Thomas Lakes (Lower) Dam dam
Thomas Lakes (Lower) Dam
Thomas Lakes (Lower) Dam, located in Owen County, Kentucky, was completed in 1940 and serves as a vital water supply source for the local community. This earth dam stands at a height of 30 feet and has a storage capacity of 115 acre-feet, with a normal storage level of 90 acre-feet. The dam spans 250 feet in length and impounds water from the North Severn Creek, creating a surface area of 6 acres.
Despite its importance for water supply, the dam's condition assessment is rated as poor, with a low hazard potential. The last inspection in October 2016 revealed the need for maintenance and improvements to ensure the structure's safety and stability. While the dam is state-regulated and regularly inspected, there are no associated structures or outlet gates, raising concerns about its operational efficiency and emergency preparedness.
Given its moderate risk level and the need for condition assessment updates, stakeholders and local authorities must prioritize the maintenance and rehabilitation of Thomas Lakes (Lower) Dam to mitigate potential risks and ensure the continued reliability of this crucial water resource infrastructure. With proper management measures and investment in necessary upgrades, the dam can continue to fulfill its primary purpose of water supply for the surrounding area while enhancing resilience to climate variability and ensuring public safety.

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 Thomas Lakes (Lower) Dam
Where does the data for Thomas Lakes (Lower) Dam 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.
