Ready to uncover a hidden chapter in Austin’s history? The tale of the Texas No Name Number 8 Dam is an exciting story. It is a story of ambition and disaster. It is a story of how Austin learned to live with the Colorado River.
Imagine the late 19th century. Austin is a small town. It dreams of becoming a manufacturing hub. Civic leader Alexander Penn Wooldridge envisions cotton mills lining the riverbanks. Cheap hydroelectricity will fuel this industrial boom.
In 1891, Austin triples its corporate area. The city plans a municipal water and electric system. A dam is constructed for power. Much of the hydroelectric power is leased to manufacturers. The Austin Dam is completed in 1893. It stands sixty feet high. It stretches 1,100 feet long.
Electricity generated by the dam begins powering the city’s streetcar line. It also powers Austin’s water and light systems. The dammed river creates Lake McDonald. It is named for Mayor John McDonald. He championed the project. New residents are attracted to Austin. Developers arrive. People seek respite from the Texas heat in Lake McDonald. Land speculation drives a boom in the mid-1890s.
The Austin Dam was not without its flaws. It was built on the Balcones Fault. Silt began filling Lake McDonald. The dam’s design did not accommodate large volumes of water. The Colorado River’s flow proved inconsistent. The dam never produced steady power. Manufacturers never came to Austin.
Disaster struck on April 7, 1900. A spring storm caused floodwaters to crest eleven feet atop the dam. Two 250-foot sections broke away. The Austin Dam failed. The flood drowned eighteen people. It destroyed 100 houses. The estimated loss was $1.4 million.
Austin recovered. Citizens refused to abandon city-owned electric power. They bought the private power company. It used steam-driven generators. Austin Energy is a legacy of the old Austin Dam.
The city tried to rebuild the dam. A dispute halted repairs in 1912. Another flood damaged it in 1915. The wrecked dam became “a tombstone on the river.” The Lower Colorado River Authority stepped in. They rebuilt it with federal money.
Tom Miller Dam was completed in 1940. Portions of the 1893 and 1912 dams were incorporated. These are now hidden under layers of concrete. Tom Miller Dam was overshadowed by larger dams upstream. These dams formed the Texas Highland Lakes. Lake Travis and Lake Buchanan provide water. They also provide hydroelectric power. Flood control was improved for Central Texas.
The Texas No Name Number 8 Dam is more than ruins. It is a symbol. It is a symbol of Austin’s ambition. It is a reminder of the power of nature. It is a testament to the city’s resilience. It’s a story etched in concrete and flowing water.
