Hoopes Dam, located in Wooddale, Delaware, is a concrete gravity dam on the Red Clay Creek-TR river, serving as a crucial water supply source in New Castle County. Built in 1932 and standing at a structural height of 127 feet and a length of 840 feet, the dam has a storage capacity of 9068 acre-feet, with a normal storage level of 6730 acre-feet. The dam underwent several modifications over the years, including structural and hydraulic upgrades in 1979, 1982, 2008, and 2020 to ensure its continued functionality and safety.
Managed by the local government and regulated by the Delaware Department of Natural Resources and Environmental Control (DNREC), the Edgar M. Hoopes Dam is classified as a high hazard structure with a satisfactory condition assessment. Despite its moderate risk profile, the dam has not experienced any major incidents and meets the necessary safety guidelines. Its uncontrolled spillway, with a width of 28 feet, provides an essential safety feature in case of excess water flow, with a maximum discharge capacity of 2668 cubic feet per second.
With its rich history, strategic location, and vital role in water supply management, the Edgar M. Hoopes Dam stands as a testament to engineering excellence and environmental stewardship. Its continuous monitoring, inspection frequency, and adherence to regulatory standards ensure the safety and reliability of this essential water resource infrastructure in Delaware. For water resource and climate enthusiasts, the dam serves as a fascinating example of sustainable water management practices and the critical role of dams in ensuring water security for communities and ecosystems.
