Memorial Lake, located in Lebanon, Pennsylvania, is a state-owned recreational reservoir that was completed in 1946. With a dam height of 37 feet and a length of 760 feet, the lake offers a surface area of 87 acres and a drainage area of 7.9 square miles. The primary purpose of Memorial Lake is recreation, providing visitors with opportunities for fishing, boating, and picnicking in a picturesque natural setting.

Despite its recreational appeal, Memorial Lake has been assessed as having a high hazard potential and poor condition. The dam was last inspected in May 2020, with a yearly inspection frequency. In 2002, structural modifications were made to the dam. The Pennsylvania Department of Environmental Protection regulates the dam and is responsible for permitting, inspecting, and enforcing safety measures to ensure the protection of the surrounding community and the environment.

Water resource and climate enthusiasts will be drawn to Memorial Lake for its historical significance, diverse recreational opportunities, and the ongoing efforts to maintain its safety and integrity. The reservoir's location along Indiantown Run offers a unique ecosystem and water source for wildlife and vegetation. As discussions around climate change and water resource management continue, Memorial Lake serves as a valuable case study for balancing recreational use with environmental stewardship and safety considerations.
