The dam, with a height of 70 feet and a length of 800 feet, serves to mitigate flooding along the Smith Hollow river or stream. With a storage capacity of 1005 acre-feet and a maximum discharge of 1920 cubic feet per second, this dam plays a crucial role in protecting the surrounding area from potential hazards.
Despite being last inspected in 1980 and not currently rated for condition assessment, the SCS-Sallisaw Creek Site-27 is categorized with a high hazard potential and very high risk assessment. It is equipped with a controlled spillway and a single valve outlet gate. As a significant flood control infrastructure in Sequoyah County, this dam represents a vital component in the water resource management and climate resilience efforts in the region. Future inspections and risk management measures will be essential to ensure the continued safety and effectiveness of this important structure.
