Summary
The dam stands at a height of 39 feet with a hydraulic height of 36 feet and a length of 700 feet, providing a storage capacity of 364 acre-feet. Despite its low hazard potential, the dam's risk assessment is marked as very high (1), signaling the need for careful monitoring and management.
The dam features a controlled spillway and a single valve outlet gate for water release, enhancing its flood control capabilities. While the dam's condition assessment is currently not rated, its last inspection dates back to 1980, indicating the need for updated assessments and maintenance to ensure its continued effectiveness in flood risk reduction. With its location in the Tulsa District and under the jurisdiction of the OWRB, SCS-Winter Creek Site-23 serves as a critical infrastructure for water resource management in the region.
For water resource and climate enthusiasts, SCS-Winter Creek Site-23 offers a fascinating case study in dam engineering and flood risk mitigation. Its history, design features, and risk assessment provide valuable insights into the challenges and considerations involved in managing water resources in a changing climate. Continued monitoring and maintenance of this essential infrastructure will be essential to ensure its resilience and effectiveness in the face of future climate uncertainties.

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.
