Summary
Built in 1962 by the USDA NRCS, this Earth-type dam stands at a height of 62 feet and has a maximum storage capacity of 716 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is equipped with a controlled spillway and a single valve outlet gate.
With a low hazard potential and a very high risk assessment rating, Johnny Cake plays a crucial role in managing water resources in the area. The dam is regularly inspected every 5 years to ensure its structural integrity and safety. Although the condition assessment is currently not rated, the dam is maintained in compliance with state regulations and permitting requirements.
Located on Turkey Creek in Lequire, Oklahoma, Johnny Cake serves various purposes beyond flood control, making it a vital resource for the region. As a key water infrastructure managed by a private entity, the dam contributes to water supply management, irrigation, and environmental conservation efforts in the area. With its historical significance and ongoing importance in water resource management, Johnny Cake remains a valuable asset for water and climate enthusiasts.

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.
