Summary
Built in 1964 by the USDA NRCS, this dam serves as a flood risk reduction structure with a height of 41 feet and a length of 560 feet. The dam has a normal storage capacity of 28 acre-feet and a maximum discharge rate of 2634 cubic feet per second.
Despite being classified as having a low hazard potential, SCS-Delaware Creek Site-005 is considered to have a very high risk due to its location and surrounding conditions. The dam is equipped with a controlled spillway and a single valve outlet gate. While the condition assessment is listed as 'Not Rated,' the dam undergoes inspections every 5 years, with the last inspection conducted in December 2005. The risk management measures and emergency action plan status for the dam are not specified in the available data.
Overall, SCS-Delaware Creek Site-005 plays a crucial role in managing flood risks in the Johnston County region of Oklahoma. With its historical significance and ongoing state regulation, this earth dam serves as a vital component of water resource management and climate resilience efforts in the area.

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.
