Smith dam
Smith
Smith is a state-regulated dam located in Henry, Tennessee, specifically in the city of Meadow Mead. This Earth type dam, completed in 1936, has a hydraulic height of 14.4 feet and a structural height of 20.7 feet, with a total dam length of 450 feet. The dam has a normal storage capacity of 37 acre-feet and a maximum storage capacity of 85 acre-feet, serving the purpose of water resource management for the surrounding area.
Managed by the Tennessee Safe Dams Program, Smith dam has been assessed to have a low hazard potential and is in satisfactory condition as of the last inspection in July 2019. With a moderate risk assessment rating of 3, this dam plays a crucial role in regulating the flow of the Threemile Branch river/stream. Despite not having any associated structures or federal agency involvement, Smith dam continues to be a key component in the water infrastructure of the region.
With its uncontrolled spillway type and proximity to Memphis District, Smith dam remains a notable feature in the local landscape. While there are no emergency action plans prepared or inundation maps available for this dam, its consistent state inspections and enforcement ensure its reliability in mitigating flood risks and maintaining water resources for the community. Smith dam stands as a testament to Tennessee's commitment to water resource management and climate resilience.

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 Smith
Where does the data for Smith 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 Low 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.
