Lucile Wannamaker Dam dam
Lucile Wannamaker Dam
Lucile Wannamaker Dam, located in Calhoun, South Carolina, is a private-owned earth dam built in 1965 primarily for recreational purposes. Standing at a height of 16 feet and stretching 700 feet in length, the dam has a maximum storage capacity of 416 acre-feet and a normal storage of 256 acre-feet. The dam overlooks the scenic Antley Spring Branch and covers a surface area of 40 acres, making it a popular spot for water resource and climate enthusiasts.
Managed by the South Carolina Department of Health and Environmental Control, the dam is regulated and inspected regularly to ensure its safety and functionality. Despite being classified as low hazard potential with fair condition assessment, the dam is under a very high risk rating (1) due to its structural characteristics and location. Emergency action plans are in place, although specific details regarding their preparation and revision dates are not provided, highlighting the importance of ongoing risk management measures.
While Lucile Wannamaker Dam offers a picturesque recreational setting, its risk assessment underscores the need for vigilant monitoring and maintenance. With its controlled spillway and state-regulated status, the dam serves as a vital structure for both leisure and safety within the Savannah District. As water resource and climate enthusiasts explore the area, they can appreciate the balance between enjoyment and risk mitigation that the dam represents in the beautiful surroundings of Calhoun, South Carolina.

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.
Plan around the weather

About Lucile Wannamaker Dam
Where does the data for Lucile Wannamaker 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.
