Cobb Lake Dam dam
Cobb Lake Dam
Cobb Lake Dam, located in Davisboro Environs, Georgia, was completed in 1968 and serves as a recreational water resource for the local community. The dam, primarily owned by a private entity, stands at a height of 15 feet and has a length of 580 feet, with a storage capacity of 179 acre-feet. With a surface area of 16 acres and a drainage area of 400 acres, the dam provides a tranquil setting for outdoor activities and wildlife habitat.
Despite being classified as having a low hazard potential, Cobb Lake Dam has a moderate risk assessment due to its condition not being rated. The last inspection of the dam was conducted in November 1997, with a recommended inspection frequency of every 5 years. While the dam currently has uncontrolled outlets and spillways, there are no associated structures or locks. Although the dam is not regulated by the state, it is under the jurisdiction of Georgia and falls within the Charleston District of the US Army Corps of Engineers.
Water resource and climate enthusiasts visiting Cobb Lake Dam can appreciate its scenic beauty and recreational opportunities, while also being mindful of the need for regular inspections and maintenance to ensure the safety and longevity of the structure. The dam's location in the Washington County of Georgia offers a peaceful retreat for outdoor enthusiasts and nature lovers, making it a valuable asset for both the local community and visitors seeking to enjoy the beauty of the area's water resources.

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 Cobb Lake Dam
Where does the data for Cobb 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.
