Invasive Species Management


The Lake George Park Commission coordinates an annual Eurasian watermilfoil management program, in concert with its nonprofit partners the Lake George Association and the Fund for Lake George.  Milfoil was first discovered in Lake George in 1986, and it has been managed to varying degrees over the past 30 years.  More than five million dollars has been spent over this time to control the aggressive growth of this invasive plant.

Within the past five years, milfoil control has been taken up much more aggressively by the project partners, in an effort to eliminate all dense milfoil beds in Lake George for the first time since its discovery in the 1980’s.  Thanks to recent additional funding from the NYS Department of State through Warren County, this goal seems closer than ever.  By year 2021, with all partners working together, we believe that the days of dense milfoil beds in Lake George will be a thing of the past.  Please take a look at the annual Eurasian watermilfoil reports for more information.

Please report any new milfoil sites to the Lake George Park Commission, at 518-668-9347.
