Martin's Landing Lake Dam dam
Martin's Landing Lake Dam
Martin's Landing Lake Dam, located in Roswell, Georgia, was completed in 1968 and serves as a recreational water resource on Seven Branch river. Owned privately by Cousin Properties, the dam stands at a height of 34.1 feet and has a length of 800 feet, providing a storage capacity of 885 acre-feet for activities such as boating and fishing. The dam is regulated by the Georgia SAFE DAMS PROGRAM and undergoes regular inspections to ensure its safety and structural integrity.
With a hazard potential rated as high and a satisfactory condition assessment, Martin's Landing Lake Dam poses a moderate risk (3) according to the data. Despite this, the dam meets state regulatory standards with permits, inspections, and enforcement in place. The dam's uncontrolled spillway and outlet gates, combined with the surrounding recreational facilities, make it a focal point for water enthusiasts and climate conservationists alike. The dam's location in Fulton County, Georgia, under the jurisdiction of the Savannah District, further highlights its significance in water resource management and climate resilience in the region.
In the realm of water resource and climate conservation, Martin's Landing Lake Dam stands as a vital structure offering both recreational opportunities and environmental protection. As a privately owned earth dam, its design by Cousin Properties reflects a commitment to balancing human enjoyment with safety and regulatory compliance. With its high hazard potential and moderate risk assessment, the dam underscores the importance of ongoing monitoring and management to ensure its continued role in supporting the surrounding ecosystem and 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 Martin's Landing Lake Dam
Where does the data for Martin's Landing 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 High 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.
