Research Shows AIS Messaging Works

Millions of dollars are spent each year on programs that encourage recreational boaters to help stop the spread of aquatic invasive species like zebra mussels and hydrilla. But do these programs, like the national Stop Aquatic Hitchhikers! and Clean Drain Dry brands, actually work? 

Recently published research from a University of Wisconsin–Madison team shows — for the first time — that yes, they do.

“Before now, we only assumed these messages work,” said Tim Campbell, Wisconsin Sea Grant’s aquatic invasive species outreach specialist and coauthor of the study. “This research shows, for sure, that Stop Aquatic Hitchhikers! and Clean Drain Dry outreach help keep our lakes and rivers free of invasive species.”

Wisconsin DNR Awards $6.1 Million in Surface Water Grants

Big News for Wisconsin's Waters!
The Wisconsin Department of Natural Resources has awarded over $6 million in Surface Water Grants, supporting 426 projects across the state. From rivers and streams to lakes and wetlands, these funds will help protect and restore the waters that define Wisconsin’s lifeblood.

This year’s projects span everything from habitat restoration and water quality improvements to education, outreach, and aquatic invasive species prevention. Standout efforts include restoring over 21 miles of class 1 trout streams through culvert replacements, remeandering creeks and revitalizing wetlands, and improving lake health with shoreline restorations.

A Marathon County initiative will install 35-foot vegetative buffers along waterways, while Lake Ripley (Jefferson County) works to re-establish the native western banded killifish that has been absent for more than 50 years. Meanwhile, hundreds of local partners will continue vital work through the Clean Boats, Clean Waters Watercraft Inspection Program and lake monitoring efforts as part of the Lake Monitoring and Protection Network.

These investments highlight the power of collaboration and a shared commitment to safeguarding Wisconsin’s water legacy for generations to come.

If your local organizations could benefit from a surface water grant, reach out now to determine eligibility and begin developing ideas before the September 2026 pre-application deadline.

Visit the DNR website for more information or to find a Surface Water Grant project in your community.

Wisconsin Lake List Directory

Do you know how many lake districts and associations are in your county? Have you ever wondered how many counties have countywide lake groups? 

Anyone can use the new and improved Wisconsin Lake List Directory on the Extension Lakes website to search Wisconsin’s lake organizations and support community engagement. You can connect to your local organization and learn who is on the board, when the organization was formed, and which lakes are within their jurisdiction. Each lake dropdown includes additional links to more lake data from the Wisconsin Department of Natural Resources.

You can also find lake-related businesses by searching for the services they offer. Businesses included in the Lake List have been added voluntarily; their presence does not imply endorsement.

If you are listed as a contact of an organization, you can request editing access by selecting “Temp Admin Access” in the upper right corner of the organizational record. This feature allows each organization to keep their Lake List record updated.

Do some exploring and see what connections you can make through the Wisconsin Lake List Directory. Reach out to Extension Lakes with any questions.

March 20: Vernal Equinox
That's right - spring is upon us! It may not seem like it with the big snow dump some of us received last weekend, but it's here:

  • Listen for frog calls (Oh, by the way, it's also World Frog Day today!)
  • Look for water birds
  • Taste the maple sap
  • Feel the seasons change

A Sure Sign of Spring: Skunk Cabbage

Photos by Paul Skawinski
A sure sign of spring is the emergence of skunk cabbage (Symplocarpus foetidus) along streams and lakeshores. The first thing to emerge is the large, dark hood that surrounds the flower spike. This dark hood absorbs and concentrates solar heat to volatilize chemicals in the flower, which have a foul smell and attract flies for pollination. The plant can also metabolize starch stored underground, which produces additional heat and can help melt nearby snow.

The giant leaves of skunk cabbage emerge next, rolled up tightly but quickly unfurling and growing to over a foot in diameter. These giant leaves on the landscape indicate areas where groundwater is near to the surface. Many wetland explorers have also noted that the soil around skunk cabbage tends to be very soft and may swallow a boot after a poorly placed step!

Where does the water go?
Spring is a great time to observe runoff on your waterfront property, which can impact water quality and cause erosion. Use the Decision Tool: Managing Runoff with Healthy Lakes & Rivers Practices to map your property, calculate runoff, and size and position Healthy Lakes & Rivers practices on your property.

Need some help?
Join us for a workshop about Managing Runoff with Healthy Lakes & Rivers Practices at the Wisconsin Lakes and Rivers Convention. We'll walk you through how to use the Decision Tool and help you find the right practice to meet your goals. You'll even get a chance to design your own rain garden in a fun activity!
