Starry Stonewort Confirmed on 1 New Minnesota Lake
LOCATED AFTER A 20-COUNTY SEARCH
ST. PAUL, Minn. – After a search of 178 lakes in 20 counties by 200 trained volunteers, the Minnesota Department of Natural Resources has confirmed that the invasive algae starry stonewort in Grand Lake in Stearns County.
This is the first new confirmation of the species in a Minnesota lake in 2017.
DNR invasive species specialists confirmed a light, isolated growth of starry stonewort near Grand Lake’s public access.
“Although we were hoping to find no new populations, we are glad this one was discovered early, thanks to the people who participated in the coordinated search known as ‘Starry Trek,'” said Heidi Wolf, DNR invasive species unit supervisor. “We’re also encouraged that there hasn’t been a greater number of lakes found to have starry stonewort during this major search.”
Treatment options for the lake are currently being considered. To date, starry stonewort has not been eradicated from any lake in the United States.

The new confirmation has the DNR reminding boaters and anglers to follow Minnesota laws to prevent the spread of aquatic invasive species:

- Drain all water by removing drain plugs and keep drain plugs out while transporting watercraft.
- Dispose of unwanted bait in the trash.
