Starry stonewort was confirmed on Thunder Lake in Cass County.
DNR staff was conducting a survey of algae in the lake near Remer.
The funding for this general algae research was provided by the Minnesota Environment and Natural Resources Trust Fund, as recommended by the Legislative-Citizen Commission on Minnesota Resources.
Starry stonewort has never been eradicated from any U.S. lake or river, but treatment and careful removal can help reduce the risk of spread and relieve starry stonewort’s recreational nuisances. Starry stonewort has now been confirmed in 23 water bodies in the state since first confirmed in Minnesota in 2015.
