Scs-Rock Creek Site-14 Reservoir Report
Last Updated: December 18, 2025
SCS-Rock Creek Site-14, located in Murray County, Oklahoma, is a state-regulated earth dam constructed in 1961 by the USDA NRCS with a primary purpose of flood risk reduction along the Rock Creek.

Summary
The dam stands at a height of 45 feet with a hydraulic height of 41 feet, stretching 1850 feet in length and offering a normal storage capacity of 198 acre-feet. With a controlled spillway type and a maximum discharge of 6030 cubic feet per second, this low-hazard potential structure plays a crucial role in mitigating flood risks in the region.
Managed by the Oklahoma Water Resources Board (OWRB), this dam is regularly inspected every 5 years, with the last recorded inspection dating back to January 1980. Despite not being currently rated for its condition assessment, the dam remains a vital asset for the area's flood risk management, especially given the very high risk of inundation associated with its location. With a single valve outlet gate and no associated locks, the SCS-Rock Creek Site-14 serves as a key infrastructure element in the region's water resource and climate resilience efforts.
Although lacking recent risk assessment and emergency action plan updates, SCS-Rock Creek Site-14 continues to fulfill its essential role in flood risk reduction along Rock Creek. With the involvement of state agencies and the USDA NRCS in its design and construction, this earth dam stands as a testament to collaborative efforts in ensuring water resource management and climate adaptation in Murray County, Oklahoma.

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.
