D C Herlong Pond Dam dam
D C Herlong Pond Dam
D C Herlong Pond Dam, located in Edgefield, South Carolina, is a private earth dam primarily used for irrigation purposes. Built in 1955, the dam stands at 18 feet tall and stretches 545 feet in length, with a storage capacity of 101 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 rated it as poor, indicating a need for maintenance and repair.
The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with regular inspections and enforcement measures in place. The controlled spillway and very high risk assessment suggest the potential for flooding in the surrounding area, making it crucial for the dam to be properly maintained. The risk management measures for D C Herlong Pond Dam are currently unspecified, highlighting the importance of ongoing monitoring and maintenance to ensure the safety and integrity of the structure.
For water resource and climate enthusiasts, D C Herlong Pond Dam presents an intriguing case study in dam management and maintenance. With its historical significance, purpose for irrigation, and potential risks, the dam serves as a reminder of the importance of proper infrastructure upkeep in the face of changing environmental conditions. As discussions surrounding water resource management and climate resilience continue to evolve, the future of D C Herlong Pond Dam will undoubtedly be shaped by ongoing regulatory oversight and risk assessment efforts.

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 D C Herlong Pond Dam
Where does the data for D C Herlong 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.
