Charles Jeffcoat Dam dam
Charles Jeffcoat Dam
Located in Fairfield, South Carolina, the Charles Jeffcoat Dam, also known as the Roundy/Thames Dam, was completed in 1989 for the primary purpose of recreation. This private earth dam stands at a height of 23 feet and spans 600 feet in length, creating a storage capacity of 198 acre-feet with a normal storage level of 108 acre-feet. Situated on the TR-Morris Creek, the dam is under state regulation by the South Carolina Department of Health and Environmental Control (DHEC).
With a low hazard potential and fair condition assessment as of the last inspection in April 2017, the Charles Jeffcoat Dam provides a safe and enjoyable recreational experience for visitors. The controlled spillway design ensures proper water management, while the surrounding area offers 18 acres of surface area for outdoor activities. Despite being privately owned, the dam is subject to state permitting, inspection, and enforcement, ensuring compliance with regulatory standards to maintain its operational integrity.
For water resource and climate enthusiasts, the Charles Jeffcoat Dam serves as a noteworthy structure within the Savannah District of the US Army Corps of Engineers. Its very high risk assessment rating reflects the critical importance of proper risk management measures to mitigate potential hazards and safeguard the surrounding community. As a key component of the local water infrastructure, the dam plays a vital role in providing recreational opportunities while adhering to state regulations and safety guidelines.

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 Charles Jeffcoat Dam
Where does the data for Charles Jeffcoat 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 Low 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.
