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 above is Flowering Rush (photo credit: Minnesota Wildflowers Website). This species has been found along the shoreline of three lakes within Le Sueur County. It is best to identify this species when flowering due to its resemblance to other aquatic species.
The picture to the left 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.
New Infestation in Le Sueur County!
Le Sueur County was recently notified by the Minnesota Department of Natural Resources (DNR) that Upper Sakatah Lake has a new infestation of Eurasian Watermilfoil which is an aquatic invasive species. The DNR will be completing surveys to determine the extent of where this species is located.
The next step for Le Sueur County is to remove the species which will likely occur this fall. If deemed necessary, a follow up treatment will be completed in the spring.
Please spread the word about this new infestation! We do not want Eurasian Watermilfoil to spread to any other bodies of water! Remember to Clean, Drain, and Dry your watercraft and water-related equipment!
