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.
