Shamrock Lake Dam dam
Shamrock Lake Dam
Shamrock Lake Dam, located in Stockbridge, Georgia, was completed in 1950 for recreational purposes. This earth dam stands at a height of 35.2 feet and has a hydraulic height of 29.8 feet, with a length of 950 feet and a storage capacity of 1053 acre-feet. With a surface area of 62 acres and a drainage area of 1335 acres, the dam's primary purpose is to provide recreational opportunities for local residents and visitors.
While the dam has a low hazard potential and is currently not rated for its condition assessment, it undergoes inspections every 5 years to ensure its safety and integrity. Managed by the Natural Resources Conservation Service, Shamrock Lake Dam features an uncontrolled spillway and outlet gates, with a moderate risk assessment rating of 3. Despite not being state regulated, the dam is under the jurisdiction of Georgia and is inspected regularly to mitigate any potential risks associated with its operation.
For water resource and climate enthusiasts, Shamrock Lake Dam serves as a vital structure in the local community, offering recreational activities while also playing a role in water management and conservation efforts. As a part of the Mobile District in Georgia, this earth dam provides a serene and picturesque setting for outdoor enthusiasts to enjoy, all while maintaining a key role in the region's water resource infrastructure.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Shamrock Lake Dam
Where does the data for Shamrock 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.
