Haynie Lake Dam dam
Haynie Lake Dam
Haynie Lake Dam in Habersham, Georgia, is a private Earth dam primarily used for recreation, with a maximum storage capacity of 112 acre-feet. The dam, standing at 37 feet tall with a hydraulic height of 12 feet, serves as a popular spot for water enthusiasts and nature lovers alike. Located in the scenic surroundings of Georgia, the dam offers a serene escape for visitors looking to enjoy outdoor activities such as fishing, boating, and picnicking.
Despite its low hazard potential and moderate risk assessment, Haynie Lake Dam has not been rated for its condition as of the last inspection in August 2017. The dam boasts an uncontrolled spillway and outlet gates, with an inspection frequency of every 5 years. While the dam has not been modified in recent years, it continues to provide a safe and enjoyable environment for visitors to appreciate the beauty of its natural surroundings. With its location in the Mobile District and the oversight of the US Army Corps of Engineers, Haynie Lake Dam remains a well-maintained and cherished water resource for the community.
For water resource and climate enthusiasts seeking a tranquil retreat in Georgia, Haynie Lake Dam offers a picturesque setting to appreciate the importance of sustainable water management and conservation efforts. With its recreational purpose and scenic beauty, the dam serves as a reminder of the delicate balance between human activity and the environment. As visitors explore the area and engage in various outdoor activities, they are encouraged to respect and protect this valuable resource for future generations to enjoy.

About Haynie Lake Dam
Where does the data for Haynie Lake 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 below 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.

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.
