Sixteen zebra mussels have been
found across a wide area of Christmas Lake, concluding a one-year effort to get
rid of the invasive mussels. Despite this unfortunate result, the
first-of-its-kind response yielded a number of important discoveries and lessons
that will help future attempts to control zebra mussels.
The rapid response at Christmas Lake, where zebra mussels were first discovered
in August 2014, was a joint effort between the Minnesota DNR, MCWD, Minnesota
AIS Research Center, City of Shorewood and Christmas Lake Homeowners
"There is no playbook for how to respond to a new zebra mussel infestation
-- we are writing the playbook as we go," said Eric Fieldseth, MCWD AIS Program Manager. "While it is unfortunate the zebra mussels weren't
contained, this effort made a huge contribution to the field of zebra mussel
The Minnehaha Creek Watershed District (MCWD) is committed to a leadership role in maintaining and enhancing the integrity of the District's water resources. This section of the website will help you understand what you can do individually, and what we are doing collectively through government agencies, to prevent AIS at bay in our watershed.
The presence or introduction of aquatic invasive species (AIS) threatens the quality of aquatic ecosystems. AIS decrease recreational opportunities, alter the food chain and quality of fishing, decrease property values, and increase the private and public costs of managing and controlling their presence.
Most invasive species present today have been introduced by human activity, including:
Accidental release from contaminated waterbodies, via boats, docks or other equipment
Accidental release from contaminated or mislabeled bait
Aquarium hobbyists and water gardeners dumping fish and/or plants into a waterbody
Sadly there is no safe technique to get rid of
most AIS once they’re established. While researchers work on long-term solutions,
the only way to keep them out of our waterways is for Minnesotans to pitch in and
take responsibility for their own equipment. If we all take a few small steps
to avoid infesting new waters, we can hopefully stop AIS from
