Summary
Completed in 1965, this structure stands at 24 feet tall with a hydraulic height of 19 feet and a length of 650 feet. With a storage capacity of 95 acre-feet, it serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board. Despite its low hazard potential, it is categorized as having a very high risk due to its condition assessment being "Not Rated."
The dam features a controlled spillway and a single valve outlet gate. While it has not undergone recent inspection or assessment, it is subject to regular inspections every five years. Although it is not classified as a US Army Corps of Engineers (USACE) dam, its risk management measures and emergency action plan status are currently not available. With a risk assessment rating of "Very High (1)," Oknoname 137086 presents an intriguing case study for water resource and climate enthusiasts interested in the maintenance and regulation of dams in Oklahoma.

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.
