Summary

This Earth-type dam stands at a height of 25 feet and stretches 245 feet in length, with a storage capacity of 50 acre-feet. Completed in 1960, it serves as a crucial structure for managing water resources in the area, specifically along the TR-ARKANSAS RIVER. Despite its age, the dam is in good condition and poses a low hazard potential according to assessments.

Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 143009 is subject to state regulations, inspections, and enforcement measures to ensure its safe operation. The dam features a controlled spillway and a single valve outlet gate. With a maximum discharge capacity of 700 cubic feet per second, it plays a vital role in flood control and water supply management in the region. The risk assessment for this structure indicates a very high level of risk, highlighting the importance of ongoing monitoring and maintenance efforts to mitigate potential hazards.

In addition to its primary purposes, Oknoname 143009 serves as a testament to the engineering and design standards of its time. Despite being classified as "Not Rated" in terms of condition assessment, the dam continues to play a crucial role in water management activities within the Tulsa District. With its historical significance and functional importance, this structure stands as a reminder of the intricate relationship between water resources and climate resilience in the region.

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.
