Designed by the USDA NRCS, this earth dam serves multiple purposes including fire protection and as a stock or small fish pond. With a hydraulic height of 21 feet and a structural height of 26 feet, the dam has a hazard potential rated as high and a poor condition assessment.
The dam, with a storage capacity of 11 acre-feet and a drainage area of 60 acres, features an uncontrolled spillway and outlet gates. Despite its critical role in providing fire protection and water storage, the dam's condition raises concerns with a risk assessment rating it as moderate (3). The last inspection in January 2021 highlighted the need for maintenance and potentially increased oversight to ensure the safety and reliability of the structure for both water resource management and climate-related purposes.
With the dam being regulated and inspected by the NCDEQ Dam Safety Program, it is essential for stakeholders and water resource enthusiasts to stay updated on any developments or improvements to mitigate risks associated with this crucial infrastructure. As climate change continues to impact water resources, the proactive management and maintenance of structures like Benfield Dam are vital for ensuring the resilience and sustainability of our water systems in the face of evolving environmental challenges.
