This dam, with a height of 30 feet and a hydraulic height of 27 feet, primarily serves the purpose of flood risk reduction along TR-Cherokee Sandy Creek. With a storage capacity of 128 acre-feet and a surface area of 4 acres, this structure plays a crucial role in managing water resources in Garvin County.
Despite being classified as having a low hazard potential, SCS-Cherokee Sandy Site-10 is rated as having a very high risk due to its condition assessment being labeled as "Not Rated." The dam features a controlled spillway and a valve outlet gate, with a maximum discharge capacity of 635 cubic feet per second. While the last inspection date was recorded in 1980, the dam is scheduled for inspections every five years to ensure its structural integrity and functionality for flood control. With the potential for future modifications and improvements, this site remains a focal point for water resource and climate enthusiasts seeking to understand and mitigate flood risks in the region.
