Squaw Lake(Dan Maddox) dam
Squaw Lake(Dan Maddox)
Squaw Lake (Dan Maddox) is a privately owned Earth type dam located in Lewis County, Tennessee. Completed in 1963, this dam stands at a structural height of 44.5 feet with a hydraulic height of 33 feet, impounding the waters of Squaw Branch. The reservoir has a normal storage capacity of 862 acre-feet and a maximum storage capacity of 1500 acre-feet, covering a surface area of 56 acres.
With a drainage area of 2.57 square miles, Squaw Lake serves as a critical water resource in the region. The dam's spillway type is listed as uncontrolled, with a spillway width of 0 feet. Although the hazard potential of the dam is deemed significant and the condition assessment is currently not rated, the risk assessment is moderate (3), highlighting the importance of ongoing monitoring and maintenance efforts.
Despite not being under state jurisdiction, Squaw Lake plays a vital role in the local ecosystem and water supply. The dam does not have any associated locks or outlet gates, and the last inspection was conducted in October 2018. With a focus on risk management and safety measures, Squaw Lake serves as a valuable asset in the management of water resources in the Nashville District.
Dam data reference
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 Squaw Lake(Dan Maddox)
Where does the data for Squaw Lake(Dan Maddox) 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 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.
