Gaines County is a county in western Texas noted for its wide plains and rural communities. According to the 2010 U.S. census the county had 17,526 residents; the county seat is the city of Seminole. The county lies on the high plains region of Texas and plays a role in both agriculture and energy production that characterize much of the surrounding area.

Geography and climate

The landscape of Gaines County is largely flat to gently rolling, part of the southern High Plains that extend across this portion of the state. The climate is semi‑arid with hot summers and cool winters, and precipitation is generally low and variable. Local water supplies and irrigation practices influence land use; for regional maps and basic geographic information see maps and data.

History

Before Euro‑American settlement, the area was used by Native American groups and later by cattle ranchers. The county was created in the early 20th century and named for U.S. Army officer Edmund P. Gaines. Settlement and development accelerated with dryland farming, the introduction of irrigation, and later oil and gas exploration, all of which shaped local towns and infrastructure.

Economy and communities

The local economy mixes agriculture and energy. Major agricultural activities include irrigated and dryland farming—cotton and grain crops—and cattle ranching. Energy production, particularly oil and natural gas from the greater Permian Basin, has been an important source of jobs and revenue in recent decades. Principal communities include the county seat, Seminole, and other small towns such as Seagraves and surrounding rural settlements; community profiles are available at local profiles.

Government, services and points of interest

County government is based in Seminole, where the courthouse and administrative offices provide services to residents across a large rural area. Education, healthcare, and transportation services are arranged around small municipal centers and county facilities. Visitors and residents often note the region’s open skies, agricultural landscapes, and the economic role it plays within the broader West Texas energy corridor; official information can be found through county pages and public records at official links.
