Zebra mussel fears now surface in Alexandria
PAUL WALSH, Star Tribune
A live zebra mussel has been found in a popular western Minnesota lake, spreading the reach of the invasive species to a new part of the state, the Minnesota Department of Natural Resources said this afternoon.
The single zebra mussel was found this week on a coffee can in the northeast corner of Lake Le Homme Dieu in Alexandria, the DNR said.
The invasive species poses serious ecological and economic threats to any Minnesota lake and stream it finds. Heavy infestations can kill native mussels, harm fish populations, interfere with recreation and increase costs for industry, including power and water supply facilities.
Native to Eastern Europe and western Russia, zebra mussels were first discovered in Minnesota in 1989 in the Duluth harbor. They subsequently have spread to Lake Mille Lacs, Prior Lake and seven other inland lakes, and to portions of the Mississippi, St. Croix and Zumbro rivers.
DNR biologists intend to survey Lake Le Homme Dieu Friday and will designate it as infested if additional live zebra mussels are found.
This latest discovery also is prompting the DNR to remind boaters and anglers to take extra precautions in this region.
"As one of the larger lakes in the Alexandria area and connected to several other lakes, Lake Le Homme Dieu has significant boat traffic," said Luke Skinner, DNR invasive species unit supervisor. "Everyone needs to be extra vigilant to keep from spreading these pests to other waters."
Boaters are being encouraged to inspect and remove all visible aquatic plants, animals and mud from boats, trailers and equipment such as anchors before leaving a water access. They should also do the same to docks, boat lifts and swim rafts before transporting to another body of water.
Owners should also drain all water from boats - including live wells, bilges and bait buckets - before leaving a water access. Also, spray or rinse boats with high pressure and/or hot water, or let them dry thoroughly for five days before transporting to another body of water.
It is a misdemeanor to transport water or prohibited invasive species from designated infested waters.
