Fairfield Dam B (Main Dam) dam
Fairfield Dam B (Main Dam)
Fairfield Dam B (Main Dam) in Fairfield, South Carolina, is a captivating structure designed by Gibbs & Hill for hydroelectric purposes, with a primary dam type of Earth and core types of Stone. Completed in 1977, this impressive dam stands at a height of 155 feet, with a hydraulic height of 169 feet and a structural height of 204 feet. It boasts a storage capacity of 400,000 acre-feet, providing essential water resources for the region.
Managed by a public utility and regulated by the Federal Energy Regulatory Commission, Fairfield Dam B plays a crucial role in water management and energy generation in the area. With a high hazard potential and risk assessment rating of 2, this dam is regularly inspected to ensure its safety and reliability. Despite facing potential risks, the dam has not had a condition assessment available, highlighting the need for ongoing monitoring and maintenance to safeguard its integrity.
Located on Frees Creek and the Broad River, Fairfield Dam B is a key feature in the landscape, contributing to the surrounding environment and serving as a vital infrastructure for the community. With its significant storage capacity and hydroelectric capabilities, this dam represents a fusion of engineering excellence and environmental stewardship in the face of climate challenges.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Fairfield Dam B (Main Dam)
Where does the data for Fairfield Dam B (Main Dam) come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
