Summary
Built in 1949 by the USDA NRCS, this flood risk reduction structure stands at a height of 44 feet with a hydraulic height of 39 feet and a structural height of 43 feet. The dam has a length of 950 feet and a storage capacity of 982 acre-feet, providing crucial flood protection for the surrounding area along TR-Beaver Dam Creek.
With a high hazard potential and fair condition assessment, SCS-Sargeant Major Creek Site-2 is regularly inspected by the Oklahoma Water Resources Board to ensure its structural integrity and safety. The dam features a controlled spillway and a single valve outlet gate for water release control. In the event of an emergency, the dam lacks an Emergency Action Plan (EAP) and inundation maps, highlighting the need for improved risk management measures to mitigate potential risks associated with the dam's very high risk assessment rating.
This site serves as a vital piece of infrastructure in the region, managed by state authorities for flood risk reduction purposes. Climate and water resource enthusiasts can appreciate the engineering and regulatory aspects of SCS-Sargeant Major Creek Site-2, recognizing the importance of maintaining and enhancing the resilience of such critical infrastructure in the face of climate change and increasing water-related challenges.

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.
