Rockhouse Creek Dam

About Rockhouse Creek Dam

The primary purpose of Rockhouse Creek Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Logan County Commission (local government). It impounds the Rockhouse Creek near Mifflin.

The dam stands 58 feet tall and stretches 320 feet across, has a maximum storage capacity of 425 acre-feet, and collects water from a drainage area of 2 square miles.

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 03/31/2025.

At 58 feet, this dam is taller than 95% of all dams in the United States.
