Gaines County, on the southern High Plains of West Texas, is bordered on the west by New Mexico, on the south by Andrews County, on the east by Dawson County, and on the north by Yoakum and Terry counties. Its center point is at 32°45' north latitude and 102°57' west longitude, about eighty miles southwest of Lubbock. The county was named for James Gaines, a merchant who signed the Texas Declaration of Independence. Gaines County covers 1,489 square miles of rolling land that drains to scattered playas and draws. Sandy loam and sandy soils lie over the county's red-clay subsoil and support a growth of mesquite, shinnery, and catclaw. Cedar Lake (called Laguna Salinas by the Spanish), in northeastern Gaines County, is the largest salt lake on the Texas plains. The county's elevation ranges from 3,000 to 3,600 feet above sea level, and its annual average rainfall is 15.83 inches. The average minimum temperature in January is 16° F; the average maximum in July is 94°. The county has a 210-day growing season. The agricultural components of the local economy earn about $92 million annually from cotton (Gaines County ranks second among cotton-producing counties in Texas), sorghums, vegetables, peanuts, sunflowers, peaches, pecans, cattle, sheep, and hogs. Irrigated land amounts to about 400,000 acres. Gaines County is also one of the state's leading oil counties; it produced 42,810,261 barrels in 1990.
