About Earl Park
The primary purpose of Earl Park is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Bia (federal). It impounds the Eagle Creek near Lower Log Campground.
The dam stands 38 feet tall and stretches 400 feet across, creates a reservoir covering 49 acres, has a maximum storage capacity of 1,308 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1961, 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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 10/22/2020.
At 38 feet, this dam is taller than 85% of dams nationwide.
