Clear link between littoral lake habitat and fishery quality explained
BOULDER JUNCTION - Most people wouldn't see a connection between trees and fish size.

But a UW-Madison researcher has drawn a pretty clear link.

Dr. Jereme Gaeta studied what's called the littoral zone of Little Rock Lake near Boulder Junction.

That's the area right near the shoreline.

He found warming temperatures lead to more lake evaporation.

Lakes then recede away from trees that would have fallen in the water.

Small fish lose their habitat, and food disappears for larger fish.

"The difference between lots of littoral habitat and no littoral habitat, in this case, is the difference between trophy fisheries, really healthy fisheries, and a population of stunted bass," Gaeta says.

Gaeta found it takes fewer than seven years for bass to reach legal length in lakes with plenty of wood in the water.

In lakes without that habitat, it takes 20 years.

Receding lake levels, and their impact on the littoral zone, are a newer idea for impacts of climate change in the Northwoods.

"Our study adds one little piece to that puzzle that we're trying to put together to understand what's going to happen as we look forward in a changing climate and a changing world," Gaeta says.

Gaeta's study came out of the 30-year split-lake study in Vilas County.

TOMAHAWK - A shooting in Tomahawk killed one person Thursday night.  Tomahawk Police Chief Al Elvins confirmed a male victim died after the shooting, which happened on West Mohawk Drive. Elvins wouldn't identify the victim or the suspect, who as of 7:45 p.m. police still had not found.

"I don't know the motive behind it, what triggered it, what was said. I have a detective now writing a search warrant. We have some evidence inside the house that we want to secure," said Elvins. "It appears to be an isolated incident." 

The chief did not believe anyone else is in danger.

RHINELANDER - Some Crescent Elementary students got their eyes checked Thursday.

But with some new technology, it only took a few seconds.

The Lions Club recently received a $7,000 eye screener from the Lion's Club District 27-C2.

The screener replaces the old way of having young kids read an eye chart, which is handy when some of the kids may be too shy or can't read the alphabet yet.

School District Nurse Kerri Schmidt says the technology doesn't work on adults but works well for the younger students.

LAONA - Spruce saplings his students planted decades ago have grown to tower above Don Kircher as he stands on a forest trail near Laona.

Kircher was a science teacher for 34 years in Laona, and he's visiting the Laona School Forest.

"The trees, of course, some of these trees are unbelievable," Kircher said.

The history of the forest itself might be hard to believe for some people. Little Laona has the nation's first school forest, dedicated in 1928. The Town of Laona bought the property and gave it to the school.
