For a more interactive look, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near McQueen or elsewhere in the county. A tract near McQueen without an address can still be found: zoom in from the nearest road and click inside the land.
Pulling up a parcel
Begin with the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer; it covers every tax parcel in the county, Hollis included. If you only know roughly where the land is, follow the nearest road on the aerial until the lines appear, then click inside the one you want, for land near Arnett included. In and around Arnett, copy the parcel ID from that panel; each records desk in the county will want it.
Questions to ask before you buy
Ask the seller whether the home has flooded on the property near Arnett; getting a quote early keeps the budget honest.
Legal descriptions in Oklahoma
Oklahoma uses the Public Land Survey System, which means a tract near McQueen is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Arnett odd-sized. Write down the legal description for the tract near Hollis for any title or survey request.
A word on accuracy
For land near McQueen, the acreage figure is an estimate; only a licensed surveyor sets the real boundary on the ground. If you're looking near McQueen, records update in batches, so a deed recorded last month may not show yet.
Which office to call
If the acreage or value on a parcel near Arnett looks off go to the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Gould are for the local planning and health departments, depending on whether the land is inside town limits.
Harmon County in a few facts
Hollis holds the county offices, which is where the courthouse records live. Other places on the map include Gould, Arnett, McQueen, and Vinson, where town lots give way to larger tracts. About 2,392 people call Harmon County home (Census estimate, 2023) spread over roughly 537 square miles. Harmon County was formed in 1909, so old deeds can run back a long way.
Land on the county line
The county borders Beckham County, Greer County, Jackson County, Childress County, TX, and Collingsworth County, TX, all with their own assessor records, at least around Arnett. A tract near the line by Gould can be split in two county records, so check the neighboring map before you assume the acreage. For land near Gould, our state page lists each neighboring county map across Oklahoma.
Decoding the flood zone labels
An AE label includes a base flood elevation (BFE), and an unnumbered A zone has none; surveyors near Arnett use that number. If you're looking near McQueen, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the OKMaps (Oklahoma Office of Geographic Information) - Statewide Parcels layer too to confirm you have the right parcel near Hollis.
Where the recorded documents are
With a lot near McQueen, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are kept by the County Clerk. If you're looking near Arnett, bring the instrument number shown in the record panel so staff can find the deed fast.
Lenders and permits
For a parcel near Hollis, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Gould in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.
Water near Hollis
Low-lying fields near Hollis aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near McQueen can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Frequently asked
Do I need flood insurance in Harmon County?
For most people, lenders generally require it for buildings near Arnett in a Special Flood Hazard Area when the loan is federally regulated or insured; elsewhere it's optional.
Why did my flood zone near Gould change?
In most cases, a new study can move a zone line near McQueen; your community is notified before changes take effect.
How do I check the flood zone for an address in Harmon County?
FEMA's free map shows the zone for any spot near McQueen; then confirm the parcel on the county viewer.
What is a LOMA near Vinson?
For most people, FEMA's LOMA process is the usual route when a building near Hollis sits above the base flood elevation; it starts with an elevation survey.
Why don't the lines match my fence near Gould?
In and around Vinson, parcel lines are tax drawings, not surveys, so a fence may sit off the line

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.
