Summary
Built in 1965, this earth dam stands at a height of 20 feet with a length of 960 feet, serving a primary purpose that is classified as "Other." The dam has a storage capacity of 100 acre-feet and a normal storage level of 60 acre-feet, with a low hazard potential and a very high risk assessment rating.
Situated on TR-Campbell Creek in Kingfisher County, Oknoname 073006 is equipped with a controlled spillway and a single valve outlet gate. While the dam has not been officially rated for its condition, it undergoes inspections every five years, with the last inspection taking place in January 2010. The surrounding area, with a surface area of 9 acres, faces a very high risk level associated with the dam, highlighting the importance of ongoing risk management measures to ensure the safety and resilience of the structure and the community it serves.
Despite its low hazard potential, the risk assessment for Oknoname 073006 deems it as very high, emphasizing the need for proactive emergency preparedness and potential risk mitigation strategies. With its unique features and location in an area of high risk, this dam serves as a focal point for water resource and climate enthusiasts interested in understanding the complexities of managing and safeguarding critical infrastructure in the face of evolving environmental 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.
