Summary
Constructed in 1990 by the USDA NRCS, this dam has a height of 30 feet and a length of 230 feet, with a storage capacity of 39 acre-feet. The dam serves multiple purposes, including flood control and water storage, with a low hazard potential and a moderate risk assessment rating.
Managed by the Natural Resources Conservation Service, Johnny Devaughn is not regulated by the state and does not require permitting or inspections. Despite being unregulated, the dam plays a crucial role in managing water resources in the Caddo County area. Its uncontrolled spillway, with a width of 45 feet, helps to mitigate flood risk and control the flow of the Washita River during periods of heavy rainfall.
With a risk assessment rating of moderate, Johnny Devaughn presents a manageable level of risk to the surrounding community. Although not currently rated for its condition, the dam's functionality and importance in water resource management make it a key structure in the Tulsa District. As an earth dam with a primary purpose of "Other," Johnny Devaughn highlights the significance of private infrastructure in supporting water resource sustainability and climate resilience.

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.
