Another option? Studying weevils' ability to control invasive species in Northwoods lakesSubmitted: 08/19/2014

BOULDER JUNCTION - The problem of invasive Eurasian Watermilfoil in Northwoods lakes never seems to stop.

Lake groups can cut it, but it often grows back.

Chemical treatments often work, but they put artificial ingredients into lakes.

What if there was another option?

We found one group on the hunt for one.

"We're on Boot Lake," Nick Winter says as we motor onto the water body near Eagle River.

The Lakeland Union High School graduate and current Minnesota-Duluth undergrad loves spending days on the lake.

"It's kind of fun to be around people that are as passionate about environmental problems as you are," he says.

Nick and two other college students are working on a study through the UW-Madison Trout Lake Station in Boulder Junction.

Everything they do revolves around creatures only a few millimeters long.

"A weevil is a small insect and it's aquatic, so it lives underwater," Susan Knight explains.

She leads the project, which studies what impact these weevils have on invasive Eurasian Watermilfoil.

"They burrow down into the stem and eat their way down the stem," Susan says. "As they're eating the stem, that is killing off at least the top of the plant."

On the boat, Nick helps put a handful of plants into a Ziploc bag.

"These are going to be the plants that we're going to use to search for weevils," he says.

Last year, thousands of weevils were set free in three test lakes.

Susan, Nick, and the team want to find out if they're effective in killing the invasive milfoil.

"It would be really nice to know that there is a biological control," Susan says. "Some means of control that is not chemical."

Besides just the sample stems, "we take a biomass sample," Nick explains, "so we go take a rake pull and get all of the biomass that we can off of that."

Then, all of the samples are shuttled back to the lab.

"We have a pan for all of the natives and a pan for just the Eurasian. They'll go into a big drying oven for a few days," Susan explains. "We think that weevils would be a success if we saw more natives and less Eurasian."

While part of the team weighs the dried biomass, others spend hours peering into microscopes.

"It's kind of a necessary evil," Nick says about the lab work, laughing. "This is where we get all of the important information for our study."

"They will examine those plants to see whether or not there are weevils at any life stage: eggs, larva, pupae, and adults," Susan says.

The team picks out and preserves samples of the insects in all four stages.

They're the focus of all of the effort leading up to what Northwoods researchers hope is a firm answer.

"If we could get a clear-cut result and say, weevils did or did not have any effect on the biomass, that would be ideal," Susan says.

They've still got plenty of data collection and number-crunching left to do before they find that answer.

But until then, on the water is not a bad place to spend a college summer.

"I feel like what we're doing is kind of like trailblazing," Nick says proudly. "It's a big project."

WAUSAU - Enthusiasm, excitement and surprises continue to pack the 2016 election season.

 Republican politicians in Wisconsin still have something to add to this election.  

On Sunday Governor Scott Walker, Senator Ron Johnson and Representative Sean Duffy all stopped by the Wisconsin GOP office. 

They came together to encourage voters to get out and vote early. 

About 30 people came out to hear what the politicians had to say.

"We need to convince people who maybe we don't know where their opinions are in terms of election," said Governor Walker.

 "But we work with them, we live next to them, we go to church with them those are the people we need to reach out [to]."

MINOCQUA - Every year thousands of kids go hungry. 

On Saturday nearly 600 volunteers from the Northwoods decided to help feed some of those children. 

The "Food for Kidz" organization, invited people to Lakeland Union High School, to help package non- perishable goods.

 The packages will be donated worldwide and to nearby food pantries.

Within the past eight years volunteers have packaged one million meals.

 Last year was the first year the organization started donating to local food pantries. 

This year volunteers will give 30,000 meals to the Northwoods community.

"It's just the recurring exuberance of the people that come in and do the packing we have many, repeat people that come year after year," said "Food for Kidz" Co-chairman John Breiten.

BOULDER JUNCTION - Nearby Fire Departments often rely on each other when they need extra man power. 

On Saturday firefighters from around the Northwoods came together as one. 
"It's vital to have that community bond between the fire departments," said Arbor Vitae Fire and Rescue Chief Mike VanMeter.

The bond between local departments led to a rare training opportunity. 

"Being able to share an opportunity like this is vital," said Boulder Junction Fire Department Chief Matthew Reuss. 

A donated house in Boulder Junction was lit on fire so that the fire departments could practice structure training.

RICE LAKE - The Merrill football team doesn't feel it got the respect it deserved when WIAA playoff brackets came out last weekend. The Bluejays shared a Great Northern Conference championship.

But they were pinned to a number 8 seed, the lowest in the bracket, and travel to face top-seeded Rice Lake in a Division 3 Level 1 game Friday night.

Recent history doesn't favor Merrill in the playoffs. It has lost six straight playoff openers, dating to 2009.
