Built in 1902, this gravity dam stands at a height of 41 feet and stretches 610 feet in length, providing a storage capacity of 345 acre-feet. With a controlled spillway width of 500 feet and a maximum discharge of 93,945 cubic feet per second, this structure serves multiple purposes including hydroelectric power generation and navigation.
Managed by the Federal Energy Regulatory Commission, the Fries dam has a high hazard potential and is categorized as very high risk, emphasizing the need for regular inspections and risk management measures. While the dam's condition assessment is currently unavailable, emergency action plans have been prepared, last revised in January 2021. The surrounding area is at risk of inundation during a potential breach, highlighting the importance of proactive monitoring and preparedness.
Fries dam's historical significance and crucial role in water resource management make it a focal point for water resource and climate enthusiasts. As a key structure in the Wilmington District, its impact on the local environment and community underscores the importance of sustainable dam operations and maintenance practices to ensure safety and resilience in the face of changing climate conditions.
