Dallam County

Dallam County is located in the far northwestern corner of the Texas Panhandle; its western border abuts New Mexico, and its northern boundary borders Oklahoma. The county seat, Dalhart, is located on the Dallam-Hartley county line in the south central part of the county. Texline, the county's only other incorporated town, is at the intersection of U.S. Highway 87 and the New Mexico border. The county's center lies at approximately 36°15' north latitude and 102°35' west longitude. Dallam County comprises approximately 1,505 square miles of the rolling grasslands of the Panhandle. The terrain is marked by numerous dry arroyos and by the intermittent Rita Blanca, Carrizo, and Coldwater creeks, all of which drain into the Canadian River. The county's sandy, sandy loam, loam, and salty clay loam soils support a variety of natural grasses and trees, as well as numerous crops, including wheat, corn, milo, sorghum, and other grain products. Ranching, the county's dominant industry, utilizes the abundant grasses to produce large numbers of beef cattle, along with some hogs and horses. The annual rainfall averages 17.38 inches, and the temperatures range from an average low of 19° F in January to an average high of 92° in July. The growing season averages 178 days annually.
