Twin Lake #2 dam
Twin Lake #2
Twin Lake #2, located in Monroe, Tennessee, is a privately owned earth dam built in 1966 for fire protection, stock, or as a small fish pond. The dam has a hydraulic height of 13.5 feet and a structural height of 22 feet, with a length of 119 feet and a storage capacity of 30 acre-feet. The reservoir covers an area of 4 acres and is fed by the Hot Water Branch river or stream.
Despite being privately owned, the dam falls under the jurisdiction of the state of Tennessee and is not regulated or inspected by state agencies. The last inspection was conducted in January 2018, with a hazard potential rated as significant and a moderate risk assessment score of 3. While the dam is not currently rated for its condition, it is crucial to ensure its safety and maintenance to prevent any potential risks or hazards in the future.
Water resource and climate enthusiasts can appreciate the unique purpose of Twin Lake #2 and its contribution to fire protection and local aquatic life. The dam's uncontrolled spillway type and lack of outlet gates present challenges that need to be addressed for effective risk management. As a significant structure in the area, Twin Lake #2 serves as a reminder of the importance of proper dam maintenance and emergency preparedness in safeguarding water resources and the surrounding environment from potential threats.
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 Twin Lake #2
Where does the data for Twin Lake #2 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.
