Summary
S. Lake 12 Dam, located in Chesterfield, South Carolina, was completed in 1938 by the Department of Interior - Fish and Wildlife Service for the primary purpose of creating a Fish and Wildlife Pond. The dam stands at a height of 14 feet with a length of 300 feet, containing a maximum storage capacity of 154 acre-feet and a normal storage of 49 acre-feet. The dam is classified as an Earth dam with a stone core, designed to control the flow of Ham Creek with a maximum discharge capacity of 1430 cubic feet per second.
Despite being labeled as having a low hazard potential and fair condition assessment, the dam is considered to have a very high risk level due to its classification as a very high risk (1) based on the risk assessment conducted. The last inspection of the dam was carried out in October 2015 with an inspection frequency of every 5 years. The dam features a controlled spillway and other controlled outlet gates, allowing for efficient water control and management. The surrounding area has an inundation map prepared and emergency contacts updated to ensure quick response in case of any unforeseen events.

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.
