Joels Lake Dam dam
Joels Lake Dam
Joels Lake Dam, located in DeKalb, Georgia, was completed in 1956 and serves as a vital recreational resource in the area. With a primary purpose of recreation, this earth dam stands at a height of 27 feet and has a storage capacity of 250 acre-feet. The dam spans 527 feet in length and covers a surface area of 23 acres, providing a serene getaway for water resource and climate enthusiasts alike.
Managed by a private owner, Joels Lake Dam is not regulated by the state but undergoes regular inspections to ensure its safety and functionality. The dam's hazard potential is classified as low, with a moderate risk assessment rating. Despite not being rated for its condition, the dam continues to play a key role in the local community's recreational activities, offering a tranquil escape for visitors to enjoy the beauty of nature.
With its uncontrolled spillway and outlet gates, Joels Lake Dam remains a picturesque landmark in Klondike, Georgia. While it may not boast a high-risk potential, the dam's moderate risk assessment suggests the need for ongoing monitoring and maintenance to ensure its long-term stability. As a beloved recreational spot in the area, this earth dam continues to provide a peaceful retreat for water enthusiasts and nature lovers to appreciate the beauty of Georgia's landscape.
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 Joels Lake Dam
Where does the data for Joels 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 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.
