Mctract Lake Dam dam
Mctract Lake Dam
Mctract Lake Dam in Cobb, Georgia, is a privately owned earth dam primarily used for recreation. Built in 1945, the dam stands at a height of 24.3 feet and has a maximum storage capacity of 69 acre-feet. With a surface area of 7.5 acres, the dam is designed with an uncontrolled spillway and outlet gates. Despite being classified with a low hazard potential, the dam's condition has not been rated, and its last inspection dates back to September 1984.
Located in the Mobile District, Mctract Lake Dam is a significant feature in the local landscape, offering opportunities for outdoor activities and water-based recreation. Although the dam's hazard potential is considered low, a moderate risk assessment of 3 indicates the need for ongoing monitoring and potential risk management measures. With its picturesque setting and historical significance, the dam serves as both a recreational area for visitors and a vital component of the local water resource infrastructure.
For water resource and climate enthusiasts, Mctract Lake Dam presents a fascinating case study of a privately owned earth dam with a mix of historical charm and modern risk assessment challenges. As the dam's condition remains unrated and inspections are long overdue, there is a growing need for updated assessments and potential emergency action plans to ensure the safety and integrity of this important water resource feature. With its unique design and recreational significance, Mctract Lake Dam stands as a reminder of the intersection between human-made structures and natural environments, highlighting the importance of sustainable water management practices in the face of changing climate conditions.

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 Mctract Lake Dam
Where does the data for Mctract 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.
