Summary

Completed in 1970, this Earth-type dam stands at a height of 19 feet and has a storage capacity of 50 acre-feet. The dam serves various purposes and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.

With a low hazard potential and a very high risk assessment rating of 1, Oknoname 137029 has a controlled spillway and is equipped with one valve outlet gate. The dam is situated on TR-HORSETOOTH CR, with a drainage area and maximum discharge rate of 483 cubic feet per second. Despite not being rated for condition assessment, the dam's emergency action plan status and risk management measures are not specified, highlighting the importance of continued monitoring and maintenance for water resource and climate enthusiasts in the region.

Overall, Oknoname 137029 presents an intriguing case study for water resource and climate enthusiasts, showcasing the importance of dam infrastructure in managing water resources in Oklahoma. With its unique characteristics and regulatory oversight, this privately owned dam serves as a critical piece of infrastructure within the state, requiring ongoing attention and management to ensure its long-term safety and effectiveness in mitigating flood risks and supporting water supply needs in the area.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
