Roiger Detention dam
Roiger Detention
Roiger Detention, located in Springfield, Minnesota, is a privately owned earth dam designed by the USDA NRCS with a primary purpose of flood risk reduction. Completed in 1986, this structure stands at a height of 32 feet and stretches 750 feet in length, with a storage capacity of 141 acre-feet. Situated on Mound Creek-TR, Roiger Detention serves to mitigate potential flooding events in the area, providing essential protection to the surrounding community in Brown County.
Managed by the Minnesota Department of Natural Resources, Roiger Detention is subject to state regulations, permitting, inspections, and enforcement to ensure its structural integrity and functionality. Despite being classified as low hazard potential with a satisfactory condition assessment, the dam is equipped with uncontrolled spillways and outlet gates. With a moderate risk assessment rating, ongoing risk management measures are essential to maintain the effective operation of this vital flood control structure.
With Congressman Jim Hagedorn representing the area in the US House of Representatives, Roiger Detention plays a crucial role in safeguarding the local environment and population from the impacts of extreme weather events. As a key component of the flood risk reduction infrastructure in the region, this earth dam stands as a testament to the collaborative efforts between private owners, government agencies, and designers to protect water resources and mitigate the effects of climate change in Minnesota.

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 Roiger Detention
Where does the data for Roiger Detention 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.
