Lake Sarrento Dam dam
Lake Sarrento Dam
Lake Sarrento Dam, located in Conyers, Georgia, stands as a private-owned structure designed by FALK in 1964. This Earth-type dam, standing at 13 feet with a hydraulic height of 17 feet, serves primarily for recreational purposes. With a normal storage capacity of 210 acre-feet and a maximum storage of 250 acre-feet, the dam spans 1485 feet in length and covers a surface area of 30 acres.
The dam, situated on PINE MTN. CREEK, is overseen by the state jurisdiction with regular inspections conducted to ensure its structural integrity. Despite being labeled as low hazard potential and not yet rated for its condition, Lake Sarrento Dam presents a moderate risk level with a risk assessment score of 3. While the spillway type is categorized as uncontrolled, the dam operates with uncontrolled outlet gates, and emergency action plans are yet to be prepared or updated.
For water resource and climate enthusiasts, Lake Sarrento Dam offers a fascinating insight into dam engineering and management practices. As a recreational structure in a picturesque setting, the dam serves as a vital component of the local ecosystem and provides opportunities for outdoor leisure activities. With its historical significance dating back to the 1960s, the dam continues to be a focal point for both water conservation efforts and community engagement in Conyers, Georgia.
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.
Plan around the weather

About Lake Sarrento Dam
Where does the data for Lake Sarrento 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.
