Minnesota Public Drainage Manual

The Minnesota Public Drainage Manual (MPDM) was first written and published in 1991 by the Minnesota Department of Natural Resources (MDNR), in collaboration with an advisory committee and lead writers. The MPDM was updated in 2016 via contract by BWSR, in coordination with a large stakeholder project advisory committee. The MPDM is a detailed reference document about Minnesota Statutes, Chapter 103E Drainage for drainage authorities, their advisors (attorneys, engineers, county auditors, watershed district secretaries, viewers, drainage inspectors), and others involved with state drainage law. It is important to recognize that the MPDM provides guidance, but is not rule or law.

The MPDM includes detailed explanation and guidance about the numerous sections and subdivisions of Chapter 103E, including process, procedures and pertinent case law references. The MPDM also includes a Public Drainage System Best Management Practices chapter, as well as templates and forms by local government units that are involved in the administration of Chapter 103E drainage systems.

Chapter 1: Introduction and Definitions

Chapter 2: Administrative and Legal Issues

Note that some interim updates have been made to Section 2.III to recognize changes in statute; these changes are highlighted. All updates to the MPDM will be reviewed by the Drainage Work Group before they are finalized.
