Rocky Glen is a privately owned dam located in Lackawanna, Pennsylvania, specifically in Moosic Borough. Built in 1903, this gravity dam stands at a height of 19 feet and stretches 350 feet in length, holding a storage capacity of 281 acre-feet. The dam serves primarily for recreational purposes, with a surface area of 37 acres and a drainage area of 1.5 square miles, impounding the waters of Dry Valley Run.

Despite its historical significance, Rocky Glen poses a high hazard potential due to its poor condition assessment. The Pennsylvania Department of Environmental Protection regulates and inspects this dam, ensuring compliance with safety standards. With a last inspection date in April 2020 and an inspection frequency of once per year, ongoing monitoring and maintenance are crucial to mitigate any potential risks of failure and protect the surrounding community.

Enthusiasts of water resources and climate conservation should take note of Rocky Glen's significance as a recreational structure with a rich history dating back over a century. As efforts continue to maintain and improve the dam's condition, its role in water management and public safety underscores the importance of sustainable infrastructure practices in the face of evolving climate challenges.
