About Clear Lake
The primary purpose of Clear Lake 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 Public Service Company Of Colorado (public utility). It impounds the South Clear Creek near Georgetown.
The dam stands 19 feet tall and stretches 150 feet across, creates a reservoir covering 26 acres, has a maximum storage capacity of 1,100 acre-feet, and collects water from a drainage area of 15 square miles. Completed in 1908, the structure is over a century old.
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 08/30/2022.
