Christmas Lake zebra mussel treatments appear successful
Following a multi-agency response to the discovery of zebra mussels in Christmas Lake last August, results of initial searches indicate treatments were effective. On April 13, divers from Blue Water Science and Waterfront Restorations conducted a thorough survey inside and directly outside the treatment area around the public boat access in the City of Shorewood and found no evidence of zebra mussels. Subsequent monitoring of the lake will be necessary to confirm whether or not zebra mussels are present in other areas of the waterbody.
“We are encouraged by these early results,” said Keegan Lund, DNR AIS Specialist. “We used every available tool to treat the isolated zebra mussel infestation and learned valuable information in terms of responding to new zebra mussel infestations”.
Minnehaha Creek Watershed District’s (MCWD) aggressive early detection monitoring effort led to the discovery of zebra mussels near the Christmas Lake public boat launch in Shorewood on August 16, 2014. In coordination with the DNR and the City of Shorewood, the affected area was cordoned off and treated with Zequanox ®, followed by a copper-based product and then potash.
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
