About Lake Mcqueeney Dam

The primary purpose of Lake Mcqueeney 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 Guadalupe-blanco River Authority (state). It impounds the Guadalupe River near Mcqueeney.

The dam stands 42 feet tall and stretches 1,555 feet across, creates a reservoir covering 396 acres, has a maximum storage capacity of 6,170 acre-feet, and collects water from a drainage area of 1,697 square miles. Completed in 1928, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 02/06/2024.

At 42 feet, this dam is taller than 88% of dams nationwide.
