Shamrock Lake Dam dam
Shamrock Lake Dam
Shamrock Lake Dam, also known as Patrick Lake Dam #2, is a private-owned structure located in Carrollton, Georgia. This Earth dam, with a height of 27.3 feet and a length of 660 feet, serves primarily for recreational purposes as it creates a serene lake with a storage capacity of 169 acre-feet. The dam is classified as having a low hazard potential and a moderate risk assessment, making it an important structure to monitor and maintain for the safety of the surrounding community.
Despite its private ownership, Shamrock Lake Dam falls under the jurisdiction of the state of Georgia and is subject to regular inspections. The dam features an uncontrolled spillway and outlet gates, with no associated locks or locks. While its condition assessment is currently undocumented, the dam is considered to meet safety guidelines and poses a moderate risk. Located in a picturesque setting in Carroll County, Shamrock Lake Dam is a vital component of the local landscape and ecosystem, providing both recreational opportunities and potential risks that must be carefully managed by local authorities.
Water resource and climate enthusiasts interested in Shamrock Lake Dam can appreciate its role in creating a tranquil recreational spot while also acknowledging the importance of ongoing maintenance and monitoring to ensure its safety and functionality. As a private-owned structure with state oversight, Shamrock Lake Dam serves as a reminder of the delicate balance between human enjoyment of natural resources and the need for responsible stewardship to prevent potential hazards and protect the surrounding environment.

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 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.
