Graham Mill Pond Dam dam
Graham Mill Pond Dam
Graham Mill Pond Dam, located in Horry, South Carolina, is a privately owned structure that serves primarily for recreation purposes. Built in 1930, this earth dam stands at a height of 13 feet and spans a length of 2530 feet. With a storage capacity of 119 acre-feet, the dam provides a serene surface area of 18 acres for water enthusiasts to enjoy.
Managed by the South Carolina Department of Health and Environmental Control, Graham Mill Pond Dam is regulated, inspected, and enforced to ensure its safety and functionality. Despite being classified as having a significant hazard potential, the dam's condition assessment remains unrated as of the last inspection in December 2020. While there are no associated structures or spillways, the dam continues to offer a recreational outlet for visitors to appreciate the beauty of the Little Pee Dee River.
As water resource and climate enthusiasts explore the details of Graham Mill Pond Dam, they can appreciate its historical significance and recreational value while recognizing the importance of proper regulation and maintenance to mitigate potential risks. With its idyllic setting and vital role in providing a recreational oasis, this dam stands as a testament to the intersection of human ingenuity and environmental stewardship in managing water resources effectively.

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 Graham Mill Pond Dam
Where does the data for Graham Mill 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 Significant 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.
