Dover Dam dam
Dover Dam
Dover Dam, also known as Lower Tuggle Road Dam, is a local government-owned structure located in Flowery Branch, Georgia. Completed in 1973, this earth dam stands at a height of 28 feet and serves primarily for recreational purposes. Managed by the Natural Resources Conservation Service, Dover Dam has a low hazard potential and is considered to have a moderate risk level.
The dam boasts a storage capacity of 88 acre-feet, with a normal storage level of 32 acre-feet and a surface area of 4 acres. Despite its uncontrolled spillway and outlet gates, Dover Dam has not been inspected since May 1997, with an inspection frequency of 5 years. While its condition assessment is currently marked as "Not Rated," the dam is deemed to meet regulatory guidelines and poses a moderate risk due to its age and lack of recent inspections.
For water resource and climate enthusiasts, Dover Dam presents an interesting case study in dam management and risk assessment. With its unique design and purpose, this structure serves as a vital recreational resource in Gwinnett County, Georgia. As efforts to ensure the safety and longevity of dams across the country continue, Dover Dam stands as a reminder of the importance of regular inspections and risk management measures in maintaining infrastructure integrity and public safety.
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 Dover Dam
Where does the data for Dover 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.
