Summary
S. Pool G Dam, located in Chesterfield, South Carolina, is a Federal-owned structure primarily designed for fish and wildlife pond purposes. Built in 1965, this Earth dam stands at a height of 14 feet and spans 450 feet in length along the LIGHTWOOD LOG BRANCH river or stream. With a storage capacity of 147 acre-feet and a surface area of 15.8 acres, the dam serves as a vital resource for water management in the region.
Despite its low hazard potential and fair condition assessment, the risk assessment for C. S. Pool G Dam indicates a very high risk level. While it has not been modified in recent years, the dam undergoes inspections every five years, with the last assessment conducted in October 2015. The dam's spillway type is controlled, and it has a maximum discharge capacity of 258 cubic feet per second. The dam is operated by the Department of the Interior Fish and Wildlife Service and is not regulated by the state.
Overall, C. S. Pool G Dam plays a crucial role in maintaining the ecological balance and water resources in the area. As a key structure for fish and wildlife conservation, it represents a significant asset for the community and the environment. With its strategic location and purpose, the dam stands as a testament to sustainable water management practices in South Carolina.

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.
