Summary
Built in 1968 by the USDA NRCS, this Earth-type dam stands at 18 feet tall and spans 300 feet in length, with a storage capacity of 68 acre-feet. With a low hazard potential and a moderate risk assessment rating of 3, Johnny Adam serves as a crucial water resource for the surrounding area, contributing to the irrigation needs of the community.
Managed by the Natural Resources Conservation Service, Johnny Adam operates as an uncontrolled dam with a spillway width of 25 feet. While it has not been rated for condition assessment, the dam continues to function effectively in its role of providing water for agricultural purposes. Despite not being under state regulation or inspection, Johnny Adam remains a vital infrastructure for water management in the region, showcasing the importance of private ownership in sustaining water resources in rural areas.
With its location in the SE1/4 S16 T5N R12EIM coordinates and its proximity to the USACE Tulsa District, Johnny Adam represents a collaborative effort between private owners and federal agencies to support water conservation efforts. Its historical significance and continued operational success highlight the intersection of water resource management and climate resilience, making it a key site of interest for water enthusiasts and environmental advocates alike.

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.
