New invasive species infestations threaten local lakes

During a recent government meeting, officials discussed the ongoing challenges posed by invasive species in local lakes, highlighting four new infestations reported this year. Notably, starry stonewort was confirmed in the Whitefish chain on Rush Lake, while North Long Lake was deemed infested with Eurasian watermilfoil near the Merrifield Bay boat launch. Additionally, zebra mussels were discovered on a dock at White Sand Lake, marking a concerning trend in aquatic invasions.

The meeting emphasized the importance of monitoring these infestations as they will influence the planning for 2025. Officials noted that the traffic at landings and the nature of the infestations are critical factors in developing effective management strategies. The Department of Natural Resources (DNR) played a key role in identifying these species, with Rich Rosenga, an invasive species specialist, discovering the starry stonewort incident during a survey for curly leaf pondweed.

As the state grapples with these ecological threats, the discussions underscored the need for continued vigilance and proactive measures to protect local waterways from further invasions.
