Thomas Dam dam
Thomas Dam
Thomas Dam, located in Davis, Iowa, is a private earth dam completed in 1996 by the USDA NRCS for fire protection, stock, and small fish pond purposes. With a height of 25 feet and a length of 458 feet, the dam has a storage capacity of 81 acre-feet and covers a surface area of 3.2 acres. Situated on Pee Dee Creek in Lake Wapello, the dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state agencies.
Despite being classified as having a low hazard potential and a moderate risk assessment, Thomas Dam remains in good condition with no reported issues. The dam does not have an emergency action plan in place, but it meets regulatory guidelines and is regularly inspected by state authorities. With no associated structures or federal agency involvement, Thomas Dam serves as a vital water resource for the community while also contributing to the local ecosystem by providing habitat for small fish.
In the realm of climate change and water resource management, Thomas Dam stands as a testament to sustainable infrastructure development. As a private structure with a clear purpose and limited risk, the dam showcases the importance of responsible construction and maintenance practices in ensuring water security for future generations. Climate enthusiasts and water resource advocates can appreciate Thomas Dam as a model for effective dam management and environmental stewardship in the face of changing climate patterns.

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
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Thomas Dam
Where does the data for Thomas 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.
