Want a copy of the Union County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Felsenthal National Wildlife Refuge. What this Union County guide covers: what's in a plat book, where to look for printed copies, and how the county viewer fills the gaps.
Tracking down a Union County plat book
If the land is near Huttig, plat books are commercial atlases, with owner names on each tract, usually township by township.
Getting to the right map
Lots and tracts near El Dorado can be looked up on the Union County ArcGIS parcel map, which opens without registering. If you only know roughly where the land is, follow Interstate 69 on the aerial and click the parcel itself. For a tract near Old Union, the record panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Editions and availability
Editions come and go depending on publishers, so ask at the courthouse, extension office or a local library near El Dorado.
Next door to Union County
Union County borders Ashley County, Bradley County, Calhoun County, Columbia County, and Ouachita County, and each of those keeps its own parcel map. Acreage along the edge near Ouachita River can show up across two assessors' files, so open the neighboring map too. Around Old Union, our state page lists each neighboring county map for Arkansas.

Plat book vs. recorded plat
For land near Smackover, a plat book is not a recorded plat: the recorded plat at the Circuit Clerk is a legal document, and the atlas is just a guide.
Who handles what
Anything recorded against property around Urbana come from the Circuit Clerk, sometimes only in person. Questions about what you can build around Strong need the planning or permitting office, town or county, depending on location.
The paper trail behind a parcel
On ground around Calion, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are filed with the Circuit Clerk. If you're looking near Calion, have ready the document number listed on the parcel record and the lookup takes minutes.
Union County in a few facts
El Dorado holds the county offices, where most land records are kept. Smaller places on the map include Calion, Strong, Huttig, and Junction City. Around 37,397 people live in Union County (Census estimate, 2023) spread over roughly 1,039 square miles. The county was formed in 1829, so old deeds can run back a long way, at least around Urbana. Features like Ouachita River and Felsenthal National Wildlife Refuge are easy to spot when you zoom out.
What the map can't tell you
The acreage figure is an estimate; just a licensed surveyor establishes the real lines on land around Felsenthal National Wildlife Refuge. Records update in batches, so a fresh transfer around Urbana might lag behind.
Common uses
Farmers, hunters and appraisers near Lawson use plat books for a big-picture view of who owns what.
How land is described here
Arkansas uses the Public Land Survey System, so rural legal descriptions near Mount Holly 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 Lawson can be irregular. Copy the legal description from the record for the parcel near El Dorado before you request a deed or survey.

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.
