Lamesa is the seat of Dawson County at the southeast edge of the Texas High Plains, which are the southernmost extension of the Great Plains of the United States. Its name derived from Spanish "la mesa," meaning "the table," describes the flat terrain. The area economy is based on extensive oil, industrial and agricultural production, and Dawson is one of the state's largest cotton-producing counties.
Nearby lakes have game fishing and water sports. Two golf courses, swimming pool and acres of public parks provide recreation and entertainment.
