Ditch & Drainage System
St. Louis County ditches are regulated by the Drainage Authority, which is composed of the County Board of Commissioners. The Drainage Authority is responsible to maintain or improve the county drainage system as needed. Ditches are regulated by Minnesota Statute 103E.
St. Louis County has 500-plus miles of open ditches, consisting of 17 total drainage systems, 10 County Ditches, 5 Judicial Ditches, and 2 State Ditches.
The St. Louis County Board of Commissioners serves as the Drainage Authority, having jurisdiction over a system or project.
- The Drainage Authority is obligated to repair and maintain all systems, but cannot advocate for or against improvements, abandonments, or additions. These must be initiated by landowners.
