Summary
Completed in 1966, this structure on West Winter Creek stands at 43 feet tall with a hydraulic height of 39 feet, providing a maximum storage capacity of 357 acre-feet. The dam's spillway type is controlled, with a width of 1 foot, and it has a high hazard potential with a fair condition assessment.
Managed by the Natural Resources Conservation Service, SCS-Winter Creek Site-02 has a very high risk assessment rating and is part of the Tulsa District in Oklahoma. Despite being last inspected in 2011, with an inspection frequency of 1, the dam remains in fair condition with a risk management plan in place. With a risk potential that is considered very high, this structure plays a crucial role in mitigating flood risks in the area, showcasing the importance of effective water resource management practices in the face of changing climate conditions.
As water resource and climate enthusiasts, the data for SCS-Winter Creek Site-02 offers valuable insights into the design, construction, and current status of a key flood risk reduction structure in Oklahoma. With its high hazard potential and strategic location on West Winter Creek, this earth dam serves as a critical infrastructure for protecting communities and managing water resources in the region. The information provided highlights the importance of ongoing monitoring, inspection, and risk management measures to ensure the continued safety and effectiveness of such vital water management systems in the face of evolving climate challenges.

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.
