Henry Webb Pond Dam Dam
Henry Webb Pond Dam
Henry Webb Pond Dam, located in Anderson, South Carolina, is a privately owned structure designed by the USDA NRCS and regulated by the SC DHEC. Built in 1992, this earth dam stands at a height of 31 feet and spans 170 feet in length, with a maximum storage capacity of 25 acre-feet. The primary purpose of the dam is for recreation, and it serves as a critical water resource for the surrounding area.
Despite its low hazard potential, Henry Webb Pond Dam is currently in poor condition, as determined by a 2017 inspection. The risk assessment for this dam indicates a very high risk level, emphasizing the need for immediate attention and potential mitigation measures. With a risk rating of 1, it is crucial for stakeholders and authorities to prioritize the safety and maintenance of this structure to prevent any potential disasters and ensure the continued functionality of the dam for water supply and recreational purposes.
Given its significance as a water resource and recreational site, Henry Webb Pond Dam plays a vital role in the local community. As enthusiasts of water resources and climate, it is imperative to monitor the condition of this dam, advocate for necessary repairs and improvements, and work towards sustainable management practices to safeguard its integrity and ensure its long-term viability for future generations.

About Henry Webb Pond Dam
Where does the data for Henry Webb Pond 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 below 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.

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.
