Summary
Completed in 1957, this structure stands at a height of 15 feet and has a maximum storage capacity of 70 acre-feet. The dam's spillway type is reported as "Controlled" with a width of 1 foot, and it is equipped with a single valve outlet gate.
The dam's hazard potential is classified as "Low", however, the risk assessment indicates a very high risk level, with a DSAC assigned date and a risk management measures section left blank. The last inspection was conducted in September 2010, with an inspection frequency of 5 years. The structure is regulated by the OWRB and falls under the jurisdiction of the state of Oklahoma.
Located along the TR-Little Post Oak Creek, Oknoname 031067 presents a unique case study for water resource and climate enthusiasts due to its relatively small size and low hazard potential contrasted with the high risk assessment. Further research and monitoring may be necessary to understand and address the potential risks associated with this dam and to ensure its safety and integrity in the face of changing climate conditions.

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.
