Summary
Completed in 1960, this dam stands at a height of 30 feet with a length of 1670 feet, providing a storage capacity of 938 acre-feet and a normal storage of 87 acre-feet. With a controlled spillway and a maximum discharge capacity of 3820 cubic feet per second, this low hazard potential structure serves as a vital resource for mitigating flood risks in the region.
Managed by the Oklahoma state regulatory agency OWRB, SCS-Sandy Creek Site-22 has a very high risk assessment rating and a 5-year inspection frequency. The dam features a valve outlet gate and a stone core foundation, ensuring structural integrity and effective water management. While the condition assessment is currently not rated, the dam's emergency action plan and risk management measures are yet to be fully developed, highlighting the importance of continued monitoring and maintenance to uphold its functionality and safety standards for the surrounding community and environment.
As a key component in the flood risk reduction infrastructure of Pontotoc County, SCS-Sandy Creek Site-22 plays a crucial role in safeguarding the area against potential water-related hazards. With its strategic design and operational capabilities, this earth dam stands as a testament to effective water resource management and climate resilience efforts in Oklahoma. By adhering to state regulations and implementing necessary risk management measures, this dam serves as a valuable asset for protecting lives, property, and natural habitats from the impacts of extreme weather events and rising water levels.

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.
