Misty River dam
Misty River
Misty River, located in Davidson, Tennessee, is a privately owned earth dam constructed in 1996 for fire protection, stock, or as a small fish pond. With a hydraulic height of 22 feet and a structural height of 26 feet, Misty River has a storage capacity of 145 acre-feet and covers a surface area of 14 acres. The dam's spillway type is uncontrolled, with a spillway width of 0 feet, and it is classified as having a low hazard potential.
Despite being privately owned and not regulated by the state, Misty River is subject to regular inspections, with the last one conducted in January 2018 and an inspection frequency of 5 years. The dam's condition is currently rated as "Not Rated," and it has a moderate risk assessment level of 3. While the dam does not have an emergency action plan prepared or meet guidelines, it is considered to have adequate risk management measures in place.
For water resource and climate enthusiasts, Misty River presents an intriguing case study of a privately owned dam with unique purposes and characteristics. Its location in Tennessee and connection to fire protection and stock maintenance make it a notable structure in the region, despite its low hazard potential and moderate risk assessment. The data on Misty River provides valuable insights into the management and oversight of dams, even when they are not subject to state regulation.

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 Misty River
Where does the data for Misty River 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.
