Summary
Designed by USDA NRCS and completed in 1977, this dam stands at a height of 25 feet and has a storage capacity of 259 acre-feet. With a controlled spillway and a maximum discharge of 1780 cubic feet per second, it plays a crucial role in managing water flow in the TR-ELK CREEK watershed.
Despite its low hazard potential, the risk assessment for SCS-Upper Elk Creek Site-37 indicates a very high risk rating. However, its condition assessment is currently not rated, and the last inspection took place in 1980. With valve outlet gates and no associated structures, this dam is essential for flood control in the area. Located in Sentinel, Oklahoma, it is a key infrastructure managed by the Oklahoma Water Resources Board.
Overall, SCS-Upper Elk Creek Site-37 serves as a vital component in the flood risk reduction efforts in Washita County. With its strategic location and design features, this earth dam plays a crucial role in safeguarding the surrounding communities from potential water-related disasters. As climate change continues to impact water resources, the management and maintenance of structures like SCS-Upper Elk Creek Site-37 become increasingly important for ensuring the resilience of the local ecosystem.

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.
