BP: Zebra mussels confirmed in two Minnesota lakes

MOORHEAD — The Minnesota Department of Natural Resources has confirmed zebra mussels in Grants Lake in Douglas County and West McDonald Lake in Otter Tail County.

During a treatment operation for a recently confirmed small population of the invasive plant flowering rush in Grants Lake, specialists from Douglas County and the DNR found multiple zebra mussels on a settlement sampler hanging on a dock. Settlement samplers are solid surfaces placed in the water that people can regularly check for attached zebra mussels.
