Lake Koronis, like several other lakes in Minnesota, has been infected by two Aquatic Invasive Species (AIS). Our initiatives help to mitigate and reduce the spread of AIS so that our lake can be enjoyed for generations to come.

Aquatic Invasive Species

What is an Invasive Species? An invasive species is a non-native organism that could cause harm to the environment, economy, or human health after it has been introduced to an environment. They could be diseases, parasites, plants, or animals, including invertebrates and vertebrates. An Aquatic Invasive Species (AIS) is an invasive species that lives in a freshwater or marine environment.

What can be done? All invasive species have different ways they invade an environment, so each organism needs to be evaluated individually. But don't worry! Biologists, botanists, and AIS experts are hard at work every day finding solutions to help revitalize native species and limit the spread of AIS.

What can you do? There are many ways you can help prevent the spread of AIS and help your lake(s). First, please practice CLEAN DRAIN DRY. Always clean any equipment that goes in the water, drain any water that could have gotten in, and dry the equipment. Remember, Minnesota law requires that docks and boat lifts need to be out of the water for at least 21 days before they can be put in any another body of water.

Koronis Lake Invasive Species

Koronis Lake is home to many, beautiful native species, but some invasive species have found their way into our lake as well.

Starry Stonewort is an aquatic invasive species that has been under constant surveillance by the Lake Association and concerned parties. 

Zebra Mussels are small, invasive, fresh-water mussels. They are can be quite sharp and pose a risk to recreational activities.

AIS Control Tips

Learn to identify invasive species: Educate yourself about common invasive plant and animal species in your area to recognize and report any sightings.

Clean equipment and boats: Clean and inspect boats, fishing gear, and other recreational equipment to prevent the spread of invasive species. Remove any visible plants or animals and drain water from equipment before moving to a new water body.

Use native plants in landscaping: Choose native plant species for your landscaping projects. They are better adapted to the local environment and are less likely to become invasive.

Support local efforts: Participate in or support local invasive species removal programs or initiatives to help control and manage invasive species in your community.
