Starry stonewort confirmed in Lake Bemidji

Starry stonewort was confirmed in Lake Bemidji.

The Minnesota DNR says staff found the invasive macroalgae while conducting a general survey of algae in the lake.

Starry stonewort has been previously confirmed in other nearby lakes. Follow-up surveys are being conducted to determine the extent of the infestation.

Starry stonewort has never been fully eradicated from any U.S. lake or river, but treatments and careful removal, such as hand pulling and herbicide applications, can reduce the risk of spread and relieve associated nuisance impacts on water-related recreational activities.

Starry stonewort, since it was first confirmed in the state in 2015, has been found in 22 water bodies in Minnesota.
