Summary
Completed in 1962, this earth dam stands at a height of 40 feet with a hydraulic height of 36 feet and a structural height of 40 feet. With a storage capacity of 670 acre-feet and a normal storage of 176 acre-feet, this dam plays a crucial role in managing floodwaters in the area.
The dam features a controlled spillway with a width of 1 foot and an outlet gate in the form of a valve. Despite being assessed as in fair condition as of August 2011, it poses a significant hazard potential and has a very high risk rating. The dam has undergone inspections with a frequency of 3 years, with the last inspection conducted in December 2010. As a key component of flood risk reduction infrastructure in Dewey County, this dam serves as a vital resource for water resource and climate enthusiasts interested in the management of water resources and mitigation of flood risks in the region.
With its stone core and soil foundation, SCS-Quartermaster Creek Site-20 showcases the collaboration between state and federal agencies in ensuring the safety and functionality of critical infrastructure. As part of the flood risk reduction strategy in Oklahoma, this dam stands as a testament to the ongoing efforts to protect communities and ecosystems from the impacts of extreme weather events. For those passionate about water resource management and climate resilience, this site offers valuable insights into the importance of strategic infrastructure investments in safeguarding against the challenges posed by changing climate patterns.

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.
