It has a maximum storage capacity of 90 acre-feet and a normal storage capacity of 30 acre-feet. The dam spans 900 feet in length and is situated on the TR-ROCK CR river/stream.
Despite its low hazard potential, Cavanal is considered to have a very high risk due to its condition assessment being "Not Rated." The dam has one valve outlet gate and a controlled spillway with a width of 1 foot. The inspection frequency for Cavanal is every 5 years, with the last inspection taking place in January 2010. The dam is under the regulatory jurisdiction of the Oklahoma Water Resources Board (OWRB) and has state permitting, inspection, and enforcement in place.
Overall, Cavanal presents an intriguing case study for water resource and climate enthusiasts due to its unique design and risk profile. The dam's location in Le Flore County, Oklahoma, and its association with the Tulsa District of the US Army Corps of Engineers add to its significance. As efforts to manage and mitigate risks associated with dams continue to evolve, Cavanal serves as a notable example of the complexities involved in ensuring the safety and sustainability of water infrastructure.
