Tuesday marks a significant anniversary for an Austin landmark which has defined the city’s character and protected it from flood waters.

It was 70 years ago that the Tom Miller Dam began operations. It's part of the Lower Colorado River Authority's network of dams.



The year 1900 marked a golden age for Austin. The city’s first dam was built where Tom Miller dam stands now.  LCRA spokesperson John Williams says it created a buzz of innovation at the time. The hydroelectricity it generated powered moon towers to light the city at night and to run electric trolleys.

“One part of which brought folks to the lake where they could go out and ride paddle boats and watch diving exhibitions,” said Williams.

Those good times came to a sad and tragic end 110 years ago when a flash flood triggered a devastating wall of water. Eighteen people died and 100 homes were destroyed.

Yet, the city forged ahead with a second Austin dam built at the same location in 1912.

The work was almost complete in 1915 when another flood left this gaping hole behind. As a result of the flood, the dam went unrepaired for more than two decades.

In 1940, the city and LCRA dedicated Tom Miller Dam, and it’s played a huge part in Austin’s history ever since.

“It gives the whole central city its character in addition to protecting us from periodic flooding,” said Austin City Council member Chris Riley.

The dam protects the City of Austin from flooding, and it created Lady Bird Lake and Lake Austin.

“It’s nice to have a good place to swim and kayak,” said Jeff Crawford who frequents Lady Bird Lake with his three dogs.
