Summary
With a structural height of 31 feet and a hydraulic height of 27 feet, the dam spans 3,771 feet and has a storage capacity of 427 acre-feet. Despite its low hazard potential, the risk assessment for SCS-Quartermaster Creek Site-28 indicates a very high risk level, emphasizing the need for ongoing monitoring and maintenance to ensure its continued effectiveness.
Managed by the Oklahoma Water Resources Board, the dam is regularly inspected and remains in good condition, although it has not been rated for its current state. With a controlled spillway and a single outlet valve, the dam is equipped to handle a maximum discharge of 1,540 cubic feet per second, offering critical flood protection to the surrounding area. While the dam has not undergone any modifications in recent years, its importance in mitigating flood risks and protecting downstream communities underscores the significance of its continued operation and maintenance.
As a key flood risk reduction structure in the Tulsa District, SCS-Quartermaster Creek Site-28 serves a vital role in the region's water resource management efforts. While its risk level remains a concern, the dam's design by the Natural Resources Conservation Service reflects a commitment to sustainable water infrastructure practices. With ongoing regulatory oversight and regular inspections, this earth dam continues to play a crucial role in safeguarding the local community from potential flooding events, highlighting the intersection of water resource management and climate resilience in Oklahoma.

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.
