The Minnesota Department of Natural Resources has confirmed Minnesota’s third and fourth cases of the invasive algae, Starry Stonewort, found this time in Upper Red Lake and in Cass Lake within the Leech Lake Reservation.
On Upper Red Lake, DNR staff confirmed a heavy growth of Starry Stonewort in a private harbor at eastern edge of the lake and are working with the property owner, local government and tribal officials to determine treatment options.
The invasive algae had previously been found in Turtle Lake, near Bemidji after first being discovered last summer in Lake Koronis near Paynesville, where the Koronis Lake Association began treatment last week, with a machine used to remove the largest growth of Starry Stonewart.
Here in the listening area, the DNR is asking boaters to take every precaution to keep the infestation from spreading. That includes cleaning aquatic plants and matter from watercraft, removing drain plugs to rid the craft of all water and keeping plugs out while transporting, and finally, disposing of unwanted bait in the trash, not in state lakes or other waterways
