Summary
This Earth-type dam stands at a height of 26 feet and was completed in 1960. With a storage capacity of 200 acre-feet, this structure serves a primary purpose classified as "Other," with a spillway type labeled as "Controlled." Despite its low hazard potential, the risk assessment for this dam is rated as "Very High (1)," making it a site of significant importance for water resource and climate enthusiasts.
Managed by the Oklahoma Water Resources Board, Oknoname 051028 is regulated, inspected, and enforced at the state level, ensuring its structural integrity and safety. The dam is situated on the TR-WALNUT CREEK, part of the Tulsa District, with a drainage area yet to be specified. With a normal storage capacity of 50 acre-feet and a maximum discharge of 1600 cubic feet per second, this dam plays a crucial role in water management in the region. Despite its age, the dam has not been officially rated for its condition, highlighting the need for continuous monitoring and assessment to mitigate any potential risks associated with its operation.
In the event of an emergency, Oknoname 051028 currently lacks an Emergency Action Plan (EAP), which is a cause for concern given its high-risk classification. With only one outlet gate in the form of a valve, the dam's emergency preparedness and response mechanisms may need further development to ensure the safety of surrounding communities. As a vital infrastructure in the area, the dam's risk management measures and overall risk assessment need to be regularly reviewed and updated to address any potential vulnerabilities and ensure the continued protection of water resources and climate resilience 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.
