Mashburn Millpond Dam dam
Mashburn Millpond Dam
Mashburn Millpond Dam, also known as Lake Alice Dam, is a private earth dam located in Forsyth, Georgia, along the Little Ridge Creek. Built in 1930, this recreational dam stands at a height of 25.4 feet with a structural height of 15.5 feet. It serves primarily for recreational purposes, offering a serene setting for water resource and climate enthusiasts to enjoy.
With a storage capacity of 108 acre-feet, Mashburn Millpond Dam poses a low hazard potential and has not been rated for its condition assessment. While it is not regulated or inspected by the state, the dam maintains a moderate risk assessment level. Although the dam has an uncontrolled spillway and outlet gates, it has not undergone any significant modifications or inspections in recent years, highlighting the need for continued monitoring and maintenance to ensure its safety and stability for the surrounding community.
Overall, Mashburn Millpond Dam provides a tranquil recreational space along Lake Sidney Lanier, inviting visitors to appreciate the beauty of nature while also raising awareness about the importance of proper dam management and maintenance in the face of changing climate conditions. Water resource and climate enthusiasts can explore this historic structure and learn about the significance of responsible dam ownership and operation in preserving the natural environment.
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 Mashburn Millpond Dam
Where does the data for Mashburn Millpond 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.
