Stoner's Lonesome Lake Dam

About Stoner's Lonesome Lake Dam

The primary purpose of Stoner's Lonesome Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Stoner Properties Llc (private). It impounds the Unnamed Tributary Henderson Creek.

The dam stands 55 feet tall and stretches 400 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 74 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1999, the structure is 27 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. 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 06/29/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.

At 55 feet, this dam is taller than 94% of dams nationwide.
