Summary

Constructed in 1976, this earth dam stands at a height of 40 feet and spans a length of 450 feet, providing a storage capacity of 480 acre-feet. It is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a low hazard potential rating. The dam is situated on the TR-Hilliby Creek, within the Tulsa District, and is equipped with a controlled spillway and a single valve outlet gate.

Despite its low hazard potential, Oknoname 107014 poses a very high risk due to its surrounding environment. Currently not rated for condition assessment, the dam meets state regulatory standards for inspection, permitting, and enforcement. However, its emergency action plan status is unclear, raising concerns about preparedness in the event of a disaster. With a risk assessment score of 1, there is a need for improved risk management measures and updated emergency protocols to ensure the safety of downstream communities and the environment.

Enthusiasts of water resources and climate in the area of Oknoname 107014 should take note of the dam's significance in providing recreational opportunities while also recognizing the potential risks associated with its operation. With the dam's location in a high-risk area and a lack of recent condition assessment data, there is a call for increased attention to emergency preparedness and risk management. Monitoring and addressing these factors will be crucial in safeguarding the dam's structural integrity and maintaining the safety of the surrounding community and ecosystem.

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.
