Completed in 1983, this dam stands at a structural height of 28 feet and stretches 730 feet in length, providing a maximum storage capacity of 173 acre-feet and a normal storage of 90 acre-feet. With a low hazard potential and a very high risk assessment rating, this dam is equipped with a controlled spillway and a single valve outlet gate.
Despite its age, SCS-Cherokee Sandy Site-12 remains in a not rated condition, with the last recorded inspection dating back to January 1980. However, the dam is subject to regular state permitting, inspection, and enforcement, ensuring its continued functionality in mitigating flood risks for the local community. Operated by the Oklahoma Water Resources Board, this dam serves as a crucial infrastructure for water resource management and climate resilience in the region, underlining the importance of maintaining and monitoring its structural integrity for long-term sustainability.
