Water sample reveals zebra mussel larvae in Ten Mile Lake in Cass County
Web posted November 5, 2019
The Minnesota Department of Natural Resources has confirmed zebra mussel larvae in a water sample taken from Ten Mile Lake near Hackensack in Cass County.
A DNR research scientist identified 17 microscopic zebra mussel larvae, called veligers (VEL-uh-jers) in a water sample taken from the lake in September. While no adult or juvenile zebra mussels have been reported, the number of veligers indicates a reproducing population.
Ten Mile Lake will be added to the infested waters list for zebra mussels, so that people who harvest bait, fish commercially or appropriate water take necessary precautions. Other lake users should follow the same "Clean, Drain, Dispose” steps that are always legally required on all water bodies, regardless of whether they are on the infested waters list.
Lake property owners should carefully check boats and trailers, docks and lifts, and all other water-related equipment for invasive species when removing equipment for seasonal storage.
It is especially important to follow Minnesota’s law and keep docks and boat lifts out of the water for at least 21 days before putting them into another body of water.
Anyone transporting a dock or lift from a shoreline property to another location for storage or repair may need a permit, to help prevent the spread of aquatic invasive species.
