Dredging

Dredging



If your project involves removal of any material from lake or streambed (muck, sand, gravel, silt, organic material, etc.) a permit may be needed.

Dredging, removal, grooming, etc. of lake and streambed

If you are removing a total of less than 2 cubic yards. Of bed material (about one small dump truck full) in any given year you do not need a permit. So maintaining your pier or boat lift, raking your beach, etc. can be done without a permit if you stay under these yearly limits.

Farm Drainage Ditches

Many of the farm drainage ditches that exist in Wisconsin today were once natural streams that were straightened. There are also many ditches, that drain agricultural land that were entirely man-made to improve drainage and for irrigation of crops.

Permits may also be needed to drive motorized equipment on beaches to manage for invasive plants growing on exposed lake bed. Please visit Beach Maintenance for additional information on managing invasive plants, or visit Water Permits to apply for permits to drive motorized equipment on beaches.
