During the first week of June, a boat sprayed chemicals into the waters of Anvil Lake in Vilas County for the first time.
It was applying an herbicide called 2,4D, targeting Eurasian watermilfoil, an aquatic invasive species whose presence in the lake has grown and grown.
The decision to use chemicals in treating the problem was difficult and often controversial for lake leaders.
But it’s a decision more and more lake groups in the Northwoods are forced to consider as invasive species spread.
In many ways, Anvil Lake is where Dr. Amy Kuhns grew up.
