KOSCIUSKO — Zebra mussels are a consistent problem in Kosciusko County. Fortunately, prevention is fairly straightforward. As you gear up for summertime on the lake, you can also prepare to help stop the spread of invasive species.

What are zebra mussels?

Zebra mussels are invertebrate animals that are known for their triangle-shaped, black-and-white striped shells. These invasive mussels have small tufts that allow them to attach to hard surfaces, including piers and other mussels.

Zebra mussels colonize by layering upon each other, effectively clogging pipes and killing other native species, like clams. Zebra mussels are picky eaters, preferring to snack on helpful algae rather than harmful algae. We definitely don’t want them in our lakes.

How can you prevent the spread of zebra mussels?

Here are two ways you can help keep zebra mussels out of our lakes:

• After boating in a lake or pond, remove plant fragments and mud by rinsing your boat, propeller, trailer and all other water equipment. This helps prevent transfer of bacteria and algae from one lake to another.
• When possible, allow your equipment to dry completely — five days is ideal — before transporting it into a new body of water. Mussels and bacteria can’t survive long without water.

You can also help prevent invasive species by supporting the Lilly Center’s work. This summer, using 100 specially designed samplers, we will gather data about zebra mussels from 30 to 40 testing sites throughout the county. After we compile the numbers, we will share the data directly with you.

The Lilly Center for Lakes & Streams at Grace College conducts research, provides resources, engages and educates residents, and collaborates with local organizations to make the lakes and streams of Kosciusko County clean, healthy, safe and beautiful. To date, the Lilly Center has conducted scientific research on over 30 streams and 40 lakes. The Lilly Center is driven to create a legacy of stewardship by equipping community members, visitors and future generations to understand and enjoy the county’s natural beauty.
