Summary
Built in 1968 by the USDA NRCS, this earth dam stands at 20 feet high and serves the primary purpose of flood risk reduction along the TR-Sadler Creek. With a maximum storage capacity of 220 acre-feet and a normal storage of 44 acre-feet, this dam plays a crucial role in managing water resources in the area.
The dam's spillway type is controlled with a width of 1 foot, and it has one outlet valve. Despite being rated as having a low hazard potential, the risk assessment for SCS-Upper Elk Creek Site-20 indicates a very high risk level. Although the dam's condition has not been officially assessed, it is still being monitored regularly, with inspections conducted every 5 years. As a vital infrastructure for the region's water resource management, this dam remains a crucial component in safeguarding the surrounding communities from potential flooding events.
Located within the Tulsa District of the USACE, SCS-Upper Elk Creek Site-20 is an essential structure that contributes to the overall flood risk reduction efforts in the area. With its strategic location and design, this dam serves as a key element in the state's regulatory framework for water resource management. As climate change continues to impact water availability and intensity of extreme weather events, the importance of maintaining and upgrading such infrastructure becomes increasingly critical for ensuring the safety and resilience of the local communities.

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.
