Matthews Lake Dam #2 dam
Matthews Lake Dam #2
Matthews Lake Dam #2, located in McDuffie, Georgia, was completed in 1970 and serves as a recreational site for water and climate enthusiasts. This privately owned Earth dam has a height of 24.3 feet and a length of 440 feet, with a storage capacity of 82.2 acre-feet. The dam's primary purpose is for recreation, offering a serene environment for outdoor activities.
Although the dam's hazard potential is rated as low, it has a moderate risk assessment score of 3. The condition of the dam is currently not rated, with the last inspection conducted in April 1989. Despite being uncontrolled, the spillway type and outlet gates are designed to manage water flow effectively. The surrounding area boasts a surface area of 7 acres, providing ample space for visitors to enjoy nature and engage in water-related activities.
With its picturesque location and recreational offerings, Matthews Lake Dam #2 is a must-visit destination for water resource and climate enthusiasts. As a vital part of the local ecosystem, this dam provides both beauty and functionality, making it a valuable asset to the community. While the dam's risk assessment is moderate, its low hazard potential and effective water management systems ensure the safety of visitors and the surrounding environment.
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 Matthews Lake Dam #2
Where does the data for Matthews Lake Dam #2 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.
