ST. PAUL, Minnesota — The Minnesota Department of Natural Resources says zebra mussels have been confirmed in a lake in Morrison County.
The agency said Monday the invasive pest was confirmed in Fish Trap Lake near the town of Motley.
On June 30, someone using the lake reported a zebra mussel attached to a submerged tree branch near shore. A DNR aquatic invasive species specialist confirmed it was a zebra mussel.
DNR staff surveyed the lake Thursday and found an established population of adult zebra mussels in widespread areas of the lake. The agency says the infestation would not be a candidate for treatment.
Fish Trap Lake is the first lake in Morrison County to be confirmed with zebra mussels. The central Minnesota lake will be designated as zebra mussel infested.
