An Otter Tail County Lake is one of two Minnesota lakes recently confirmed to be infested with zebra mussels. The Minnesota DNR has confirmed West McDonald Lake in Otter Tail County and Grants Lake in Douglas County have zebra mussels.

According to the DNR, following a credible report of a single adult zebra mussel in West McDonald Lake last month, DNR divers searched three areas of the lake. They examined more than 2,000 objects in the lake and did not find zebra mussels. During a follow-up search, DNR divers found two zebra mussels about 700 feet from the location of the original report.

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.

On all lakes and rivers in Minnesota, Minnesota law requires boaters and anglers to clean watercraft and trailers of aquatic plants and prohibited invasive species. Drain all water by removing drain plugs and keeping them out during transport, and dispose of unwanted bait in the trash.
