Located in a region where native Comanches, Mescalero, and Lipan Apache Indians once roamed, Monahans' history as a community extends back to the late 1880s with the expansion of the Texas and Pacific Railway across the South Plains. For the few people living in West Texas, the building of a transcontinental railroad through the area meant the arrival of civilization. In the summer of 1881, Texas and Pacific Railroad contracted with surveyor John Thomas Monahan, who discovered that the lack of water for the laying crew and their animals would slow down construction of the rail. Monahan's digging of a water well produced an abundance of good water ( a day) and was instrumental in the success of the city. Prior to this solution, water had to be hauled to the area from Big Spring, Texas.
