Little River Watershed Structure No. 35 dam
Little River Watershed Structure No. 35
Little River Watershed Structure No. 35, also known as Eads Dam, is a state-owned earth dam located in Alpharetta, Georgia. Built in 1964 by the Natural Resources Conservation Service, this structure serves as a flood risk reduction measure with a primary purpose of mitigating potential flooding in the area. With a height of 35.2 feet and a storage capacity of 274 acre-feet, this dam plays a crucial role in managing water flow and protecting the surrounding communities.
Despite its important role in flood control, Little River Watershed Structure No. 35 is currently rated as having a high hazard potential and poor condition assessment. The last inspection in June 2017 revealed areas of concern that need to be addressed to ensure the dam's continued effectiveness and safety. The risk assessment for this structure is moderate, indicating a need for proactive risk management measures to mitigate any potential threats to the dam's integrity.
As water resource and climate enthusiasts, it is crucial to monitor and address the condition of structures like Little River Watershed Structure No. 35 to prevent any potential disasters. With proper maintenance and risk management measures in place, this dam can continue to serve its vital role in protecting the community from flooding and ensuring the sustainable management of water resources in the area.
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 Little River Watershed Structure No. 35
Where does the data for Little River Watershed Structure No. 35 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.
