New Infestation

Le Sueur County has set aside AIS Prevention Aid funds for new infestations/introductions of Aquatic Invasive Species that are found within the County.  Early detection and management is crucial to minimize the spread and impacts of the new infestation/introduction within a body of water and to surrounding bodies of water.

Recently, Le Sueur County has utilized AIS funds to address new infestations of Eurasian Watermilfoil in Lake Tetonka and Lake Francis.

The picture to the right is Eurasian Watermilfoil (EWM) that was removed from Lake Francis in the fall of 2018.  This was a continued effort to control an EWM infestation that began in 2017.  Hand removal was selected due to the healthy population of native aquatic vegetation that resides in Lake Francis.
