Deerfield Lake Dam dam
Deerfield Lake Dam
Deerfield Lake Dam in Hancock, Georgia, stands as a vital piece of infrastructure in the region, serving not only as a water resource but also as a climate management system. This Earth-type dam, with a height of 16 feet and a length of 750 feet, provides a maximum storage capacity of 168 acre-feet, crucial for maintaining water levels in the area. Despite being uncontrolled, the spillway and outlet gates play a key role in managing water flow and mitigating potential hazards.
Although the dam's hazard potential is rated as low, its risk assessment stands at a moderate level, highlighting the importance of regular inspections and maintenance. The last recorded inspection in February 2005 emphasized the need for a five-year inspection frequency to ensure the structural integrity and safety of the dam. With a moderate risk level and a lack of condition assessment, there is a pressing need for further evaluation and potential risk management measures to safeguard this essential water resource in Georgia.
While Deerfield Lake Dam is not currently regulated by the state, its location in Hancock County, Georgia, showcases its significance as a crucial component of the local water infrastructure. As climate change continues to impact water resources worldwide, maintaining and upgrading dams like Deerfield Lake Dam will be essential for effective water management and mitigating potential risks associated with changing climate patterns.

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 Deerfield Lake Dam
Where does the data for Deerfield 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.
