Permit application forms for proposed projects affecting the course, current, or cross-section of lakes, wetlands, rivers and streams

Agencies representing three levels of government (federal, state, and local) in Minnesota regulate certain activities that affect the course, current and cross-section of lakes, wetlands, rivers and streams.
  • Federal – Army Corps of Engineers: Permit Programs under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act
  • State – Minnesota Department of Natural Resources: Public Waters Work Permit Program
  • Local – local government unit(s): Wetland Conservation Act
Work affecting the course, current, or cross-section of a lake, wetland, river or stream may require a permit from one or all of these agencies. The DNR Public Waters Work Permit Program applies to those lakes, wetlands, rivers, and streams identified on DNR Public Water Inventory maps. The Wetland Conservation Act applies to nearly all wetlands not shown on the DNR Public Water Inventory maps. The Corps of Engineers regulatory authority generally covers all water and wetland areas, including those that are regulated by the DNR or subject to the Wetland Conservation Act.
