The Minnesota Buffer Law was signed into law in 2015. The law requires perennial vegetation be implemented along all public waters and public ditches.
Public Waters require a 50 foot buffer to be implemented by November 1st, 2017.
Public Ditches require a 16.5 foot buffer to be implemented by November 1st, 2018.
The DNR has created the buffer protection map that can viewed here.
The Freeborn SWCD Monitoring Plan can be found here.
