Built in 1965 by the USDA NRCS, this earth-type dam stands at a height of 41 feet and serves the primary purpose of flood risk reduction in the Halderman Creek-TR watershed. With a storage capacity of 1750 acre-feet and a drainage area of 6.91 square miles, Frd No 9-2 plays a crucial role in managing water flow and mitigating flood risks in the region.
