People come from all over the state and country to visit the great Northwoods town of Minocqua.
That’s why it’s vital the area’s lakes and rivers stay clean and free from invasive species.

Again this year, aquatic invasive species are a concern among the Department of Natural Resources and nature lovers.

Major predators include Eurasian water-milfoil, purple loosestrife and zebra mussels.

"It's a huge issue because up here we depend on tourism and keeping our lakes nice and clean, because people come up here to boat, fish, go swimming,” said DNR Deputy Warden John Preuss.

The conservation warden urges boaters and anglers to clean off their boats when they come off the lake.

It is also important to drain water from the boat, motor, bilge, live wells and bait containers before leaving the landing area.

Thorough cleaning is vital, since many types of invasive species are tiny and can not be seen with the naked eye.
