Summary
With a height of 32 feet and a length of 450 feet, this dam has a storage capacity of 130 acre-feet and a maximum discharge rate of 1700 cubic feet per second. Situated on Dry Creek, the dam serves as a vital water resource for the surrounding area, with a surface area of 8 acres and a normal storage capacity of 60 acre-feet.
Managed and regulated by the Oklahoma Water Resources Board (OWRB), Oknoname 051055 is classified as a low hazard potential structure with a condition assessment of 'Not Rated'. Despite its low hazard potential, the risk assessment for this dam is rated as 'Very High', indicating a need for vigilant monitoring and maintenance. The last inspection of the dam was conducted in August 2010, with a scheduled inspection frequency of every 5 years to ensure its structural integrity and safety.
In the event of an emergency, the dam is equipped with a controlled spillway and a single valve outlet gate for controlled water release. Although the Emergency Action Plan (EAP) status and risk management measures are not currently specified, the dam's risk assessment level of 'Very High' underscores the importance of proactive measures to mitigate potential risks and ensure the safety of the surrounding community and environment.

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.
