Waubonsie Cr. Watershed Site 36-2 dam
Waubonsie Cr. Watershed Site 36-2
Located in Mills, Iowa, Waubonsie Cr. Watershed Site 36-2 is a vital water resource managed by the local government with oversight from the Iowa Department of Natural Resources. This site, designed by the USDA NRCS, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. The earth dam, completed in 1983, stands at a height of 53 feet and has a storage capacity of 144 acre-feet, with a drainage area of 0.38 square miles.
With a low hazard potential and a moderate risk assessment rating, Waubonsie Cr. Watershed Site 36-2 plays a crucial role in protecting the surrounding area from flooding and providing essential water resources for various purposes. The dam's spillway type is uncontrolled, and it has not been modified since its completion. Although the condition assessment is currently rated as "Not Rated," the site is regularly inspected and maintained to ensure its functionality and safety for the community.
As part of the Omaha District, this watershed site contributes to the overall water management efforts in the region. With its strategic location and design features, Waubonsie Cr. Watershed Site 36-2 stands as a testament to effective water resource management and serves as a valuable asset for both water enthusiasts and climate advocates seeking to understand and promote sustainable water conservation practices.
Dam data reference
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 Waubonsie Cr. Watershed Site 36-2
Where does the data for Waubonsie Cr. Watershed Site 36-2 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.
