About Hidden Lake Dam

The dam stands 57 feet tall and stretches 800 feet across, creates a reservoir covering 42 acres, has a maximum storage capacity of 833 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2000, the structure is 26 years 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. The most recent inspection on record was 08/24/2021.

At 57 feet, this dam is taller than 95% of all dams in the United States.
