Hudson Lake Dam dam
Hudson Lake Dam
Hudson Lake Dam, located in Villa Rica, Georgia, was completed in 1966 and serves primarily for recreational purposes. The earth dam, with a height of 26.3 feet and a hydraulic height of 18.6 feet, holds a maximum storage capacity of 65 acre-feet and a normal storage capacity of 41 acre-feet. The dam is situated on an unnamed river or stream in Douglas County, Georgia, and is under the jurisdiction of the state with regular inspections conducted.
Despite being categorized as having a low hazard potential, Hudson Lake Dam poses a moderate risk according to a risk assessment rating of 3. The dam has not been rated for its current condition, and there are no emergency action plans or inundation maps prepared for the site. The dam's spillway is uncontrolled, and it features uncontrolled outlet gates. The surrounding area has a drainage area of 134 square miles, with a surface area of 5.5 acres, making it an essential water resource in the region.
For water resource and climate enthusiasts, Hudson Lake Dam provides a fascinating case study of a privately owned structure with public access for recreational activities. The dam's design by SCS and its unique features, such as the buttress core type and uncontrolled spillway, offer insights into dam engineering and management practices. As climate change impacts water resources globally, understanding the risk and management measures associated with dams like Hudson Lake Dam becomes increasingly crucial for sustainable water management and ecosystem preservation.

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 Hudson Lake Dam
Where does the data for Hudson 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.
