0The Minnesota Department of Natural Resources has confirmed the presence of zebra mussels in Union Lake, near Alexandria in Douglas County.
Douglas County invasive species staff found zebra mussels on a settlement sampler at the Union Lake public water access. Settlement samplers are solid surfaces temporarily placed in the water that people can regularly check for attached zebra mussels to aid in detection.
Union Lake is connected to, but upstream, of Burgen Lake, where zebra mussels were confirmed in 2017.
People should contact a Minnesota DNR aquatic invasive species specialist if they think they have found zebra mussels or any other invasive species that were not already known to be in the waterbody.
