Harcey Stabilizer dam
Harcey Stabilizer
Harcey Stabilizer, located in Winona County, Minnesota, is a privately owned earth dam with a primary purpose of fire protection, stock, or small fish pond. Built in 1962 by USDA NRCS, this dam stands at 32 feet high and 360 feet long, with a storage capacity of 88 acre-feet. Situated on Trout Run Creek, this structure is regulated by the Minnesota Department of Natural Resources and is subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and satisfactory condition assessment, Harcey Stabilizer poses a moderate risk, indicating the need for ongoing risk management measures. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 70 cubic feet per second. While it currently meets guidelines for emergency action planning, there are no inundation maps prepared, and the last inspection was conducted in June 2017, highlighting the importance of regular monitoring and maintenance to ensure the safety and integrity of this critical water resource infrastructure.
As a key component of the St. Paul District's water management system, Harcey Stabilizer serves as a vital tool for fire protection and water storage in the region. With its historical significance dating back to the 1960s, this dam continues to play a crucial role in maintaining water quality, supporting wildlife habitats, and safeguarding communities against potential flood risks. Enthusiasts and climate advocates alike can appreciate the importance of this structure in managing water resources and addressing the challenges of a changing climate in Minnesota.

About Harcey Stabilizer
Where does the data for Harcey Stabilizer 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 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.
