Summary
Completed in 1960, this dam stands at a height of 21 feet and has a storage capacity of 125 acre-feet. With a spillway type of 'Controlled' and a maximum discharge of 1100 cubic feet per second, this structure plays a crucial role in managing water flow in the area.
Managed by the Oklahoma Water Resources Board, Oknoname 119011 has a low hazard potential and a condition assessment that is currently not rated. Despite its age, this dam has not undergone any modifications and is inspected every 5 years. In case of emergencies, the dam is equipped with a valve outlet gate for controlled water release. The risk assessment for this structure deems it to have a very high risk level (1), indicating the importance of proper maintenance and monitoring.
Oknoname 119011 serves as a vital infrastructure for flood protection in Payne County, Oklahoma, under the jurisdiction of the Tulsa District. With its stone core and soil foundation, this earth dam plays a crucial role in managing water levels and preventing potential disasters. As water resource and climate enthusiasts, understanding the details and significance of structures like Oknoname 119011 is essential for appreciating the interconnectedness of water management and environmental sustainability.

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.
