Summary

Completed in 2001, this stone core dam stands at a height of 29.1 feet and has a storage capacity of 49.25 acre-feet. With a surface area of 4.5 acres and a drainage area of 92 square miles, this dam plays a crucial role in mitigating flood risks in the region.

Managed by the Oklahoma Water Resources Board, Oknoname 30057 is regulated, inspected, and enforced by state agencies to ensure its proper functioning. Despite its low hazard potential, this dam is categorized as having a very high risk due to its critical role in flood control. While its condition is not currently rated, the structure has been deemed to meet safety guidelines for emergency action plans. With a controlled spillway and a maximum discharge capacity of 15.1 cubic feet per second, this dam is instrumental in protecting the surrounding area from potential flooding events.

Overall, Oknoname 30057 stands as a testament to the collaborative efforts between private owners and state agencies in managing water resources and climate-related risks. With its strategic location and design for flood risk reduction, this dam serves as a vital piece of infrastructure in safeguarding the community of Kingfisher and ensuring the sustainability of the surrounding environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
