About Josephine
The primary purpose of Josephine is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Mccain Foods Usa, Inc. (private). It impounds the Tr Prestile Stream near Easton.
The dam stands 31 feet tall and stretches 3,100 feet across, creates a reservoir covering 220 acres, has a maximum storage capacity of 2,800 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1967, 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. Its condition is rated unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. An emergency action plan is in place for this dam. The most recent inspection on record was 05/11/2022.
