About Lake Of The Oaks Dam

The primary purpose of Lake Of The Oaks Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Ben Knapp (private). It impounds the Tr-buck Run Cr near St Patrick.

The dam stands 34 feet tall and stretches 990 feet across, creates a reservoir covering 65 acres, has a maximum storage capacity of 2,141 acre-feet, and collects water from a drainage area of 900 square miles. Completed in 1962, 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. The most recent inspection on record was 08/13/1990. That was 35 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 34 feet, this dam is taller than 80% of dams nationwide.
