Fort Yargo Lake State Park Dam dam
Fort Yargo Lake State Park Dam
Fort Yargo Lake State Park Dam, also known as Marbury Creek W/S No 24, is a crucial structure in Barrow, Georgia, designed by the Natural Resources Conservation Service to mitigate flood risks along the Marburg Creek. Completed in 1964, this earth dam stands at 49 feet high with a hydraulic height of 43 feet, providing essential flood risk reduction for the surrounding area. With a storage capacity of 7,460 acre-feet and a normal storage capacity of 3,120 acre-feet, this dam plays a vital role in managing water resources and protecting the local community from potential hazards.
The dam's high hazard potential underscores the importance of regular inspections and maintenance to ensure its structural integrity. Despite the satisfactory condition assessment in 2017, the dam's hazard potential and moderate risk assessment (level 3) highlight the need for ongoing risk management measures and emergency preparedness. Managed by the Georgia-SAFE DAMS program, this state-regulated dam serves as a key asset in water resource management, reflecting a commitment to environmental stewardship and climate resilience in the face of changing weather patterns and increasing water-related risks in the region.
As a focal point for water resource and climate enthusiasts, Fort Yargo Lake State Park Dam stands as a testament to the critical role of infrastructure in safeguarding communities and ecosystems. With its uncontrolled spillway and buttress core design, this dam exemplifies the intersection of engineering innovation and environmental protection. By understanding and appreciating the importance of structures like Fort Yargo Lake State Park Dam, enthusiasts can deepen their knowledge of water management strategies, climate adaptation efforts, and the interconnectedness of human activities with natural systems in a rapidly changing world.
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 Fort Yargo Lake State Park Dam
Where does the data for Fort Yargo Lake State Park 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.
