Blacks Creek Reservoir dam
Blacks Creek Reservoir
Blacks Creek Reservoir, located in Rabun County, Georgia, is a vital water supply resource managed by the local government. Constructed in 1987, this earth dam stands at 27 feet tall and has a maximum storage capacity of 24 acre-feet. With a primary purpose of water supply, the reservoir serves as a crucial source of water for the surrounding community in Mt. City.
Despite its low hazard potential, the dam at Blacks Creek Reservoir is subject to regular state inspections to ensure its structural integrity and safety. With an uncontrolled spillway and outlet gates, the reservoir is designed to manage water levels efficiently. The risk assessment for Blacks Creek Reservoir indicates a moderate risk level (3), prompting the need for ongoing risk management measures to safeguard the surrounding area from potential flooding or other emergencies.
Overall, Blacks Creek Reservoir plays a key role in water resource management in Georgia, providing essential water supply for the local community. As an earth dam with a controlled spillway, it exemplifies the balance between water storage and safety measures. Regular state inspections and a moderate risk assessment underscore the importance of maintaining and monitoring this crucial water infrastructure for the benefit of all stakeholders involved.
Dam data reference
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 Blacks Creek Reservoir
Where does the data for Blacks Creek Reservoir 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.
