If a project involves placing a structure or any other materials on the bed of a public waterway (geothermal energy systems, innovative shoreline cleaning systems, fish habitat structures, etc.), the DNR requires a permit.
Exemptions and permits
If you can’t find a named activity on the list that matches your project, this means the DNR has not created a specific permit for that activity. If this is the case, you can apply for a Miscellaneous Structures Permit.
Please visit Water Permits to apply for permits.
