Christmas Lake treatment update The fight to eliminate a small infestation of zebra mussels in Christmas Lake continued on June 26. The DNR and MCWD cordoned off an 11-acre area on the north end of the lake and treated it with potash (potassium chloride), an effective agent for killing zebra mussels. The treatment will last about two weeks and the public launch is planned to re-open July 10.
The DNR is also planning to replace the boat launch during the time it is closed. The launch had already been scheduled for replacement this year.
This work comes after the DNR and MCWD treated a smaller area around the public launch over the winter. The treatment appears to be effective, as no zebra mussels were found in the treatment area. However, a handful of zebra mussels were discovered just outside the barrier, and were removed. By greatly expanding the treatment area, the groups hope to fully eradicate any mussels that survived the initial treatment.

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
