Summary
Built in 1966 by the USDA NRCS, this dam stands at 32 feet tall and spans 1160 feet in length, with a storage capacity of 324 acre-feet. The dam is situated on the TR-Little Stillwater Creek and is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Stillwater Creek Site-03 indicates a very high risk level, emphasizing the importance of proper management and maintenance. The dam features a controlled spillway and one outlet gate, with a valve for discharge. While the condition of the dam is currently not rated, regular inspections are mandated, with the last one dating back to 1980. With a risk management plan yet to be defined, there is a need for proactive measures to ensure the safety and integrity of this critical infrastructure.
Water resource and climate enthusiasts will find SCS-Stillwater Creek Site-03 to be a significant structure in the region, serving as a vital component in managing flood risks along the Little Stillwater Creek. As a state-owned earth dam, its construction and design by the USDA NRCS reflect a commitment to safeguarding communities from potential water-related disasters. With its location in a high-risk area, there is a call for comprehensive risk assessment and management strategies to uphold the dam's functionality and resilience in the face of changing environmental conditions.

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.
