Summary
is a private dam located in Oil City, Oklahoma, along TR Stage Stand Creek. Built in 1960, this Earth-type dam stands at 17 feet tall and stretches 553 feet in length, providing a maximum storage capacity of 51 acre-feet. With a controlled spillway and a low hazard potential, this dam plays a crucial role in water resource management in the region.
Managed by the Oklahoma Water Resources Board, Edwards L.A. is subject to regular state inspections, permitting, and enforcement to ensure its structural integrity and safety. Despite being classified as "Not Rated" in terms of condition assessment, the dam poses a very high risk, reflecting the importance of continued monitoring and risk management measures. With a single valve outlet gate and a surface area of 4 acres, this dam serves various purposes beyond flood control, highlighting its significance in the local water infrastructure.
In the event of an emergency, the readiness and response protocols at Edwards L.A. remain unclear, as aspects such as emergency action plans and inundation maps have not been prepared or updated. With a risk assessment rating of "Very High (1)," stakeholders and authorities need to prioritize proactive measures to address potential vulnerabilities and safeguard the surrounding communities and ecosystems.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
