ST. PAUL (AP) -- Eurasian watermilfoil has been found in North Twin Lake near Grand Rapids and in five Twin Cities-area lakes, the Department of Natural Resources reported Monday.
The 250-acre North Twin Lake is the third lake in the Grand Rapids area known to be infested with the harmful exotic plant. A two-acre affected area has been treated with an aquatic herbicide.
Milfoil also was confirmed in Deer and Goose Lakes in Wright County, Lake Owasso and Kohlman Lake in Ramsey County, and Green Lake in Isanti County, the DNR said. Green Lake is the first lake known to have milfoil in Isanti County.
So far, 112 Minnesota lakes are infested with the plant, which crowds out native vegetation.
