DASH Boat
Since 2019, Pretty Lake has run its own DASH (Diver Assisted Suction Harvester) to remove tons of invasive Eurasian Water Milfoil each summer. Left unabated, the invasive weed can eventually take over and adversely affect fishing and motorized boat navigation. Several tons of milfoil have been removed each summer season. And it has made a difference. A look at the most recent "point intercept survey" shows the sizeable reduction in milfoil "hotspots" between 2018 and 2024. Lake residents are encouraged to clean their own shorelines to avoid re-seeding of milfoil fragments. If you have any questions about how to identify and/or remove milfoil "by its roots", please contact Mark Bretl, who you'll find in the Pretty Lake resident directory.
