Airport Lake dam
Airport Lake
Airport Lake in McMinnville, Tennessee, is a private water resource built in 1967 with a primary purpose not specified. This earth dam structure, standing at 20 feet tall with a hydraulic height of 15.5 feet, serves as a crucial component of the Tribparis Branch watershed. With a storage capacity of 114 acre-feet and a surface area of 10 acres, the lake plays a vital role in managing water resources in the region.
Despite being classified as low hazard potential, the dam at Airport Lake has not been rated for its condition. The last inspection in 2016 indicated a moderate risk level, prompting the need for regular maintenance and risk management measures. Emergency action plans and inundation maps have not been prepared or updated, highlighting potential gaps in emergency response preparedness. Nevertheless, the structure continues to play a key role in water regulation and management in the Warren County area.
As water resource and climate enthusiasts continue to monitor and assess the impact of Airport Lake, it is essential to prioritize regular inspections, risk assessments, and emergency preparedness measures. With its strategic location and significant storage capacity, this private water resource remains a critical asset for the community. Ongoing efforts to ensure the safety and sustainability of Airport Lake will be crucial in safeguarding water resources and mitigating potential risks in the future.

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.
Plan around the weather

About Airport Lake
Where does the data for Airport Lake 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.
