Summary
Built in 1940, this structure has a dam height of 32 feet and a maximum storage capacity of 211 acre-feet. It is regulated by the Oklahoma Water Resources Board and has undergone inspection and enforcement measures by the state. The dam is situated on the TR-YASHAU CR river/stream and is under the jurisdiction of the state of Oklahoma.
The dam features a controlled spillway and a single valve outlet gate. With a low hazard potential and a very high risk assessment rating, Oknoname 089006 is considered to be in sound condition, though it has not been formally rated. The dam has a history of regular inspections with a frequency of every 5 years, with the last inspection taking place in December 2010. Despite its age, the structure has not undergone any modifications in recent years and does not have an Emergency Action Plan in place.
Overall, Oknoname 089006 serves as an important water resource management tool in the region, providing flood control and storage capabilities. Its presence on the TR-YASHAU CR contributes to the overall water management efforts in the area. As a privately owned dam with state regulation and oversight, it plays a crucial role in ensuring the safety and sustainability of the surrounding ecosystem and communities that rely on its services.

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.
