WINNIPEG (KFGO AM) Manitoba officials have found zebra mussels in Lake Winnipeg. Province conservation biologist Laureen Janusz tells KFGO News it's still a mystery how they got there. She says they're looking at a couple of possibilities -- either by infested watercraft or equipment or through the Red River from North Dakota where mussels have been found in the past.
North Dakota Game & Fish Department invasive species coordinator Fred Rykman says initial testing didn't find any trace of the mussels in the Red River this year but more water samples are being analyzed at a Montana lab. He says he wouldn't be surprised if some turn up.
Immature mussels were found in the Red River in 2010 and 2011 near Wahpeton and are found upstream on the Otter Tail River and the lake chain in western Minnesota.
