When the Gulf, Colorado & Santa Fe Railroad reached this area in 1885, company officials platted the town of Goldthwaite and built a reservoir to supply water for steam locomotives. A 25-foot-high dam near this site stored water from several springs, creating a pond that became a favorite swimming spot. The railroad dug a 50-foot-deep, spring-fed well at this site in 1906 to provide more water. In 1915, when these sources became inadequate, the dam was broken and reservoir drained. Today the springs form a stream which runs through Mills County Park, and the well is used by the city.
