Protecting Our Lakes
Minnesota is the home of 10,000 lakes, and Shorewood has quite a few of our own. To protect Minnesota waters it takes a village. We all must work together to do the right thing to keep our lakes, streams, wetlands, and rivers clean.
10 zebra mussels found in Christmas Lake
Teams of divers this week found a total of 10 zebra mussels in a second search of Christmas Lake. None of the 10 were found in the area treated late last year, the Minnesota Department of Natural Resources said.
The 10 zebra mussels were removed from the lake, and monitoring will be ongoing. The DNR will review all data collected and determine whether any further response is feasible and necessary. A search in April indicated successful treatment of a small, isolated infestation of zebra mussels that was detected early. However, the more extensive shoreline and underwater dive searches Wednesday and Thursday revealed the invasive species was present in very small numbers outside the treatment area. The searches were organized by the Minnehaha Creek Watershed District (MCWD), with divers from the DNR, MCWD, Blue Water Science and Waterfront Restorations, and the University of Minnesota.
Zebra mussels are an invasive species that can crowd out native mussels and compete for food sources with other aquatic animals such as larval fish. They attach to boat hulls and other water-related equipment, can create a hazard for swimmers due to their sharp shells, and can pose a significant challenge for water intake operators.
Prevent the Spread of Aquatic Invasives
Before leaving a water access, boaters are required to:
- Clean off all aquatic plants and animals.
- Drain all water from bilge, livewell and baitwell by removing drain plugs and leaving the drain plug out when transporting.
- Dispose of unwanted bait in the trash.

Christmas Lake Public Access Now Open
The public access boat ramp at Christmas Lake is open daily 6 am-10 pm through the boating season. Inspectors will be on duty during open hours to inspect boats for aquatic invastive species. To ensure that you pass the inspection and are able to launch your boat, please make sure you follow DNR recommendations. If you have questions, please contact the city at 952.960.7900. If there is an after hours problem with the gate, please call 952.960.7914 and press 2.
Success With Zebra Mussels in Christmas Lake
Eleven days after Zequanox® was applied to an area around the Christmas Lake public boat access in Shorewood, it appeared it may have resulted in 100 percent mortality of the zebra mussels in the treatment area. Zequanox, a non-chemical treatment that has been federally approved for open water use, was applied to a 50 by 60 foot containment area on September 8. As of September 19, Minnehaha Creek Watershed District (MCWD) staff did not find any live mussels in the treatment zone. The combination of Zequanox and the near-total removal of dissolved oxygen caused by the treatment appear to have killed virtually all of the zebra mussels in the containment area.
AIS Ordinance for Christmas Lake
|The Aquatic Invasive Species (AIS) Ordinance covers watercraft entering Christmas Lake from the public access boat launch. The ordinance requires all watercraft entering the water to go through an AIS inspection. The inspection is provided at the public boat launch for no charge. Boaters may refuse to have an inspection and not enter the water.|
Should a boater refuse inspection and enter the water they are subject to a fine of up to $1000 and up to 90 days in jail. The ordinance was enacted in an effort to protect the waters of Christmas Lake from zebra mussels, which have been found in many Minnesota lakes including Lake Minnetonka. Questions regarding the ordinance may be referred to Planning Director Brad Nielsen, 952.960.7912.
