Lake Quinn, located in South Canaan Township, Pennsylvania, is a privately owned reservoir primarily used for recreational purposes. Constructed in 1946, the earth dam stands at 12 feet tall and spans 150 feet in length, providing a normal storage capacity of 421 acre-feet. The reservoir covers 118 acres with a drainage area of 9.7 square miles, fed by the Middle Creek tributary.

Despite its picturesque setting, Lake Quinn poses a high hazard potential due to its poor condition assessment. The dam's spillway, an uncontrolled type with a width of 148 feet, is a crucial component in managing water levels during peak discharge. The Pennsylvania Department of Environmental Protection regulates the dam, ensuring periodic inspections and enforcement to mitigate risks and maintain public safety.

With its moderate risk assessment rating, Lake Quinn serves as a valuable recreational resource for the local community, offering opportunities for fishing, boating, and other water-based activities. However, ongoing maintenance and risk management measures are essential to safeguard the dam's integrity and preserve the reservoir's environmental and recreational value in the face of changing climate conditions.
