Summary
Completed in 1966, this dam stands at a height of 30 feet and has a hydraulic height of 28 feet. It has a NID storage capacity of 193 acre-feet and a maximum discharge of 540 cubic feet per second.
The dam, with a length of 740 feet and a surface area of 6 acres, is equipped with a controlled spillway and one outlet valve. Despite being rated as having a low hazard potential, the risk assessment for this site is very high (1). The last inspection was conducted in 1980, with an inspection frequency of 5 years. The dam's condition is currently not rated, and no emergency action plan has been prepared.
Water resource and climate enthusiasts will find SCS-Winter Creek Site-16 an intriguing structure for its flood risk reduction purpose and the challenges posed by its high risk assessment. The dam's design and construction by USDA NRCS, its state regulation by OWRB, and its location along the TR-LAFLIN CR stream in Grady County, Oklahoma, make it a significant feature in the region's water management infrastructure. As the site continues to be monitored and assessed for potential hazards, it serves as a reminder of the ongoing need for effective risk management measures in the face of changing climate patterns and increasing water resource demands.

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.
