Summary
The dam's primary purpose is flood risk reduction along the TR-Keel Sandy Creek, with a height of 28 feet and a hydraulic height of 24 feet. The dam has a storage capacity of 410 acre-feet and a normal storage level of 49 acre-feet, serving as a crucial structure for water resource management in the region.
Despite being categorized as a low hazard potential structure, the risk assessment for SCS-Cherokee Sandy Site-03 indicates a very high risk level. The dam features a controlled spillway with a width of 1 foot and an outlet gate valve for water release. The condition assessment is currently labeled as "Not Rated," with the last inspection date recorded in 1980. While the dam has not undergone recent modifications or assessments, it remains a key component of the state's flood risk mitigation strategy, highlighting the importance of regular inspections and maintenance to ensure its continued functionality and safety for nearby communities and the environment.
Managed by the Natural Resources Conservation Service, SCS-Cherokee Sandy Site-03 stands as a critical infrastructure for flood control and water management in the region. With its stone core and soil foundation, the dam plays a vital role in protecting downstream areas from potential inundation. As climate change continues to pose challenges for water resources and extreme weather events become more frequent, the importance of maintaining and monitoring structures like SCS-Cherokee Sandy Site-03 becomes increasingly evident to safeguard communities and ecosystems from the impacts of flooding and water-related disasters.

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.
