Mcquillan & Yamnitz Lake Dam dam
Mcquillan & Yamnitz Lake Dam
Mcquillan & Yamnitz Lake Dam, located in Lizella, Georgia, is a privately owned earth dam primarily used for recreational purposes. Standing at a height of 50 feet, the dam has a storage capacity of 89 acre-feet, with a maximum discharge rate of 77 cubic feet per second. The dam features an uncontrolled spillway and outlet gates, and has not been inspected since September 2010, with its hazard potential and condition assessment marked as undetermined and not rated, respectively.
Despite being in a moderate risk category, with a hazard potential yet to be determined, Mcquillan & Yamnitz Lake Dam remains an important structure for recreational activities in the area. With a surface area of 4 acres and a normal storage capacity of 77 acre-feet, the dam serves as a popular location for outdoor enthusiasts looking to enjoy water-based activities. While its condition assessment is listed as not rated, the dam's risk management measures and emergency action plan status remain undisclosed, suggesting a need for further evaluation and potential updates to ensure the safety of surrounding communities.
As a private dam in the Mobile District, Mcquillan & Yamnitz Lake Dam's risk assessment and hazard potential are essential aspects to monitor and address to maintain the safety of the surrounding area. With its unique design and purpose geared towards recreation, the dam serves as both a functional structure and a potential risk factor, underscoring the importance of regular inspections and risk management measures to protect both the environment and the community.

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 Mcquillan & Yamnitz Lake Dam
Where does the data for Mcquillan & Yamnitz 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 Undetermined 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.
