Summary

Built in 1960, this earth dam stands at 18 feet high and stretches 715 feet in length, with a maximum storage capacity of 65 acre-feet. It serves as a crucial structure for controlling the flow of the TR-DAVE BLUE CREEK, with a spillway width of 1 foot and a maximum discharge capacity of 3100 cubic feet per second.

Despite being classified as having a low hazard potential, Oknoname 027008 presents a very high risk due to its location and the potential consequences of a failure. The dam is under state regulation and inspection by the Oklahoma Water Resources Board, ensuring that it meets the necessary safety standards. However, the condition assessment of the dam has not been rated, highlighting the need for further evaluation and potential risk management measures to be implemented.

With its strategic location and important role in water management, Oknoname 027008 serves as a critical infrastructure for the region. As water resource and climate enthusiasts, it is important to monitor and assess the condition of such dams to ensure the safety and security of the surrounding communities and ecosystems. The data provided offers a glimpse into the intricacies of this dam and underscores the importance of continued vigilance in maintaining its structural integrity and safety standards for the future.

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.
