Summary
Completed in 1975, this dam stands at a height of 22 feet and has a storage capacity of 181 acre-feet. With a controlled spillway and one valve outlet gate, Meyers Dewayne is regulated and inspected by the Oklahoma Water Resources Board to ensure its safety and functionality. Despite being rated as having a low hazard potential, the dam is classified as having a very high risk due to its location and structural characteristics.
Situated in Harmon County, Oklahoma, Meyers Dewayne serves various purposes beyond flood control, making it an essential water resource for the region. The dam's stone core and soil foundation contribute to its structural integrity, while its maximum discharge capacity of 1264 cubic feet per second ensures efficient water management during periods of high flow. Although the dam's condition assessment is currently not rated, regular inspections every five years help monitor its performance and safety. The presence of emergency action plans and risk management measures further enhance the dam's resilience in the face of potential hazards.
In the realm of water resource management and climate resilience, Meyers Dewayne stands as a notable example of private ownership and state regulation working together to safeguard critical infrastructure. With its strategic location on the TR-Salt Fork Red River and close proximity to Vinson, this earth dam plays a crucial role in water storage and flood prevention for the local community. As climate change continues to pose challenges to water management, the ongoing inspection and maintenance of Meyers Dewayne ensure its readiness to handle evolving environmental conditions and contribute to sustainable water resource practices in Oklahoma.

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.
