Bull Run
Bull Run is an earth dam located in Westmoreland County, Pennsylvania, built in 1934. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Bull Run
The primary purpose of Bull Run is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by City Of Jeannette (local government). It impounds the Bull Run.
The dam stands 44 feet tall and stretches 520 feet across, creates a reservoir covering 20 acres, has a maximum storage capacity of 383 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1934, 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 09/20/2019.
At 44 feet, this dam is taller than 90% of dams nationwide.
