Summary
This Earth dam stands at a height of 29 feet and has a length of 900 feet, providing a storage capacity of 260 acre-feet. The dam features a controlled spillway and a single outlet valve for water release.
Despite being classified as having a low hazard potential, SCS-Quapaw Creek Site-05c has been designated as having a very high risk level, highlighting the importance of ongoing monitoring and maintenance. The dam's condition is currently rated as 'Not Rated', with the last inspection conducted in 1980. The dam is under the jurisdiction of the OWRB and is subject to state permitting, inspection, and enforcement protocols to ensure its continued safety and functionality for flood risk reduction in the area.
With the potential for high-risk scenarios and the critical role SCS-Quapaw Creek Site-05c plays in flood risk reduction, water resource and climate enthusiasts will find this dam site to be a compelling case study in the ongoing management and maintenance of essential infrastructure for disaster mitigation and water resource protection.

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.
