Summary
It stands at a height of 15 feet and has a hydraulic height of 11 feet, serving as a crucial structure for regulating the flow of the North Fork Red River. With a normal storage capacity of 109 acre-feet and a maximum storage of 129 acre-feet, this dam plays a significant role in water resource management in the region.
Despite being classified as low hazard potential, Oknoname 065002 is deemed 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. While the dam has not been modified in recent years, it is subject to regular inspections every five years. The dam is state regulated by the Oklahoma Water Resources Board (OWRB) and is under state jurisdiction, with permitting, inspection, and enforcement responsibilities falling under state authority.
Overall, Oknoname 065002 serves as a vital component in the water infrastructure of Oklahoma, providing essential flood control and water storage capabilities. With its strategic location in the Mavajo Mountains and its role in regulating the North Fork Red River, this dam underscores the importance of sustainable water resource management in the face of climate change and increasing water demands. As efforts continue to monitor and maintain the dam's integrity, it remains a key asset in safeguarding the local community and environment from potential water-related risks.

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.
