Clean Water - Fall Clean-Up 

Fall is the best time to fertilize lawns and control weeds. Here are some tips for keeping a healthy fall lawn that looks nice and protects the health of nearby lakes and streams:

Mow – Mow often, leave clippings on the lawn and leave your grass 2.5 to 3 inches high. This strengthens roots and retains moisture for a green, resilient lawn.

Control Weeds – Fall is the best time to treat dandelions, plantain, clover and creeping Charlie. Limited numbers of weeds should be removed by hand or spot-treated with herbicide.

Sweep up - Sweep up and reuse lawn care products that fall on streets, sidewalks and driveways

Rake – Rake leaves to keep them out of storm drains and nearby water bodies, where they release phosphorus and other unwanted nutrients. Keep them away from driveways, streets and sidewalks.

What to do with leaves – There are a few ways you can get rid of leaves:

  • Compost – Recycles nutrients

  • Mulch – Use leaves as mulch, either whole or shredded

  • Mow – If there is less than 2 inches of leaves on your lawn, leave them in place and make several passes over them with a power mower. This provides your lawn valuable nutrients and makes it look like you just raked!

Taking out docks or equipment this fall? Prevent the spread of AIS!

The crisp weather signals the approach of winter, and with it, thousands of Minnesotans will be storing their boats, docks, lifts, and other water-related equipment until spring. Unfortunately, the movement of docks and equipment is a common way for aquatic invasive species (AIS) to spread. Here are some tips to make sure it doesn’t happen to you!

Inspect: Carefully inspect everything to make sure there are no aquatic invasive species (AIS) such as zebra mussels, Eurasian watermilfoil, or New Zealand mudsnails attached.Look on the posts, wheels, and underwater support bars of docks and lifts, as well as any parts of boats, pontoons, and rafts that may have been submerged in water for an extended period. In newly infested waters, adult zebra mussels may not be abundant and you might notice only a few mussels on your equipment.

Use permitted service providers: Minnesota law requires lake service providers –- anyone hired to install or remove water-related equipment including structures from bodies of water -– to undergo training on preventing the spread of AIS. The providers will have a yellow sticker displayed on their vehicle (shown here) and their permit within. The DNR provides a list of permitted providers.

Obtain a permit for transporting watercraft and equipment: Because it is illegal to transport any watercraft carrying AIS away from a body of water, even to storage, boaters in this situation must obtain a one-way permit from the Minnesota Department of Natural Resources. The permit allows boaters to legally bring their boat to a decontamination station and then to storage. For more information, visit
