Aquatic Invasive Species
AIS (Aquatic Invasive Species) are plants, fish, invertebrates, and other creatures that are non-native to our lakes and rivers. Invasive species cause issues when they outcompete native animals and overwhelm their environment, with economic, environmental, and social ramifications. Each summer, Aitkin County hires AIS Watercraft Inspectors to check boats, docks, and other recreational watercraft for signs of invasive species. Aitkin County also has 3 decontamination units (decon units), which use hot or high-pressure water to clean and remove any invasive species that may be present on watercraft.
Zebra Mussels
Zebra mussels foul up boats, motors, docks, and equipment left in lakes. Zebra mussels can survive out of water for days, so it is critical to clean, drain and dry docks and watercraft before moving them to other lakes.
Starry Stonewort
Starry stonewort forms large, dense mats of vegetation that often outcompete native aquatic plants and impact boating, fishing, and other native animals.
Eurasian Watermilfoil
Eurasian watermilfoil is a feathery submerged aquatic plant that can quickly form thick mats that interfere with swimming and entangle propellers, which hinders boating, and fishing.
Flowering Rush
Flowering Rush shows dense growth along shoreland areas making it difficult to access open water. It overtakes habitat and outcompetes native aquatic plants, potentially lowering diversity. It does not provide suitable shelter, food, or nesting habitat for native animals.
Spiny Waterflea
Spiny waterfleas are microscopic animals, that live in open water. They are often found clogged on fishing line in gelatinous blobs.They harm food sources that our native fish depend on.
Decontamination Units
Are you leaving from an infested lake and want to clean off potential Aquatic Invasive Species?
​
Aitkin SWCD has 3 decon units that are available for the public to get their boats decontaminated by a trained Level 2 inspector.
​
One is housed at our office in Aitkin, one is housed at the Big Sandy Dam, and the third bounces around the Aitkin County lakes.

My name is Brian Roulet
I can assist in answering questions about our decontamination units, AIS in your lakes, and how to request funding from AIS Grants.
