About Bishop Lake Dam
The primary purpose of Bishop Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Bishop Lake Civic Association (private). It impounds the Bishop Creek.
The dam stands 27 feet tall and stretches 375 feet across, creates a reservoir covering 24 acres, has a maximum storage capacity of 399 acre-feet, and collects water from a drainage area of 650 square miles. Completed in 1945, 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 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 02/09/2016. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
