Summary

is a privately owned earth dam located in Major County, Oklahoma, specifically in Fairview. Built in 1960, this dam stands at a height of 15 feet with a hydraulic height of 12 feet and a length of 460 feet. The primary purpose of this dam is categorized as "Other," with a low hazard potential and a risk assessment rating of "Very High (1)." Despite being considered low in hazard potential, the risk management measures for Edwards C. are currently unspecified.

Managed by the Oklahoma Water Resources Board (OWRB), this dam is state-regulated, permitted, inspected, and enforced, ensuring its safety and security. The dam's spillway type is controlled, with a spillway width of 1 foot and an outlet gate consisting of a single valve. Although its condition assessment is marked as "Not Rated," Edwards C. remains an essential structure for water resource management in the region, with a normal storage capacity of 30 acre-feet and a total storage capacity of 60 acre-feet.

For water resource and climate enthusiasts, Edwards C. serves as a vital component of the local water infrastructure, contributing to flood control and water supply management in the area. Its location along the TR-Barney Creek and its association with the Tulsa District of the US Army Corps of Engineers emphasize the importance of this earth dam in maintaining water resources and addressing potential risks. As efforts continue to monitor and assess the condition of Edwards C., its role in safeguarding the surrounding communities and natural environment remains a key priority for water resource professionals and stakeholders.

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.
