Summary

Completed in 1960, this Earth dam stands at a height of 18 feet and has a storage capacity of 82 acre-feet. With a primary purpose classified as "Other," this structure serves various functions within the region. It is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspection, enforcement, and permitting processes to ensure its safety and compliance with state regulations.

The dam, situated on the TR-Little River, plays a crucial role in managing water resources and controlling the flow of water in the area. With a spillway type classified as "Controlled," it has a spillway width of 1 foot and can handle a maximum discharge of 800 cubic feet per second. Despite being rated as having a "Very High" risk level, the condition of the dam is currently assessed as "Not Rated," with no emergency action plan (EAP) in place. While the hazard potential is deemed "Undetermined," the risk management measures and assessment for the dam are yet to be fully documented.

Overall, Oknoname 125016 is a significant infrastructure within the Tulsa District, serving the community of Maud and surrounding areas. As a privately owned dam with a complex design, it plays a crucial role in water management and flood control efforts. With its strategic location and functional capabilities, the dam requires continued monitoring and assessment to ensure the safety of residents and the sustainability of water resources 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.
