Mossy Lake Dam dam
Mossy Lake Dam
Mossy Lake Dam, located in Houston County, Georgia, was completed in 1963 and serves as a recreational site for water resource and climate enthusiasts. The earth dam stands at a height of 9 feet and spans 900 feet in length, with a storage capacity of 1260 acre-feet. The dam overlooks Mossy Creek and offers a surface area of 221 acres for outdoor activities such as fishing, boating, and wildlife observation.
While Mossy Lake Dam is primarily used for recreation, it also plays a crucial role in flood control and water management for the surrounding area. With a low hazard potential and a moderate risk assessment rating, the dam is regularly inspected to ensure its structural integrity and safety. The dam's uncontrolled spillway and outlet gates provide a means of releasing excess water during periods of high rainfall, minimizing the risk of flooding and protecting downstream communities.
Managed by private owners, Mossy Lake Dam is not regulated by the state and does not require permitting for operation. The dam's condition assessment is currently listed as "Not Rated," highlighting the need for ongoing monitoring and maintenance to uphold its functionality and safety standards. As a vital component of the local ecosystem and recreational landscape, Mossy Lake Dam remains a significant resource for water enthusiasts and nature lovers alike in the region.

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 Mossy Lake Dam
Where does the data for Mossy 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.
