Zebra Mussels Reported on Two Minnesota Lakes
Lake John has broad infestation; One zebra mussel found on Bryant Lake
St. Paul, MN -(AmmoLand.com)- The Minnesota Department of Natural Resources has confirmed a report of zebra mussels in Lake John, in Wright County.
A citizen involved in a monitoring program reported a single zebra mussel in late September, but subsequent surveys revealed a more widespread and established infestation throughout much of the lake. The lake is not a candidate for current treatment methods because the infestation is widespread. Lake John has been added to the infested waters list. Other bodies of water connected to Lake John may also be added to the infested waters list after further assessment.
In another case, a single zebra mussel was recently reported in Bryant Lake in Eden Prairie. Three Rivers Park District staff discovered the invasive species on a settlement plate, a simple underwater detection device placed around docks and shorelines, and reported it to the DNR.
Extensive dive searches over the next several days revealed no additional zebra mussels in the lake. DNR invasive species specialist Keegan Lund said Bryant Lake will be carefully monitored the rest of this season and next year, but no treatment is necessary at this time.
The combined efforts of the DNR, lake property owners and lake users to spot and report suspected new infestations increase the chances of treating them or limiting their spread. This time of year it is especially important to check docks, lifts, and other equipment for zebra mussels. By law, docks and lifts must also dry for at least 21 days before putting them into another body of water.
“There is a common misconception that zebra mussels ‘are everywhere’ and that their spread is inevitable. The reality is, zebra mussels have been confirmed in less than two percent of Minnesota lakes, and more Minnesotans than ever before know and follow invasive species laws,” Lund said. “People spread zebra mussels, and people can prevent the spread.”
Before leaving a lake, Minnesota’s aquatic invasive species laws require boaters and anglers to:
- Clean aquatic plants and animals from watercraft.
- Drain all water by removing drain plugs and keeping plugs out while transporting watercraft.
- Dispose of unwanted bait in the trash.
