Summary
This earth dam stands at a height of 16 feet and has a hydraulic height of 11 feet, with a length of 300 feet and a storage capacity of 50 acre-feet. Completed in 1940, the dam serves the primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board. It is situated on the TR-ELM CR river and is under the jurisdiction of the state, with inspection, permitting, and enforcement all handled by state agencies.
Despite its low hazard potential, Oknoname 121006 is classified as having a very high risk due to its location and structural characteristics. The dam features a controlled spillway and a single valve outlet gate. While its condition is not currently rated, the dam has an inspection frequency of 5 years, with the last inspection conducted in June 2011. The risk management measures for this dam are not specified, and there is no Emergency Action Plan (EAP) in place. However, the dam meets state regulatory guidelines and is maintained by private owners.
In the event of an emergency, the lack of recent updates to the EAP, inundation maps, and emergency contacts may pose challenges for risk management. With a risk level of 1 on a scale of 1 to 4, careful monitoring and maintenance of Oknoname 121006 are crucial to ensure the safety of surrounding areas. As the dam is not owned or funded by federal agencies, its operations and risk assessment fall solely under state jurisdiction, emphasizing the importance of effective state regulation and enforcement to mitigate potential hazards.

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.
