Stop Aquatic Hitchhikers

Zebra mussels attach themselves to boats

Lake, LaPorte, and Porter County Residents: Help protect your lake from invasion!

Have you seen zebra mussels on docks, buoys, and bottoms of boats in lakes and ponds near your homes?

Have you found it difficult to navigate or fish in waters that are clogged with Eurasian watermilfoil?

Aquatic invasive species (AIS) can cause serious problems in inland lakes and ponds. They not only affect recreational access to waters, but also impact the region’s ecology and economy. AIS can be unintentionally spread among lakes by boaters, anglers, and recreational water users. We need your help to slow the spread of AIS! Illinois-Indiana Sea Grant (IISG) and the Northeastern Illinois Invasive Plant Partnership (NIIPP) are seeking volunteers to help raise public awareness about AIS and how to prevent their spread.

Volunteers will receive training at a two hour workshop and then pass along their new knowledge at boat ramps, marinas, and fishing tournaments during the boating season in Lake, LaPorte, and Porter Counties in Indiana. More information about the Stop Aquatic Hitchhikers! Clean Boats Crew program can be found at If you would like to volunteer in Indiana please contact Cathy McGlynn at or 847-242-6423.

Illinois-Indiana Sea Grant is a program of the University of Illinois and Purdue University that combines research, education, and outreach to empower southern Lake Michigan communities to secure a healthy environment by providing information about many environmental topics: aquaculture, coastal restoration, Great Lakes Health, water supply quality, aquatic invasive species, fish consumption, land use planning, and climate change. The Illinois-Indiana Sea Grant AIS outreach team is part of the Illinois Natural History Survey’s Lake Michigan Biological Station in Zion, IL.

More information about this program can be found at The Northeast Illinois Invasive Plant Partnership is a cooperative weed management area, a regional organization that brings together all interested landowners, land managers (private, city, county, state, and federal), non-profits, private entities, industry, special districts, and the public in the defined geographic boundaries of the Chicago Wilderness region for the purpose of coordinating and combining their resources, expertise, and activities for more efficient and effective management of invasive plant species across jurisdictional boundaries.
