Agnew dam
Agnew
Agnew, located in Hamilton County, Tennessee, is a privately-owned earth dam constructed in 1961 for fire protection, stock, and recreational purposes. The dam stands at a structural height of 17 feet and a hydraulic height of 14 feet, impounding the waters of Dry Branch to create a small fish pond with a storage capacity of 43 acre-feet. With a surface area of 5 acres and a drainage area of 0.3 square miles, Agnew serves as a vital resource for water storage and recreational activities in the region.
Despite its modest size, Agnew poses a high hazard potential due to its uncontrolled spillway type and lack of outlet gates. The dam has not been rated for its condition assessment, but it undergoes inspections every 5 years to ensure its structural integrity and safety. The risk assessment for Agnew indicates a moderate risk level (3), prompting the need for continued monitoring and potential risk management measures to mitigate any potential hazards associated with the dam.
As an essential component of the local water resource infrastructure, Agnew plays a crucial role in providing water for fire protection and supporting recreational activities in the area. With its high hazard potential and moderate risk level, it is imperative for stakeholders to stay vigilant in monitoring and maintaining the dam to ensure the safety of nearby communities and the sustainability of the water resource for future generations.
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.
Plan around the weather

About Agnew
Where does the data for Agnew 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.
