Summary
It serves the primary purpose of debris control along an unnamed tributary to Bull Creek. This dam stands at a height of 20 feet with a hydraulic height of 22.5 feet and a structural height of 23 feet. It has a storage capacity of 50 acre-feet and a drainage area of 0.07 square miles.
Despite its low hazard potential, Oknoname is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, permitting, and enforcement. The dam has a normal storage capacity of 31 acre-feet and covers a surface area of 4.5 acres. The maximum discharge rate for Oknoname is 11.2 cubic feet per second, ensuring effective water management and flood control measures in the region.
Although Oknoname's condition assessment is currently not rated, it is maintained and inspected every 5 years to ensure its structural integrity and safety. With its vital role in debris control and water resource management, this dam plays a significant role in safeguarding the environment and communities in the area, making it an essential structure for water resource and climate enthusiasts to monitor and study.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
