Structure #11-15, also known as the Brevard-Ross Dam, is a local government-owned earth dam designed by the USDA NRCS. Completed in 1994, this structure serves the primary purpose of flood risk reduction along the Scrub Grass Branch (Sw Fk) river or stream. With a hydraulic height of 27.3 feet and a structural height of 44.6 feet, the dam has a normal storage capacity of 7 acre-feet and a maximum storage of 38.5 acre-feet, covering a surface area of 1.25 acres within a drainage area of 195 square miles.
The dam poses a high hazard potential, with a satisfactory condition assessment as of April 2018. Inspected every 2 years, the Brevard-Ross Dam meets state-regulated standards enforced by the NCDEQ Dam Safety Program. Despite its moderate risk assessment rating of 3, the dam has not been modified in recent years and operates with uncontrolled spillways and outlets. In case of an emergency, the dam's emergency action plan (EAP) and risk management measures are in place, ensuring the safety and protection of the surrounding area from potential inundation events.
With its strategic location and vital role in flood risk reduction, the Brevard-Ross Dam stands as a crucial infrastructure in McDowell County, North Carolina. Managed by local government authorities and designed by USDA NRCS, this earth dam serves as a safeguard against potential flooding along the Scrub Grass Branch, demonstrating a commitment to water resource management and climate resilience in the region.
