Lake Rockdale Dam dam
Lake Rockdale Dam
Lake Rockdale Dam in Georgia is a privately owned structure constructed in 1961 for recreational purposes. The dam, designed by Mr. Mahony, stands at a height of 33 feet and spans a length of 767 feet, holding a storage capacity of 1579 acre-feet. Despite its primary function for recreation, the dam poses a high hazard potential and is rated in poor condition as of the last inspection in March 2019.
Located in Rockdale County, the dam's surrounding area covers 75 acres with a drainage area of 948 square miles. It is regulated by the state's Safe Dams Program, which oversees its inspection, permitting, and enforcement activities. With a moderate risk assessment score of 3, the dam's risk management measures and emergency preparedness status remain unspecified, indicating a need for continued monitoring and maintenance to ensure public safety and environmental conservation.
For water resource and climate enthusiasts, Lake Rockdale Dam presents an intriguing case study of a privately owned earth dam with buttress core types, serving primarily for recreation but also carrying significant safety risks. Its presence in the landscape of Conyers, Georgia, underlines the importance of regular inspections, condition assessments, and risk management practices to safeguard both human life and the surrounding ecosystem from potential hazards associated with dam failure.
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 Lake Rockdale Dam
Where does the data for Lake Rockdale 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 High 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.
