Public Drainage Ditch Systems

Public drainage authorities work with the DNR on a number of issues, including landowner notifications, regulatory jurisdiction between Minn. Statue 103E and 103G, hydrologic modeling, and technical assistance. There are many drainage authorities in Minnesota: County Boards, Joint County Boards, Watershed Districts, and Water Management Organizations.
