Summary
This earth-type dam, situated on the TR-North Canadian River, was completed in 1939 and stands at a height of 37 feet. With a storage capacity of 3260 acre-feet and a surface area of 169 acres, Wetumka serves as a crucial resource for the region, providing water for various purposes including irrigation and municipal use.
Operated and regulated by the Oklahoma Water Resources Board, Wetumka's dam boasts a controlled spillway with a width of 4 feet and a single valve outlet gate. Despite being classified as having a low hazard potential, its risk assessment indicates a very high level of risk. While the dam's condition is currently not rated, inspections are conducted every five years to ensure its structural integrity and safety. The local authorities are committed to maintaining the dam's functionality and implementing necessary risk management measures to safeguard the community's water supply.
In the event of an emergency, Wetumka's emergency action plan (EAP) status is currently unreported, highlighting the need for updated protocols and guidelines to respond effectively to any potential threats. With the support of the Tulsa District and state regulatory agencies, efforts are being made to address the high-risk factors associated with the dam and enhance its resilience in the face of climatic challenges. As water resource and climate enthusiasts, staying informed and advocating for sustainable practices is essential in protecting critical infrastructure like Wetumka for future generations.

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.
