Ah Parsons Pond Dam dam
Ah Parsons Pond Dam
Ah Parsons Pond Dam, also known as Rebecca Parsons Dam, is a private structure located in Williamsburg, South Carolina, along the TR-BLACK RIVER. Built in 1954, this earth dam stands at a height of 8 feet and spans 575 feet in length, with a storage capacity of 74 acre-feet. While primarily used for recreation, it is also regulated by the SC DHEC and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite its low hazard potential, the dam's condition has been assessed as poor during its last inspection in 2017. With a maximum storage capacity of 74 acre-feet and a normal storage of 24 acre-feet, the dam poses a potential risk that must be managed effectively. While it currently lacks an Emergency Action Plan (EAP) and other risk management measures, the dam is closely monitored and inspected every five years to mitigate any potential dangers.
Located within the jurisdiction of the state and owned privately, Ah Parsons Pond Dam serves as a recreational resource for the community. With its unique design and historical significance, this dam on the TR-BLACK RIVER is a valuable asset that requires ongoing maintenance and risk assessment to ensure the safety of both the structure and the surrounding area.

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 Ah Parsons Pond Dam
Where does the data for Ah Parsons 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 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.
