The Hamburg Flood Control (Pa-476) dam, located in Windsor Township, Berks County, Pennsylvania, was completed in 1965 by the USDA NRCS for the primary purpose of flood risk reduction along the TR Mill Creek. Standing at a height of 46 feet and a length of 400 feet, this earth dam provides a maximum storage capacity of 102 acre-feet to protect the surrounding area from potential flooding events. The dam is regulated and permitted by the Pennsylvania Department of Environmental Protection, ensuring its structural integrity and effectiveness in managing water levels during periods of high discharge.

Managed by the local government, this flood control structure is inspected annually to monitor its condition, with the latest assessment in November 2020 rating its state as fair. With a high hazard potential due to its location and purpose, the Hamburg Flood Control dam plays a crucial role in safeguarding the community against flood risks. While no emergency action plan (EAP) or inundation maps are currently in place, the dam's design and construction by the USDA NRCS demonstrate a commitment to effective flood control measures in the region. As a key component in the flood risk reduction strategy for the area, the Hamburg Flood Control (Pa-476) dam remains a vital asset in protecting against potential water-related disasters.
