Mackay Point Plant Dam dam
Mackay Point Plant Dam
Mackay Point Plant Dam, located in Jasper, South Carolina, stands as a testament to human ingenuity in creating a space that serves the primary purpose of a Fish and Wildlife Pond. Constructed in 1996, this Earth dam spans 780 feet in length and reaches a height of 12 feet, with a storage capacity of 190 acre-feet. The dam's low hazard potential and fair condition assessment make it a crucial structure for the conservation and protection of the surrounding ecosystem.
Managed by a private owner and regulated by the South Carolina Department of Health and Environmental Control, Mackay Point Plant Dam plays a vital role in maintaining the delicate balance of the TR-Tulifiny River. With a normal storage capacity of 53 acre-feet and a surface area of 19 acres, this dam serves as a haven for various species of fish and wildlife, contributing to the overall biodiversity of the region. Despite its modest size, the dam's impact on the local environment is significant, providing a sanctuary for aquatic life and enhancing the natural beauty of the area.
As enthusiasts of water resources and climate, the intricate details of Mackay Point Plant Dam's design and function offer a glimpse into the complex interplay between human infrastructure and the environment. With its buttress core type and unlisted/unknown foundations, this dam represents a harmonious blend of engineering expertise and ecological stewardship. The periodic inspections and maintenance efforts ensure that this structure continues to fulfill its purpose, safeguarding the delicate ecosystem of Jasper, South Carolina, for generations to come.

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 Mackay Point Plant Dam
Where does the data for Mackay Point Plant 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.
