Summary
Completed in 1975, this dam stands at a height of 27 feet with a length of 1100 feet, providing a maximum storage capacity of 197 acre-feet and a normal storage of 19 acre-feet. The dam features a controlled spillway and a single valve outlet gate, with a significant hazard potential and fair condition assessment as of August 2011.
Managed by the Oklahoma Water Resources Board, SCS-Quapaw Creek Site-07 is subject to state permitting, inspection, and enforcement. The dam's risk assessment is classified as very high (1), highlighting the importance of ongoing monitoring and maintenance to ensure the safety and effectiveness of the structure. The surrounding area is at risk of inundation in the event of a breach, making the implementation of risk management measures crucial for the protection of downstream communities and ecosystems.
As part of the flood control infrastructure in the Tulsa District, SCS-Quapaw Creek Site-07 plays a vital role in mitigating flood risks and protecting the local environment. With its strategic location and design features, this dam serves as a key asset in safeguarding against potential disasters and promoting sustainable water resource management in the region. Climate enthusiasts and water resource professionals alike can appreciate the intricate balance of engineering and natural systems at play in this essential piece of infrastructure.

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.
