Tioga Dam-Mansfield Levee, located in Tioga, Pennsylvania, along the Tioga River, serves as a critical flood risk reduction structure designed and managed by the US Army Corps of Engineers. Completed in 1979, this rockfill dam stands at 29 feet in height and spans 11,740 feet in length, with a primary purpose of flood risk reduction for the surrounding area. Despite its high hazard potential, the levee system plays a vital role in reducing the risk of flooding to the borough of Mansfield. However, it is crucial to note that while the Mansfield Levee mitigates flood risk, it does not eliminate it entirely, as catastrophic flooding could still occur under extreme circumstances such as rare rainfall events or unexpected seepage leading to a breach of the levee.

To manage and reduce the risk associated with the Mansfield Levee, the US Army Corps of Engineers implements rigorous risk management measures. This includes regular inspections, maintenance, and monitoring of the levee system, with increased scrutiny during high water events. The Corps also continually updates the Emergency Action Plan and conducts emergency response exercises with federal, state, and local authorities to ensure preparedness for potential flood events. By closely monitoring weather forecasts and coordinating with relevant agencies, the USACE remains proactive in providing flood warnings and safeguarding the community of Mansfield from the devastating impacts of uncontrolled floodwaters.
