Summary
Completed in 1961, this dam stands at a height of 49 feet and has a hydraulic height of 45 feet. With a storage capacity of 600 acre-feet and a normal storage of 176 acre-feet, it serves as a crucial infrastructure for managing water resources in the area.
Owned and regulated by the Oklahoma Water Resources Board, SCS-Quartermaster Creek Site-18a is equipped with a controlled spillway and a single valve outlet gate. Despite being deemed to have a low hazard potential, it is categorized as having a very high risk assessment due to its location and design. The dam has not been inspected since January 1980, with an inspection frequency of 5 years, highlighting the need for continued monitoring and maintenance to ensure its structural integrity and safety in the face of changing climate patterns.
Located in the Tulsa District and overseen by the Natural Resources Conservation Service, SCS-Quartermaster Creek Site-18a plays a vital role in water resource management and flood control in the region. As climate enthusiasts and water resource advocates, it is essential to keep a close eye on the condition and maintenance of this dam to safeguard the community and environment from potential risks and ensure sustainable water management practices for the future.

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.
