Hammontree dam
Hammontree
Hammontree is a privately owned earth dam located in Loudon, Tennessee, near Lenoir City. Built in 1974 on Sinking Creek, this dam stands at a hydraulic height of 26.3 feet and a structural height of 28 feet, with a length of 190 feet. With a storage capacity of 102 acre-feet and a normal storage of 96 acre-feet, Hammontree covers a surface area of 7.3 acres and serves a drainage area of 0.26 square miles.
The dam features an uncontrolled spillway and has been deemed to have a significant hazard potential. Despite not being rated for condition assessment, the dam undergoes inspections every five years, with the last inspection conducted in July 2018. While Hammontree has a moderate risk level, specific risk management measures are not specified in the available data. The dam does not have a designated Emergency Action Plan (EAP) and lacks inundation maps and updated emergency contacts as of the latest data update in March 2021.
Water resource and climate enthusiasts interested in the infrastructure of dams and their environmental impact may find Hammontree's characteristics and risk assessment intriguing. The dam's location on Sinking Creek in Tennessee, its storage capacity, and hazard potential contribute to its significance within the region. Understanding the risk factors associated with dams like Hammontree is crucial for ensuring the safety of surrounding communities and the preservation of water resources in the face of changing climatic conditions.
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 Hammontree
Where does the data for Hammontree 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 Significant 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.
