Pa-483, located in Washington, Pennsylvania, is a vital infrastructure designed by the USDA NRCS for flood risk reduction along Ward Run. Completed in 1973, this earth dam stands at a height of 74 feet and spans 360 feet, providing a storage capacity of 523 acre-feet for water management. With a satisfactory condition assessment and a high hazard potential, Pa-483 is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections to ensure its structural integrity.

Managed by the local government, Pa-483 plays a crucial role in protecting the surrounding community from potential flooding events. The dam's primary purpose is flood risk reduction, and it has successfully served this function for decades. Its design, incorporating buttress core types and unlisted/unknown foundations, highlights its resilience and effectiveness in managing water flow and storage in the region.

Despite being a non-USACE structure, Pa-483 is a key component of the water resource infrastructure in the area, providing essential flood control measures and contributing to the overall safety and well-being of the residents. As climate change continues to impact weather patterns, structures like Pa-483 play a critical role in mitigating the risks associated with extreme precipitation events and ensuring the sustainable management of water resources for future generations.
