Mill Creek 3 dam
Mill Creek 3
Mill Creek 3, also known as Ewers, is a local government-owned earth dam located in Boaz, Wisconsin, along Core Hollow Creek. Built in 1961 by USDA NRCS, this flood risk reduction structure stands at a height of 31 feet and has a hydraulic height of 16 feet. With a storage capacity of 135 acre-feet and a drainage area of 2 square miles, this dam plays a crucial role in debris control and flood risk reduction in the area.
Despite its age, Mill Creek 3 is well-maintained, with a fair condition assessment as of September 2020. The dam has a low hazard potential and is inspected every 10 years to ensure its structural integrity and functionality. Managed by the WIDNR, this dam has a moderate risk assessment rating, indicating the importance of continued monitoring and risk management measures to safeguard against potential hazards. The dam's uncontrolled spillway and overall design contribute to its effectiveness in managing water flow and reducing flood risks in the region.
For water resource and climate enthusiasts, Mill Creek 3 serves as a prime example of successful flood risk reduction infrastructure in Wisconsin. Its strategic location, design features, and regulatory oversight by the WIDNR highlight the importance of efficient water management practices in mitigating potential hazards and safeguarding communities against the impacts of extreme weather events. As climate change continues to pose challenges for water resources, structures like Mill Creek 3 play a crucial role in enhancing resilience and protecting vulnerable areas from the adverse effects of floods.
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 Mill Creek 3
Where does the data for Mill Creek 3 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.
