Lubbock County is a county located in the U.S. state of Texas. As of the 2010 census, the population was 278,831. Its county seat is Lubbock. Lubbock is named for Thomas Saltus Lubbock, a Confederate colonel and Texas Ranger (some sources give his first name as Thompson). Lubbock County, along with neighboring Crosby County, form the Lubbock Metropolitan Statistical Area. The county is also part of the Lubbock– Levelland Combined Statistical Area.
Lubbock County is located in Northwest Texas on the Southern High Plains, within the larger Great Plains of the western United States. The center of the county lies at 33°35' north latitude and 101°52' west longitude. Lubbock, its largest city, is 327 miles northwest of Dallas and 122 miles south of Amarillo. The county measures 893 square miles of flat tableland sloping gently from northwest to southeast, with elevations ranging from 2,900 to 3,400 feet. Its soils are mainly brown to reddish- brown loams and sandy loams, with smaller areas of grayish-brown, silty clay loams. These overlie a clay subsoil and, beneath that, at from two to three feet from the surface, a hardpan of caliche made of calcium carbonate. This caliche forms the Caprock, which has generally prevented streams from cutting their way through the area. Beneath the caliche zone lie beds of water-filled sand of varying thickness but averaging about 300 feet; these make up a part of the great Ogallala Aquifer, formed some ten million years ago as great rivers deposited sand from the Rocky Mountains over an area extending several hundred miles east of the mountains, from what is now Canada to the South Plains of Texas. In 1968 there were 922 small, wind-scoured lakes called playas dotting the county and providing refuge for wildfowl. These are formed by runoff from rainwater and range in size from less than an acre to more than fifty acres. Grasses are predominantly buffalo and blue grama, and in summer there is a profusion of wildflowers, including daisies, buttercups, verbena, and Indian paintbrush, together with scattered yucca and catclaw. Before its settlement the county was treeless, except for cottonwoods and hackberries in the canyons. In later times Chinese elms, oaks, pines, cedars, and a few other trees were introduced, along with mesquite in the nineteenth century. The county is classed as semiarid; its average annual rainfall is 18.41 inches, most of which occurs during the growing season of 208 days. The average minimum temperature in January is 25° F, and the maximum in July averages 92°.
