Lake Windsor Dam dam
Lake Windsor Dam
Lake Windsor Dam, located in Gwinnett, Georgia, was completed in 1951 and serves as a recreational hub for the local community. This earth dam, with a height of 22 feet and a length of 600 feet, provides a storage capacity of 54 acre-feet and covers a surface area of 6 acres. Although the dam is uncontrolled, its low hazard potential and moderate risk assessment make it a reliable structure for managing water resources in the area.
Owned by the local government, Lake Windsor Dam is not regulated by the state and has not undergone recent inspections or condition assessments. Despite being of unknown design and construction, the dam continues to function effectively, demonstrating its resilience over the years. With its primary purpose being recreation, the dam stands as a testament to the importance of water management and conservation efforts in the region.
As a focal point for outdoor activities and a vital component of the local landscape, Lake Windsor Dam represents a harmonious blend of human engineering and natural beauty. Its historical significance and ongoing use for recreational purposes highlight the importance of maintaining and preserving water resources in a changing climate. Enthusiasts and conservationists alike can appreciate the role of this dam in providing both leisure opportunities and essential water supply functions for the surrounding community.
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 Lake Windsor Dam
Where does the data for Lake Windsor 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.
