Summary
This flood risk reduction structure stands at a height of 34 feet with a hydraulic height of 31 feet, serving the primary purpose of flood risk reduction along the TR-LAFLIN CR stream. With a storage capacity of 290 acre-feet, the dam has a spillway width of 1 foot and is equipped with a single valve outlet gate.
Despite being in fair condition according to the last inspection in 2011, SCS-Winter Creek Site-14 has a significant hazard potential and a very high risk rating. The dam is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement. While the dam is designed to mitigate flooding in the area, its risk assessment indicates a need for proactive risk management measures to ensure the safety and effectiveness of the structure in the face of changing climate conditions and potential extreme weather events.
For water resource and climate enthusiasts, SCS-Winter Creek Site-14 presents an intriguing case study of a state-regulated earth dam in Oklahoma that plays a crucial role in flood risk reduction for the local community. With its historical significance as a USDA NRCS project completed over five decades ago, the dam serves as a vital water management infrastructure in the region. As climate change continues to impact water resources and weather patterns, the risk assessment and condition of this dam offer valuable insights into the challenges and opportunities for sustainable water resource management in the face of a changing climate.

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.
