Muzzall dam
Muzzall
Muzzall, located in Ruthville, Tennessee, is a privately owned Earth dam that was completed in 1947. It stands at a hydraulic height of 21.3 feet and a structural height of 22.8 feet, with a length of 495 feet. The dam has a normal storage capacity of 52 acre-feet and a maximum storage of 62 acre-feet, serving the purpose of water resource management for the surrounding area.
The dam, situated on Tribtrouble Creek, has a low hazard potential and is classified as having a moderate risk level. Despite not being state regulated or permitted, it is inspected every five years for safety and structural integrity, with the last inspection conducted in June 2016. Muzzall's spillway type is uncontrolled, and it does not have any outlet gates. With a drainage area of 0.08 square miles, the dam covers a surface area of 6.1 acres, providing essential water storage for the region.
For water resource and climate enthusiasts, Muzzall represents a piece of Tennessee's infrastructure that plays a crucial role in managing water flow and storage. The dam's historical significance, combined with its current operational status and risk assessment, underscores the importance of maintaining and monitoring such structures to ensure the safety and sustainability of water resources in the area. As a privately owned facility, Muzzall serves as a reminder of the diverse landscape of dam ownership and management practices across the state.

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 Muzzall
Where does the data for Muzzall 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.
