Summary
It has a length of 1300 feet and a storage capacity of 69 acre-feet, making it a crucial water resource in the area. The dam is regulated by the Oklahoma Water Resources Board and is subject to state inspection, permitting, and enforcement.
Despite its age, Oknoname 121004 has a risk assessment of "Very High (1)", indicating the potential for significant hazards. The dam's condition assessment is listed as "Not Rated", suggesting a need for further evaluation. The dam features a controlled spillway with a width of 1 foot and an outlet gate with a single valve. Emergency preparedness measures, such as an Emergency Action Plan (EAP), are not specified for this structure, raising concerns about its safety in the event of a catastrophic event.
Given its critical role in water management and flood control on TR-Jones Creek, stakeholders should prioritize assessing and addressing the potential risks associated with Oknoname 121004. The dam's location near Ash Creek Church and its impact on the surrounding area make it essential to implement robust monitoring, maintenance, and emergency response protocols. Climate change and increasing weather variability underscore the importance of ensuring the resilience of water infrastructure like Oknoname 121004 in the face of evolving environmental challenges.

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.
