Siegel Flood Control Dam dam
Siegel Flood Control Dam
The Siegel Flood Control Dam, located in Clayton County, Iowa, was completed in 1938 by the USDA NRCS to mitigate flood risks along the TR-Mississippi River. This earth dam stands at 43 feet tall and spans 324 feet in length, providing a storage capacity of 94 acre-feet. It is designated as a high hazard potential structure but is currently in satisfactory condition, as per the last assessment in June 2019.
Managed by the local government and regulated by the Iowa DNR, the dam serves as a critical flood risk reduction measure in the region. With a drainage area of 0.65 square miles, the dam plays a vital role in protecting the surrounding areas from potential flooding events. Despite its age, the Siegel Flood Control Dam continues to be inspected regularly and meets state permitting and enforcement requirements to ensure its operational efficiency.
For water resource and climate enthusiasts, the Siegel Flood Control Dam presents a fascinating example of infrastructure designed to safeguard communities against the impacts of flooding. Its strategic location, efficient design, and ongoing maintenance highlight the importance of sustainable water management practices in addressing the challenges posed by changing climate patterns. As part of a comprehensive flood risk reduction strategy, this dam serves as a vital component in enhancing the resilience of the local ecosystem and ensuring the safety of residents in the area.

About Siegel Flood Control Dam
Where does the data for Siegel Flood Control 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 below 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.

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.
