Saffold Dam
Seguin, Guadalupe County, Texas
Marker Inscription
Named for William Saffold, who owned land here in the mid-1800s, Saffold Dam is typical of many mill dams built during the late 19th and early 20th centuries. Originally a natural rock outcropping, the dam was first improved by Henry Troell in the late 1800s when he added rock to the dam to raise the water level to power a cotton gin. The city of Seguin bought Troell's property in 1907 to further develop the river's hydroelectricity, and subsequent improvements have led to the establishment of a hydroelectric plant on the dam's south side.

The Story
Named for landowner William Saffold, this dam on the Guadalupe River began as a natural rock outcropping. In the late 1800s Henry Troell built it up with added rock to raise the water level and power a cotton gin, a classic small-scale mill dam of its day. Seguin bought the property in 1907 to develop the river's power, and later improvements grew into a hydroelectric plant on the dam's south side.
Why it matters
Saffold Dam charts the evolution of American water power — from a gin-turning mill dam of the frontier economy to municipal hydroelectricity in the new industrial century.
The story behind this marker
AI contextThe era
In the second half of the 1800s, much of Texas ran on cotton. Farmers grew it, and every community needed a cotton gin to separate the fiber from the seeds before the crop could be baled and sold. Powering those gins, along with grist mills and saws, was a constant challenge.
Before electricity reached rural areas, moving water was one of the most dependable sources of power. Across the country, people built mill dams to raise a river's level and send water through wheels or turbines. Many were simple structures that took advantage of natural rock ledges in a riverbed.
By the early 1900s, a new idea was spreading quickly: using that same water power to make electricity. Towns and cities across America began building hydroelectric plants, some of them on the sites of older mill dams.
Saffold Dam stands right at the meeting point of those two eras: the old frontier economy of cotton and mills, and the new century of electric power.
People & events
The dam takes its name from William Saffold, who owned land here in the mid-1800s. The marker doesn't tell us more about him, but his name stayed attached to the spot long after he did.
Originally there was no built dam at all, just a natural rock outcropping across the river. In the late 1800s Henry Troell saw its potential. He added rock to raise the water level, creating enough force to power a cotton gin. It was practical engineering, using what nature had already started.
The next chapter belonged to the city of Seguin. In 1907 the city bought Troell's property to further develop the river's hydroelectric potential. It was a bold move for a small Texas city at a time when electric power was still new and exciting.
Later improvements turned the dam into the site of a hydroelectric plant on its south side. A rock ledge that once turned a cotton gin ended up helping to light a town.
Its place in the American story
Saffold Dam tells, in one place, the story of how America powered itself. In the 1800s, thousands of small mill dams across the country turned grinding stones, saws, and gins. They were the backbone of local economies before electricity.
In the early 1900s, many communities embraced hydroelectricity, and city-owned power became a point of local pride and independence. Seguin's purchase in 1907 belongs to that larger movement, which helped bring modern conveniences to small-town America.
The dam also reflects how Texas changed from a frontier cotton economy toward a more modern, industrial one. The same river, and the same rock ledge, served both worlds.
If you visit
Water is the star here. Listen to it flow over the dam and imagine what that steady force meant to people who had no other reliable source of power. If the light is right, look for the rock at the heart of the structure, a reminder that it all began as a natural ledge.
Seguin is an easy stop between San Antonio and Austin, and its riverside setting makes this a pleasant break on a central Texas road trip. Pair it with time in town to explore Seguin's older streets and its long history.
For families, this is a great spot to talk about energy: where electricity comes from, and how people did their work before they had it. Stay safely back from the water and the dam itself, since currents around dams can be dangerous.

Henry Troell
Seguin, TX
A young immigrant from Wichmannshausen, Germany, Henry Troell settled near Seguin before 1860 and, after service in the Confederate Army, parlayed a freighting business into a web of local enterprises. His dam and grist mill on this site grew into something remarkable for a small Texas town — he added hydroelectric generation and, in the 1890s, gave the city its first municipal water and electric systems.
Moore House
Seguin, TX
John Moore, an Irish-born newspaperman and civic leader, settled in Seguin and, through family ties, counted Theodore Roosevelt among his friends. In 1895 he built a modest three-room house here, then in 1900 commissioned a fine Queen Anne residence that wrapped the earlier structure inside it. His descendants carried on, including a son who served as Seguin's mayor for twenty-two years.
Sebastopol
Seguin, TX
Built in 1854–56 by Joshua W. Young, this Greek Revival house rose from an early form of concrete called limecrete—unreinforced, load-bearing walls cast from lime, sand, and gravel. Joseph Zorn, Jr., who served as mayor of Seguin from 1890 to 1910, bought the house in 1874, and it stayed in his family until 1961. It stands among the town's many concrete structures as a notable survivor of early concrete technology in the Southwest.
Joseph Sonka House
Seguin, TX
Joseph Sonka left Czech-speaking Central Europe and reached Seguin in 1878, bringing a stonemason's skill to a growing Texas town. He ran a brickyard and cotton gin, and beginning in 1881 he spent more than a decade building this Italianate-trimmed brick home from his own bricks, finishing it the year he married Annie Klicka. For two years the house even served as a community hospital before settling into generations of Sonka family life.
