Forest Lake, located in Susquehanna, Pennsylvania, is a privately owned dam with a primary purpose of recreation. Built in 1842, this Earth dam stands at a height of 12 feet and a length of 200 feet, creating a reservoir with a storage capacity of 720 acre-feet. The dam is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its safety and compliance with state regulations.

With a surface area of 46 acres and a drainage area of 0.84 square miles, Forest Lake offers a picturesque setting for outdoor enthusiasts to enjoy activities such as fishing, boating, and wildlife observation. The dam's spillway type is uncontrolled, with a width of 3 feet, and it has a significant hazard potential due to its age and condition. Despite this, the dam is currently rated as satisfactory in its condition assessment, with a moderate risk level.

In 2004, Forest Lake underwent hydraulic modifications, and it is important for water resource and climate enthusiasts to monitor the dam's risk management measures and emergency preparedness plans. With its rich history and recreational opportunities, Forest Lake serves as a valuable resource for the local community and a reminder of the importance of maintaining and managing water infrastructure in a sustainable manner.
