River Ridge Lake Dam dam
River Ridge Lake Dam
Located in Grady, Georgia, the River Ridge Lake Dam is a private structure with a buttress core type standing at 23 feet high, offering a storage capacity of 280 acre-feet. While not state regulated, the dam is subject to regular inspections, with the last one conducted in December 2016. Despite being classified as low hazard potential, the risk assessment for the dam is moderate, indicating a need for ongoing monitoring and management measures.
Although the primary purpose of River Ridge Lake Dam is unspecified, its design features an uncontrolled spillway and outlet gates. With a condition assessment of "Not Rated," the dam presents moderate risks that require attention. The dam's location within the Savannah District of the USACE highlights its importance in water resource management in the region, necessitating a proactive approach to risk mitigation and emergency preparedness.
Water resource and climate enthusiasts will find the River Ridge Lake Dam an intriguing site for study, given its structural characteristics and risk profile. As an unregulated private dam with moderate risk potential, it serves as a reminder of the importance of monitoring and managing these vital water infrastructure assets. Further research and assessment are needed to ensure the safety and resilience of the dam in the face of changing climate conditions and potential hazards.
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 River Ridge Lake Dam
Where does the data for River Ridge 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.
