Summary
Constructed in 1976, this earth dam stands at a height of 21 feet with a hydraulic height of 18 feet. The primary purpose of this structure is classified as 'Other', with a normal storage capacity of 100 acre-feet and a maximum storage of 117 acre-feet. The dam stretches over 607 feet and has a controlled spillway type with a width of 1 foot.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 013015 is regulated, permitted, inspected, and enforced by the state agency. Despite being rated as having a low hazard potential, the risk assessment for this dam is classified as very high, indicating the need for rigorous risk management measures. The last inspection of this structure took place in September 1999, with an inspection frequency of 5 years. While the condition assessment is currently not rated, the dam's emergency action plan (EAP) status and other risk management measures are not specified in the available data.
Overall, Oknoname 013015 serves as a significant water resource infrastructure in Oklahoma, specifically along the TR-BLUE RIVER. With its critical role in water storage and management, it is essential for water resource and climate enthusiasts to monitor the regulatory oversight, risk assessment, and maintenance activities associated with this dam to ensure the safety and sustainability of water resources in the region.

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.
