Nottely Dam dam
Nottely Dam
Nottely Dam, also known as Nottely Lake, is a rockfill dam located in Blairsville, Georgia, along the Nottely River. Built in 1942 by the Tennessee Valley Authority (TVA), this Federal-owned structure serves primarily for flood risk reduction, but also supports hydroelectric power generation, recreation, and water supply purposes. Standing at a height of 197 feet, with a hydraulic height of 183 feet and a length of 2300 feet, Nottely Dam has a storage capacity of 216,147 acre-feet and a surface area of 3970 acres.
With a maximum discharge capacity of 189,970 cubic feet per second, Nottely Dam features a controlled spillway with a width of 325 feet and vertical lift outlet gates. The dam is associated with two other structures (GA29101S001 and GA29101S002) and is within the jurisdiction of the Nashville District of the US Army Corps of Engineers. Despite being classified as having a high hazard potential, the condition assessment of Nottely Dam is currently not available, and its risk assessment is deemed very high (1). Emergency action plans are in place, although the details of their preparation and adherence to guidelines are not specified in the data.
Overall, Nottely Dam stands as a critical infrastructure in Union County, Georgia, playing a significant role in managing flood risks, providing essential services, and supporting various recreational activities. Its strategic location and design make it an essential asset in the region's water resource management and climate adaptation efforts, highlighting the importance of ongoing inspections, maintenance, and emergency preparedness to ensure its continued safety and functionality.
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 Nottely Dam
Where does the data for Nottely 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 High 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.
