Lcra Inks Dam is a gravity dam located in Burnet County, Texas, built in 1938. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Lcra Inks Dam
The primary purpose of Lcra Inks Dam is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Lower Colorado River Authority (local government). It impounds the Colorado River near Marble Falls.
The dam stands 97 feet tall and stretches 1,550 feet across, creates a reservoir covering 803 acres, has a maximum storage capacity of 63,500 acre-feet, and collects water from a drainage area of 31,290 square miles. Completed in 1938, the structure is well-established, with more than 75 years of service.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 10/06/2022.
At 97 feet, this dam is taller than 98% of all dams in the United States.
