854, and some chains of title near Copperas Cove are long.
Between editions
Between printed editions, the Coryell County ArcGIS parcel map shows current owners, across the county.
Before you lean on the lines
For a home near Ater, acreage on the record is an assessed number; only a licensed surveyor can set the real corners on the ground. For a parcel near Flat, records update in batches, so a deed recorded last month can take weeks to appear.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Ater, though signal can drop in rural spots. A printout of the tract near Mound keeps working without signal.
Atlas or legal document
For property near Flat, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the County Clerk is a legal document, while the atlas is a reference.
Offices that can help
Questions about value or the owner field for land near McGregor are handled by the appraisal district, which maintains the tax roll. Zoning, permits and septic questions near Evant are for the local planning and health departments, town or county, depending on location.
Who uses plat books
Buyers and seed dealers around Mound rely on them to see ownership across many tracts at once.
Land on the county line
The county borders Bell County, Bosque County, Hamilton County, Lampasas County, and McLennan County; every one of them runs a separate parcel map, especially near Ames. A tract near the line by Ater can be split in two county records, so look at the adjacent map before you assume the acreage. If the land is near South Mountain, our state page links every neighboring county map for Texas.
