Whitner's Lake Dam dam
Whitner's Lake Dam
Whitner's Lake Dam, also known as Rodgers Lake Dam, is a privately owned structure located in Dahlonega, Georgia, along Tate Creek. Built in 1917 by the Whitner Bros., this earth dam stands at a height of 29 feet and stretches 210 feet in length, with a storage capacity of 240 acre-feet. The primary purpose of the dam is for recreation, offering a surface area of 17 acres for water activities.
Despite its age, Whitner's Lake Dam has been deemed to have a high hazard potential, although its condition assessment as of March 2016 was satisfactory. The dam is state-regulated and undergoes regular inspections, with the last one conducted in March 2016. The dam's spillway type is uncontrolled, and it features uncontrolled outlet gates. While the risk assessment for the dam is moderate, there are no inundation maps prepared, and emergency action plans are not updated.
Water resource and climate enthusiasts interested in Whitner's Lake Dam can appreciate its historical significance, design characteristics, and the recreational opportunities it provides in the Lumpkin County area. The dam's location along Tate Creek adds to its natural appeal, making it a focal point for outdoor activities. However, ongoing maintenance and risk management measures are essential to ensure the safety and sustainability of this aging infrastructure in the face of changing environmental conditions.

About Whitner's Lake Dam
Where does the data for Whitner's 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 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 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.
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.
