Yonce Millpond Dam dam
Yonce Millpond Dam
Yonce Millpond Dam, located in Aiken, South Carolina, is a privately owned earth dam constructed in 1958 for recreational purposes. Standing at a height of 17 feet and spanning 260 feet in length, this dam creates a storage capacity of 54 acre-feet with a normal storage level of 30 acre-feet. The dam impounds Bulls Branch, providing a serene nine-acre surface area for recreational activities.
Despite its low hazard potential, the dam's condition assessment in 2017 revealed it to be in poor condition. This raises concerns about its structural integrity and the potential risks it may pose to downstream residents and the environment. The dam is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and undergoes regular inspections to ensure compliance with state regulations.
Given its historical significance and recreational value, efforts to maintain and improve the Yonce Millpond Dam are crucial. Addressing the poor condition assessment and implementing risk management measures will be essential to safeguard the dam's functionality and safety for both visitors and the surrounding ecosystem. As water resource and climate enthusiasts, it is vital to stay informed about the status of dams like Yonce Millpond to support sustainable water management practices and protect our natural resources.

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 Yonce Millpond Dam
Where does the data for Yonce 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 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.
