Summary
This dam stands at a height of 35 feet with a hydraulic height of 32 feet, and a length of 3556 feet. It has a normal storage capacity of 44 acre-feet and a maximum storage capacity of 184 acre-feet, serving an area of 7 acres.
The dam is classified as having a low hazard potential and has not been rated for its condition assessment. Despite its age, it is still regularly inspected by the Oklahoma Water Resources Board, with the last inspection dating back to 1980. The dam has a controlled spillway with a width of 1 foot and an outlet gate equipped with a single valve. While the risk assessment indicates a very high risk level, no specific risk management measures or emergency action plans have been reported for this site.
For water resource and climate enthusiasts, SCS-Quartermaster Creek Site-31 presents an intriguing case study of a historic dam that continues to play a vital role in managing flood risk in the region. With its unique design features and state-regulated status, this dam serves as a key infrastructure asset in protecting the surrounding community from potential inundation events. Despite the lack of recent condition assessments, ongoing regulatory oversight ensures that the dam remains a reliable component of the local water management system.

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.
