Summary
Completed in 1965, this dam stands at a height of 39 feet and spans 855 feet in length, with a storage capacity of 523 acre-feet. The dam is situated on the TR-WEST WINTER CR stream within the Tulsa District and is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being rated as having a low hazard potential, the dam at SCS-Winter Creek Site-01b is deemed to have a very high risk due to its surrounding conditions. The dam features a controlled spillway with a width of 1 foot and is equipped with one valve outlet gate. State inspection, permitting, and enforcement are in place for this structure, although the last inspection date recorded was in 1980. The risk assessment for this dam is categorized as very high, with a DSAC assigned date and a risk management strategy that is yet to be detailed.
Overall, SCS-Winter Creek Site-01b serves as a key infrastructure for flood risk mitigation in the region, highlighting the importance of water resource management and climate resilience efforts in safeguarding communities from natural disasters. This dam's history, design specifications, and risk profile provide valuable insights for water resource and climate enthusiasts interested in understanding the complexities of dam infrastructure and the associated regulatory frameworks in place to ensure public safety.

Dam Data Reference
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.
