Altus, also known as Lake Altus, is a federal-owned water resource located in Kiowa County, Oklahoma. Managed by the Bureau of Reclamation, this concrete gravity dam was completed in 1945 and serves the primary purpose of flood risk reduction along the North Fork Red River. With a structural height of 110 feet and a storage capacity of 162,526 acre-feet, Altus covers a surface area of 7,170 acres and has a maximum discharge of 57,100 cubic feet per second.

The dam's high hazard potential and very high risk assessment underscore the importance of its management and maintenance. While not currently regulated or inspected by state agencies, Altus undergoes regular inspections by the Bureau of Reclamation. The dam is equipped with a controlled spillway and a single valve outlet gate for water release. In case of emergencies, an Emergency Action Plan is in place, ensuring preparedness for potential risks and disasters.

Altus plays a crucial role in water resource management and flood control in the region, providing essential protection to downstream communities. Its strategic location in the Tulsa District and its significant storage capacity make it a vital asset for water supply and risk mitigation efforts. As climate change continues to impact water resources, the careful monitoring and maintenance of dams like Altus are essential to ensure their continued effectiveness and safety for years to come.
