Summary

Built in 1971, this earth dam stands at a height of 35 feet and stretches 400 feet in length, with a storage capacity of 140 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is subject to state inspection, enforcement, and permitting requirements to ensure its safety and compliance with regulations.

Despite its low hazard potential, Oknoname 113022 has been classified as having a very high risk due to its condition assessment not being rated. The dam's emergency action plan status, inundation maps, and risk management measures are currently unknown. The dam has one outlet valve and a controlled spillway with a width of 1 foot. The last inspection date was in September 2011, with a recommended inspection frequency of every 5 years to monitor its condition and address any potential risks.

Water resource and climate enthusiasts interested in the infrastructure of dams and their regulation in Oklahoma may find Oknoname 113022 to be a compelling case study. With its unique design features and regulatory oversight by the OWRB, this dam serves as a crucial component of water management in the area. However, the lack of recent condition assessments and emergency preparedness plans highlight the importance of continued monitoring and risk management to ensure the safety and integrity of this structure for years to come.

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.
