Summary
Standing at a height of 28 feet, this dam on TR North Mud Creek has a normal storage capacity of 46 acre-feet and a maximum storage of 92 acre-feet. Despite its low hazard potential, the risk assessment for this structure is very high, warranting close monitoring and potential risk management measures.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 137058 is subject to state regulation, permitting, inspection, and enforcement. The dam features a controlled spillway and one valve outlet gate. While the condition assessment is currently not rated, the last inspection in 2011 deemed the structure in satisfactory condition. With a drainage area of 1 square mile and a maximum discharge of 1456 cubic feet per second, this dam plays a crucial role in water resource management in the region.
Although lacking a designated emergency action plan (EAP), the risk associated with Oknoname 137058 is deemed very high, necessitating a proactive approach to risk management. With a history of state oversight and compliance, this earth dam serves as a vital component of the local water infrastructure. As climate change continues to impact water resources, the maintenance and monitoring of structures like Oknoname 137058 are essential for ensuring public safety and resource sustainability 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.
