Summary
This 40-foot tall dam has a hydraulic height of 36 feet and a structural height of 40 feet, with a length of 955 feet and a storage capacity of 932 acre-feet. The dam is classified as low hazard potential with a very high risk assessment rating of 1.
Despite being last inspected in 1980, this dam is equipped with a controlled spillway and a single valve outlet gate for water release. The risk management measures and emergency action plans for this dam are currently not rated or prepared, highlighting a potential area for improvement. With its location in Murray County, Oklahoma, this dam serves as a critical infrastructure for flood control and water resource management in the region, showcasing the importance of proper maintenance and monitoring for sustainable climate resilience.
Overall, SCS-Rock Creek Site-03 stands as a vital structure in the flood risk reduction efforts along Big Sandy Creek, serving the community of Dougherty and surrounding areas. With its historical significance dating back to the 1960s, this dam requires updated inspections and emergency response plans to ensure the safety and reliability of its operations in the face of evolving climate challenges. As water resource and climate enthusiasts, it is crucial to advocate for the continued maintenance and enhancement of such critical infrastructure to safeguard against potential environmental risks and ensure sustainable water management practices for the future.

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.
