Public waters and public drainage system laws clarified.

This bill clarifies laws regarding public waters and public drainage systems in Minnesota to streamline repair processes and reduce regulatory burdens. It allows drainage authorities to proceed with repairs without commissioner approval when existing records are available, while requiring a notification process and a 60-day review period for repairs lacking such records. The legislation also expands the list of activities that do not require a public-waters-work permit, specifically adding repairs to lawfully established drainage systems and culvert replacements that do not impact trout streams. Additionally, it mandates that the state consider designated wetlands as part of existing drainage systems if their management interferes with authorized drainage functions.
