Summary

Standing at a height of 17 feet and with a length of 3830 feet, this structure has a storage capacity of 620 acre-feet and a maximum discharge rate of 740 cubic feet per second. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its safety and compliance with state regulations.

Despite being classified as having a low hazard potential, Oknoname 075005 is considered to have a very high risk due to its location and structural characteristics. With a controlled spillway and valve outlet gates in place, the dam has a risk management plan in place to mitigate potential threats. Although the condition assessment is currently not rated, the dam is inspected every five years to monitor its integrity and address any maintenance needs. Additionally, the dam is not owned or funded by any federal agency, making it a unique and privately managed structure in the region.

Overall, Oknoname 075005 serves as an important water resource in the area, providing storage for irrigation, flood control, and other purposes. With a designated emergency action plan and a low hazard potential, the dam plays a crucial role in managing water levels and protecting downstream areas from flooding. As a privately owned and state-regulated structure, Oknoname 075005 represents a collaboration between the owner and regulatory agencies to ensure the safety and functionality of the dam for the community.

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.
