About Patton Park Lake Dam
The primary purpose of Patton Park Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Patton Park Incorporated (private). It impounds the Lambs Creek.
The dam stands 28 feet tall and stretches 550 feet across, creates a reservoir covering 97 acres, has a maximum storage capacity of 1,954 acre-feet, and collects water from a drainage area of 15 square miles. Completed in 1935, the structure is well-established, with more than 75 years of service.
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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 11/29/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
