Summary
This recreational dam, completed in 1940, stands at a height of 35 feet with a length of 900 feet and a storage capacity of 1800 acre-feet. Managed by the Oklahoma Water Resources Board, Stanley is regulated, permitted, and inspected by state authorities to ensure its safety and compliance with environmental standards.
Despite being classified as having a low hazard potential, Stanley poses a very high risk due to its outdated infrastructure and lack of condition assessment. The dam's emergency action plan is not updated, and there are no measures in place to manage potential risks effectively. The risk assessment highlights the urgent need for improvements to mitigate the dangers associated with Stanley and ensure the safety of the surrounding community.
In the event of an emergency, contact information and inundation maps are not readily available, raising concerns about the dam's emergency preparedness. With its risk level at an all-time high, Stanley requires immediate attention and investment in modernization and safety measures to prevent any potential disasters. As water resource and climate enthusiasts, it is crucial to advocate for the necessary upgrades to protect both the dam and the environment it serves.

Dam Data Reference
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.
