Silver Jackets: Minnesota River Flow-Frequency Analysis

The Minnesota River (red) within Minnesota.

Purpose

The Minnesota River Flow-Frequency Analysis project will be assessing the flood risk and resiliency within the Minnesota River Basin. This project will also help Minnesota achieve its hazard mitigation goals through the application of current information and technology to inform potential flow rates of the river and prevent damages from future flood events.

Location

The location of this project is the mainstem of the Minnesota River within Minnesota and includes the regulated reaches.

Description

U.S. Army Corps of Engineers analysis will serve state and federal agencies, such as the Minnesota Department of Transportation (MNDOT), as the primary source of discharge-frequency relationships for several locations along the Minnesota River Basin. Ensuring the discharge-frequency curve is accurate will inform future design decisions made by MNDOT for projects that aim to reduce the impacts of repetitive flooding on MNDOT highways within the basin.

Status

The project is planned to be awarded in the first quarter of fiscal year 2026 and completed in the fall of 2027.

Authority

This project falls under the Floodplain Management Services program authorized by Section 206 of the Flood Control Act of 1960, as amended (33 U.S. Code § 709a).
