Constructed in 1965 by the Tennessee Valley Authority (TVA), the dam stands at a height of 34 feet and has a length of 1890 feet. Its primary purpose is flood risk reduction, but it also serves for irrigation and recreation. The dam has a storage capacity of 7100 acre-feet, with a normal storage level of 5510 acre-feet and a surface area of 447 acres.
Managed and regulated by the TVA, Dogwood Dam features an uncontrolled spillway with a width of 200 feet and outlet gates for controlled water release. The dam has a significant hazard potential and undergoes inspections every two years to ensure its structural integrity. While its risk assessment is moderate, the dam lacks detailed risk management measures and emergency action plans. Despite these challenges, Dogwood Dam remains a vital structure for water resource management in the region and a key player in mitigating flood risks along Big Creek.
