Summary
Completed in 1970, this earth dam stands at a height of 17 feet and spans a length of 1080 feet, creating a storage capacity of 110 acre-feet. The dam serves as a crucial structure for regulating the flow of Arbeka Creek and mitigating flood risks in the area.
Managed by the Oklahoma Water Resources Board, Oknoname 063002 is classified as a low hazard potential dam with a very high risk assessment rating. Despite being in good condition and equipped with a controlled spillway, the dam is not currently rated for its overall condition. With state-mandated inspections, enforcement, and permitting in place, the dam plays a vital role in water resource management and flood control efforts in the region.
Owned and operated by a private entity, Oknoname 063002 is a significant piece of infrastructure within the Tulsa District of Oklahoma. With its primary purpose listed as "Other," the dam stands as a testament to the collaborative efforts between private owners and state regulators to ensure the safety and functionality of water resource systems in the face of changing climate conditions and increasing water management challenges.

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.
