Summary

Built in 1960, this earth dam stands at a height of 21 feet and has a storage capacity of 70 acre-feet, with a normal storage of 50 acre-feet. Its spillway, controlled in nature, boasts a width of 1 foot, ensuring efficient water discharge during times of excess.

Despite its low hazard potential, Oknoname 075017 is subject to state regulation and inspection by the Oklahoma Water Resources Board (OWRB), ensuring its structural integrity and safety for the surrounding community. The dam's risk assessment categorizes it as having a very high risk level (1), prompting the need for effective risk management measures to mitigate potential dangers. With a designated emergency action plan (EAP) status unclear, there is a need for updated emergency protocols and communication strategies to enhance preparedness in case of any unforeseen incidents.

Owned by a private entity, Oknoname 075017 not only supports water storage and flood control functions but also plays a significant role in the local ecosystem. With its critical location and historical significance, this dam stands as a testament to human ingenuity in managing water resources amidst a changing climate landscape.

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.
