MINNEAPOLIS — An invasive aquatic plant known as Eurasian watermilfoil has been found in northern Minnesota’s Hubbard County for the first time.

The state Department of Natural Resources confirmed the plant in Bad Axe Lake near Emmaville. Officials say it was found around the resort access to the lake and doesn’t appear to be widespread.

The plant can interfere with recreation by forming mats on the water surface, and it can displace native plants and alter aquatic ecosystems. It can be treated with herbicides but is difficult to eradicate.

This story has been corrected to show the lake is named Bad Axe Lake, rather than Big Axe Lake.
