Gadient Detention dam
Gadient Detention
Gadient Detention, also known as the Wayne Gadient Structure, is a privately owned earth dam located in Goodhue County, Minnesota. Designed by the USDA NRCS and completed in 1996, this dam serves the primary purpose of flood risk reduction along the Hay Creek-OS river system. Standing at a height of 30 feet and a length of 200 feet, Gadient Detention has a storage capacity of 38.4 acre-feet and a maximum discharge rate of 150 cubic feet per second.
Managed by the MNDNR EWR, this low hazard potential structure is in satisfactory condition as of the last inspection in 2015. While it does not have a spillway, the dam features uncontrolled outlet gates and is situated in a high-risk area according to the risk assessment data. Despite its minimal modifications over the years, Gadient Detention remains an essential component of the local water resource management system and plays a crucial role in mitigating flood risks in the region.
With its strategic location in Red Wing, Minnesota, Gadient Detention serves as a testament to effective collaboration between private owners and government agencies in safeguarding communities against potential flood hazards. As climate change continues to impact water resources, structures like Gadient Detention are vital in enhancing resilience and preparedness for extreme weather events. As efforts to monitor and manage water resources intensify, Gadient Detention stands as a resilient example of proactive flood risk reduction measures in action.

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 Gadient Detention
Where does the data for Gadient 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.
