Upper Mulberry River 7 dam
Upper Mulberry River 7
Upper Mulberry River 7, located in Gwinnett, Georgia, is a crucial structure managed by the USDA NRCS, designed for flood risk reduction along Duncan Creek. Built in 1980, this earth dam stands at a height of 40 feet and spans 542 feet in length, with a storage capacity of 1236 acre-feet. The dam serves a primary purpose of flood risk reduction and is associated with the Natural Resources Conservation Service, emphasizing its importance in managing water resources in the region.
With a drainage area of 2.81 square miles and a maximum discharge capacity of 2000 cubic feet per second, Upper Mulberry River 7 plays a vital role in mitigating flood hazards and protecting the surrounding community. Despite its high hazard potential, the dam's condition assessment is currently not available, highlighting the need for regular inspections and maintenance to ensure its structural integrity and effectiveness. While the risk assessment for this structure is moderate, efforts towards risk management measures and emergency preparedness are essential to safeguard against potential threats and ensure the safety of the area.
In the face of climate variability and increasing water-related challenges, facilities like Upper Mulberry River 7 are essential for sustainable water resource management. As a key component in flood mitigation strategies, this dam serves as a critical safeguard against potential disasters, emphasizing the importance of proactive measures and investments in infrastructure to protect communities and ecosystems from the impacts of extreme weather events and changing climate patterns.
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 Upper Mulberry River 7
Where does the data for Upper Mulberry River 7 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.
