Tarrants Millpond Dam dam
Tarrants Millpond Dam
Tarrants Millpond Dam, located in Aiken, South Carolina, is a private earth dam built in 1910 primarily for recreational purposes. The dam stands at a height of 9 feet and has a length of 350 feet, creating a reservoir with a storage capacity of 95 acre-feet. The dam is situated on the Upper Three Runs River and is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC).
Despite its recreational primary purpose, Tarrants Millpond Dam has a high hazard potential and a poor condition assessment as of the last inspection in August 2017. The dam is in need of maintenance and repairs to ensure its structural integrity and safety. Emergency action plans and risk management measures are not currently in place, raising concerns about the potential risks associated with the dam.
For water resource and climate enthusiasts, Tarrants Millpond Dam serves as a poignant example of the importance of proper dam maintenance and oversight. As climate change continues to impact water resources and infrastructure, the need for robust inspection, maintenance, and emergency preparedness measures for dams like Tarrants Millpond becomes increasingly critical to ensure public safety and environmental protection.

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 Tarrants Millpond Dam
Where does the data for Tarrants Millpond 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.
