Summary
Completed in 1978, this Earth-type dam stands at a height of 25 feet and has a maximum storage capacity of 66 acre-feet. With a controlled spillway and a low hazard potential, this structure serves a primary purpose of 'Other' and is classified as a low-risk dam with a very high risk assessment rating of 1.
Managed by the Fort Worth District of the US Army Corps of Engineers, Oknoname 137006 has a single valve outlet gate for water release. Despite being last inspected in 2011, with an inspection frequency of 5 years, the dam's condition assessment is currently listed as 'Not Rated'. While the Emergency Action Plan (EAP) status and risk management measures are not specified, the dam is not USACE-owned and is not associated with any federal funding or agencies.
Water resource and climate enthusiasts will find Oknoname 137006 an intriguing structure, given its unique design features and the complex regulatory framework it operates under. With its location in a scenic area of Oklahoma and a rich history dating back to the late 1970s, this dam represents a key component of the local water infrastructure. Further research and monitoring of this dam could provide valuable insights into its impact on the surrounding ecosystem and water management practices.

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.
