Getting started with the Dallam County plat book
Town lots near Conlen rarely get names on the page, which is where the parcel viewer helps.
Pulling up a parcel
Your first stop is the Dallam CAD interactive map; it includes each tax parcel from Kerrick to Conlen. Without an address in hand, follow the nearest road on the aerial and click the parcel itself, whether the land is near Kerrick or elsewhere in the county. For land near Coldwater, copy the parcel ID before closing the panel; every office in the county will want it.
Limits of the parcel data
Around Coldwater, acreage on the record is an estimate; just a licensed surveyor establishes the real boundary on the ground. Closer to Dalhart, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Editions and availability
Not every county has a current edition, check with local offices and farm stores near Rita Blanca National Grassland.
Places you'll see on the map
Dalhart holds the county offices, home to the main records offices. Other places on the map include Texline, Coldwater, Conlen, and Kerrick, where town lots give way to larger tracts. Around 7,237 people call Dallam County home (Census Bureau estimate, 2023) spread over some 1,503 square miles. Dallam County was organized in 1891, which matters when you trace an old farm's title. Features like Rita Blanca National Grassland make handy reference points on the map.
Deeds, plats and who keeps them
Around Coldwater, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are kept by the County Clerk. Long-held tracts near Rita Blanca National Grassland may trace back through many deeds, and a title company is worth hiring on a real sale.
The free online alternative
For current names, use the Dallam CAD interactive map, across the county, which applies near Rita Blanca National Grassland as much as anywhere.
