Thomas Bros Lake Dam dam
Thomas Bros Lake Dam
Thomas Bros Lake Dam, located in Forest Green, Missouri, was completed in 1942 and stands at a height of 25 feet. This earth dam, primarily used for purposes other than flood control or water supply, has a maximum storage capacity of 187 acre-feet and a normal storage capacity of 117 acre-feet. With a surface area of 14 acres and a drainage area of 220 square miles, the dam poses a high hazard potential.
Despite being privately owned and not regulated by the state, Thomas Bros Lake Dam remains a significant structure in the region, serving as a vital resource for water management and conservation. The dam, built with a buttress core type, plays a crucial role in controlling the flow of the TR-E FK CHARITON RIV river or stream. Its condition remains unrated, and there is no current emergency action plan in place, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality for the surrounding community and environment.
As water resource and climate enthusiasts explore the intricate details of Thomas Bros Lake Dam, its historical significance and impact on the local ecosystem become apparent. The dam's presence not only alters the landscape but also influences the water flow and storage within the region. With its high hazard potential and lack of state regulation, the dam represents a unique case study in the management of private water infrastructure in Missouri. Continued attention to its maintenance and emergency preparedness will be crucial in safeguarding the surrounding area from potential risks and ensuring sustainable water resource management for future generations.

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 Bros Lake Dam
Where does the data for Thomas Bros Lake 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 High 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.
