Macedonia Dam dam
Macedonia Dam
Macedonia Dam, located in Union, South Carolina, is a Federal-owned structure managed by the Forest Service. Built in 1992, this Earth-type dam primarily serves as a Fish and Wildlife Pond, with additional purposes for recreation. Standing at a height of 22 feet and with a maximum storage capacity of 99 acre-feet, the dam plays a crucial role in managing water resources in the region.
With a low hazard potential and a moderate risk assessment rating, Macedonia Dam is a key asset for the community. While not currently rated for its condition, the dam has regular inspections by the Forest Service to ensure its safety and functionality. The dam's uncontrolled spillway type and moderate discharge capacity of 419 cubic feet per second further highlight its importance in managing water flow and mitigating potential risks in the area.
For water resource and climate enthusiasts, Macedonia Dam offers a fascinating insight into the intersection of infrastructure, environmental conservation, and recreational opportunities. As a Federal-owned structure, it stands as a testament to the ongoing efforts to balance the needs of wildlife, recreation, and water management in the region. With its strategic location on a tributary of Johns Creek, Macedonia Dam plays a vital role in maintaining the ecological balance and enhancing the quality of life for both humans and wildlife in Union, South Carolina.

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 Macedonia Dam
Where does the data for Macedonia 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.
