Thomas is a private dam located in Monroe County, Pennsylvania, with a primary purpose of recreation. Built in 1982, this earth dam stands at a height of 10 feet and stretches 400 feet in length, creating a storage capacity of 13 acre-feet. Situated on the TR Stony Run river, Thomas is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure compliance with state requirements.

Despite its recreational function, Thomas poses a significant hazard potential with a poor condition assessment. In 2016, it underwent hydraulic modifications to address safety concerns. With a drainage area of 0.69 square miles and a surface area of 1.8 acres, this dam plays a crucial role in managing water resources in the region. Its last inspection in March 2020 highlighted the need for continued monitoring and maintenance to prevent any potential risks to downstream communities.

As water resource and climate enthusiasts, understanding the importance of maintaining infrastructure like Thomas is vital for ensuring the safety and sustainability of our water systems. By staying informed about the regulatory oversight, condition assessments, and risk management measures associated with dams like Thomas, we can contribute to the preservation of our natural resources and the protection of our communities from potential hazards.
