The Minnesota Department of Natural Resources has confirmed the invasive algae starry stonewort in Pleasant Lake, near Annandale in Wright County.
This is the second new confirmation of starry stonewort in Minnesota in 2018.
There are now 13 lakes in Minnesota where starry stonewort has been confirmed.
A DNR invasive species specialist confirmed starry stonewort when investigating a report of zebra mussels in Pleasant Lake, which turned out to be negative. Two small, dense patches of starry stonewort near the county-managed public access on the north side of the lake.
Staff from the DNR, Wright County and the Pleasant Lake Association are coordinating treatment.
Wright County officials have closed the public access until further notice.
