Wilmington Twp 3 dam
Wilmington Twp 3
Wilmington Twp 3, also known as Rosie Stoltz 402, is a private dam located in Houston, Minnesota, along the Winnebago Creek. Constructed in 2011 by G-CUBED, this earth dam stands at a height of 18 feet and serves the primary purpose of flood risk reduction in the area. The dam has a storage capacity of 103 acre-feet and covers a drainage area of 1.3 square miles, providing essential protection to the surrounding region.
Managed by the Minnesota Department of Natural Resources, Wilmington Twp 3 has been deemed to have a low hazard potential with a satisfactory condition assessment as of the last inspection in May 2012. While the dam does not have spillways or locks, it fulfills its role effectively in mitigating flood risks and ensuring the safety of nearby residents. With state-regulated permitting, inspection, and enforcement in place, the dam remains a crucial asset for water resource management in the region.
Overall, Wilmington Twp 3 stands as a vital infrastructure asset in the flood-prone area of Camp Winnebago, offering protection, peace of mind, and effective flood risk reduction measures for the local community. Its strategic location, design, and regulatory oversight make it a noteworthy structure for water resource and climate enthusiasts interested in sustainable water management practices in Minnesota.
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 Wilmington Twp 3
Where does the data for Wilmington Twp 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.
