Township Line is a privately owned dam located in Unity Township, Pennsylvania, along Township Line Run. Built in 1900 for recreational purposes, this earth dam stands at a height of 56 feet and spans a length of 790 feet. With a maximum storage capacity of 1250 acre-feet and a normal storage of 750 acre-feet, the dam covers a surface area of 33 acres and serves a drainage area of 0.58 square miles.

Despite its historic significance and recreational value, Township Line dam poses a high hazard potential and is currently in poor condition. The Pennsylvania Department of Environmental Protection regulates this structure, conducting inspections annually to ensure its safety and compliance with state standards. However, the dam's condition assessment remains poor, indicating a need for immediate attention and potential risk management measures to mitigate any potential hazards.

Given its critical role in water resource management and the surrounding community's safety, Township Line dam requires close monitoring and maintenance to prevent any potential failures or emergencies. With its outdated infrastructure and high hazard potential, stakeholders must work together to address the dam's poor condition and implement necessary risk management measures to ensure the safety and security of the area.
