Summary

Completed in 1960, this Earth-type dam stands at 25 feet tall and spans 385 feet in length, with a storage capacity of 60 acre-feet. Despite its low hazard potential, the risk assessment for this dam is classified as very high, indicating the need for vigilant monitoring and maintenance.

With a controlled spillway and a single valve outlet gate, Oknoname 037014 is designed to withstand a maximum discharge of 1600 cubic feet per second. The dam serves purposes beyond flood control, highlighting its versatility in water resource management. The dam's structure, predominantly made of stone and soil, is inspected every 5 years to ensure its integrity and safety, with the last inspection conducted in August 2011.

As a crucial infrastructure in the Tulsa District, Oknoname 037014 plays a vital role in water management in Creek County. Its strategic location and design contribute to the overall environmental and climatic resilience of the region, making it an essential asset for water resource and climate enthusiasts to monitor and support in the face of changing environmental conditions.

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.
