Summary
Completed in 1968, this dam has a height of 27 feet and a hydraulic height of 23 feet, with a storage capacity of 353 acre-feet. The dam, situated on the TR-Elk Creek river, serves as a crucial infrastructure for managing water resources in the region.
With a controlled spillway and a low hazard potential, SCS-Upper Elk Creek Site-05 is equipped with a single valve outlet gate for water release. Despite being last inspected in 1980, the dam's condition assessment remains unrated, highlighting the need for updated evaluation and maintenance. The risk assessment for this dam is categorized as very high, underscoring the importance of proactive risk management measures to ensure its safety and performance in the face of climate variability and extreme weather events.
Overall, SCS-Upper Elk Creek Site-05 plays a vital role in mitigating flood risks and safeguarding the local community in Sentinel, Oklahoma. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance of such critical infrastructure to enhance resilience and sustainability in the face of changing environmental conditions.

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.
