Moccasin Lake Dam dam
Moccasin Lake Dam
Moccasin Lake Dam, also known as Barnett Lake Dam, is a local government-owned structure located in Winston, Georgia. The dam serves primarily for recreational purposes and is classified as an Earth dam with a buttress core type. Standing at a height of 24.7 feet and with a NID storage capacity of 131.4 acre-feet, the dam overlooks a surface area of 9.2 acres and has a drainage area of 405 acres.
Despite being unlisted for its foundations, Moccasin Lake Dam has been inspected for safety measures, with its last inspection conducted in May 2018. With a hazard potential rated as low and a moderate risk assessment, the dam poses a moderate risk (level 3) and has not been assigned a DSAC date. The dam's spillway type is uncontrolled, while the outlet gates are also uncontrolled. The dam has not been modified over the years, and its condition assessment is currently marked as "Not Rated."
Water resource and climate enthusiasts interested in Moccasin Lake Dam can appreciate its serene location and the recreational opportunities it offers. With a focus on safety and risk management, the dam stands as a testament to responsible stewardship of water resources in the area. Its moderate risk assessment prompts ongoing monitoring and assessment to ensure the continued safety and functionality of this essential water management structure.

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 Moccasin Lake Dam
Where does the data for Moccasin 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.
