About White Lake Dam
The primary purpose of White Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Myfe Moore (private). It impounds the Tr-san Geronimo Creek.
The dam stands 42 feet tall and stretches 725 feet across, creates a reservoir covering 19 acres, and has a maximum storage capacity of 420 acre-feet. Completed in 1970, the structure is well into its service life at over 50 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. An emergency action plan is in place for this dam. The most recent inspection on record was 01/12/2011. That was 15 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 42 feet, this dam is taller than 89% of dams nationwide.
