No 5
No 5 is an earth dam located in Lackawanna County, Pennsylvania, built in 1888. It carries a High hazard potential classification and has a poor condition assessment.
About No 5
The primary purpose of No 5 is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by County Of Lackawanna (local government). It impounds the Stafford Meadow Brook.
The dam stands 35 feet tall and stretches 248 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 206 acre-feet, and collects water from a drainage area of 12 square miles. Completed in 1888, the structure is over a century 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 05/26/2020.
At 35 feet, this dam is taller than 82% of dams nationwide.
