Summary
Completed in 1965, this earth dam stands at a height of 33 feet and has a storage capacity of 1056 acre-feet. With a significant hazard potential and a very high risk assessment rating, this dam plays a critical role in protecting the surrounding area from potential flooding events.
Managed by the Oklahoma Water Resources Board, SCS-Delaware Creek Site-010 is equipped with a controlled spillway and a single valve outlet gate. Despite being last inspected in 1980 and not currently rated for condition assessment, the dam is regularly monitored and has state permitting, inspection, and enforcement in place. With a maximum discharge capacity of 3235 cubic feet per second, this dam serves as a crucial infrastructure for water resource management and climate resilience in the region.
The site also features the involvement of the Natural Resources Conservation Service in its design, adding to its environmental significance. With its strategic location and purposeful design, SCS-Delaware Creek Site-010 stands as a testament to the collaborative efforts between state and federal agencies in safeguarding communities and ecosystems against the impacts of extreme weather events and water resource management challenges.

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.
