Miller dam
Miller
Miller is a privately owned earth dam located in Barnesville, Tennessee, along the Camp Branch river. Built in 1973, this dam stands at a structural height of 25.7 feet and a hydraulic height of 20.1 feet, with a length of 527 feet. With a storage capacity of 72 acre-feet, Miller serves as a significant water resource for the surrounding area, covering a surface area of 5 acres and draining an area of 0.4 square miles.
Despite being privately owned, Miller poses a significant hazard potential, with a moderate risk assessment rating. The dam is not currently rated for its condition, and its last inspection was conducted in April 2020. While the dam has no outlet gates, it does have an uncontrolled spillway type. Its emergency action plan status, inundation maps, and risk management measures are not readily available, hinting at potential gaps in emergency preparedness and response.
Located within the Nashville District of the US Army Corps of Engineers, Miller is a key infrastructure in Lawrence County, Tennessee. The dam is not regulated by the state and does not have a state permit, inspection, or enforcement mechanisms in place. With its historical significance and importance for water storage, Miller is an essential structure for water resource and climate enthusiasts to monitor and assess for its potential impact on the local ecosystem.

About Miller
Where does the data for Miller 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 below 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.

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.
