Green Acres dam
Green Acres
Green Acres is a significant dam located in Henry, Tennessee, serving as a vital water resource in the region. Built in 1965, this earth dam stands at a structural height of 23.5 feet, with a hydraulic height of 20.8 feet, creating a reservoir with a storage capacity of 26 acre-feet. The dam is regulated and inspected by the Tennessee Safe Dams Program, ensuring its safety and compliance with state regulations.
Situated on Old Town Creek, Green Acres plays a crucial role in water management and flood control in the area. With a surface area of 2.3 acres and a drainage area of 0.04 square miles, the dam helps mitigate the risk of flooding and provides essential water storage for agricultural and recreational purposes. Despite being rated as having a high hazard potential, the dam's condition assessment is currently not rated, highlighting the need for ongoing monitoring and evaluation.
Managed by the local government, Green Acres is a key infrastructure project that contributes to the sustainability of water resources in the region. With moderate risk assessment and a history of regular inspections, the dam remains a vital asset for the community. As climate change continues to impact water availability and extreme weather events, the role of dams like Green Acres becomes increasingly important in ensuring water security and resilience in the face of a changing climate.

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 Green Acres
Where does the data for Green Acres 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.
