Warren Twp Road dam
Warren Twp Road
Warren Twp Road, also known as Radatz Group Detention, is a critical infrastructure project located in Rushford, Minnesota, along Rush Creek-TR. This earth-type dam, completed in 1975 by the USDA NRCS, stands at 21 feet in height and spans 470 feet in length. Its primary purpose is flood risk reduction, with a storage capacity of 60 acre-feet and a drainage area of 0.38 square miles. Despite its significant hazard potential, the dam has been assessed as satisfactory and meets regulatory standards set by the MNDNR EWR.
The Warren Twp Road dam plays a crucial role in mitigating flood risks in the area, with a moderate risk assessment rating. Its uncontrolled spillway and outlet gates are designed to handle a maximum discharge of 224 cubic feet per second, safeguarding the surrounding community from potential inundation. Although last inspected in May 2019, the dam's condition remains satisfactory, reflecting the ongoing efforts of the Natural Resources Conservation Service to ensure its structural integrity and operational effectiveness.
For water resource and climate enthusiasts, the Warren Twp Road dam represents a vital piece of infrastructure in Winona County, Minnesota, serving as a key component of the local flood control system. With its buttress core type and earth construction, this dam stands as a testament to the collaborative efforts between local government agencies and federal entities like the USDA NRCS. As climate change continues to impact precipitation patterns and water levels, the importance of maintaining and enhancing such flood risk reduction structures only grows in significance.

About Warren Twp Road
Where does the data for Warren Twp Road 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 Significant 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.
