Dam and Well
Goldthwaite, Mills County, Texas
Marker Inscription
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.

The Story
When the Gulf, Colorado & Santa Fe Railroad reached the area in 1885, its officials laid out the town of Goldthwaite and built a reservoir to water their steam locomotives. A 25-foot dam impounded several springs into a pond that doubled as a favorite swimming hole, and in 1906 the railroad drilled a deep spring-fed well for still more water. By 1915 the sources fell short and the dam was breached; today those same springs feed a stream through the county park and the old well still serves the city.
Why it matters
The dam and well are a reminder that the steam railroad's constant thirst shaped where and how West Texas towns were founded and watered.
The story behind this marker
AI contextThe era
Railroads remade Texas in the late 1800s. Where tracks went, towns grew up. Where they did not, settlements often faded. Across Central and West Texas, railroad companies did more than lay track: they often decided where a town would stand, surveyed the lots and sold them to settlers.
The Gulf, Colorado & Santa Fe Railroad was one of those builders. It pushed inland from the Gulf Coast into Central Texas and beyond. When it reached this area in 1885, company officials laid out the town of Goldthwaite, giving the place a street grid and a reason to exist.
Steam locomotives had one constant need besides fuel: water. They boiled it into steam and used it up quickly, so railroads needed reliable water stops at regular intervals along the line. In the dry and unpredictable climate of Central Texas, finding and holding enough water was a serious engineering problem. It shaped where towns went and what they built.
People & events
From the start, the railroad planned water into Goldthwaite. Company officials built a reservoir to supply the locomotives. A 25-foot-high dam near this site captured water from several springs and formed a pond, and the pond soon took on a second life. Residents made it a favorite place to swim, so a piece of railroad infrastructure became part of the town's social life.
As train traffic grew, so did the demand for water. In 1906 the railroad dug a 50-foot-deep, spring-fed well at this site to add to the supply. For a while the combination of the springs, the pond and the well was enough to keep the engines running.
By 1915 even that was not enough. The dam was broken and the reservoir drained, ending the swimming-hole era. The springs themselves outlasted the railroad's needs. They still flow as a stream through Mills County Park, and the old well now serves the city, so a water source first tapped for steam engines still supplies the town.
Its place in the American story
Goldthwaite's dam and well are a small example of a nationwide pattern. Across the American West, the steam railroad's need for water helped decide where towns appeared. Water stops became depots, depots became towns, and many towns survive today because a railroad engineer once needed a reliable spring.
The site also shows how company towns and railroad planning shaped the West. Towns like Goldthwaite did not grow slowly from a crossroads. Corporations laid them out on purpose, and their earliest public works were often built for the railroad first and the residents second.
Finally, the story follows a common arc in American infrastructure: something built for one purpose ends up serving another. A reservoir for locomotives became a swimming hole, and a railroad well became part of a city water supply. As railroads changed and steam gave way to diesel, many communities inherited the dams, wells and water systems the railroads left behind.
If you visit
The marker makes the most sense alongside the water itself. The springs that once filled the railroad's reservoir now feed a stream through Mills County Park. Following it lets you connect the marker's story to living water, and you can picture the 25-foot dam and the swimming pond that once stood nearby.
Goldthwaite is a small Central Texas town in rolling ranch and pecan country. Its layout still reflects its railroad beginnings, and a walk near the tracks and through downtown helps you imagine the place in 1885, newly platted and built around the arrival of the trains.
It is an easy stop on a scenic drive through the Hill Country and Central Texas, especially for travelers interested in railroad history. Look for other railroad-era markers in nearby towns to trace how the Gulf, Colorado & Santa Fe line shaped this part of the state.

Mills County State Bank
Goldthwaite, TX
Goldthwaite boomed after the Gulf, Colorado, and Santa Fe Railway reached Mills County, and by 1888 the growing county seat needed a bank—so D.H. Trent opened a private one with a few thousand dollars in deposits. Through decades of reorganization it became the state-chartered Trent State Bank in 1908 and, in 1952, the Mills County State Bank. It marked 120 years in business in 2008, having weathered hard times and expanded into neighboring towns.
Regency Suspension Bridge
Richland Springs, TX
After repeated floods destroyed earlier crossings of the Colorado River here, San Saba and Mills Counties joined forces to build this bridge, named for the Mills County town of Regency, with the Austin Bridge Company of Dallas finishing it in October 1939. Its road deck hangs from two steel cables more than three inches thick, each spun from 475 galvanized wire strands. Restored by the Texas Department of Transportation in 1999, it is one of the last suspension bridges in Texas still open to vehicle traffic.
Site of Lometa Reservoir
Lometa, TX
Lometa began as a railroad town in the mid-1880s, and when a second line arrived in 1909 the railroads needed water for their thirsty steam locomotives. A dam completed in 1911–12 backed up Emory and Salt Creeks into a lake—known as Santa Fe Lake—that watered the trains and doubled as a recreation spot. As diesel engines replaced steam, the need faded, and the reservoir was retired in the 1970s.
Scholten Railroad
Lometa, TX
From about 1912 to 1920, the Scholten Brothers Cedar Company ran a 25-mile narrow-gauge railroad from Lometa into San Saba County, built by Dutch immigrants Edward and Alfred Scholten. The little line hauled cedar posts and piling to the Santa Fe main line at Lometa, feeding the fencing and construction needs of a fast-growing West Texas. At its height the operation employed some 500 workers, with headquarters just west of this spot.
