Although many people associate these stone-like animals with the crystalline waters of the tropics, several species of sponges do occur in lakes and ponds across North America, including those of western Montana.

The bottom of this shallow stream is covered with a complex community of algae, comprising many different species. Probably most abundant of all are the diatoms, many of which secrete a slippery mucus as they travel, leaving the rocks very slick.

Fish, and maybe you, are getting stressed out in this summer heat. But for fish, stress is made worse when, on top of trying to stay cool, they have to avoid eating a fly tied to a line.

In the heat wave of the past few weeks, guides and regulators have worked to protect fish during a time when fish are very vulnerable.

It will take more time before we learn about potential cleanup options at a former paper mill in Frenchtown.

Today was the Environmental Protection Agency's original deadline for the site's prior and current owners to present a "good faith" cleanup offer. The plant was in operation since the 1950’s. It was most recently owned by the Smurfit-Stone Container. The plant closed in 2010 and was purchased by M2 Green Redevelopment in 2011.

A new study on the probability of more landslides at the Berkeley Pit Superfund site in Butte will be made public soon.

Last week Silver Bow County commissioners got a tour of the Butte Superfund site, led by Steve Walsh, an executive with Montana Resources. That company is actively mining for copper and molybdenum at the Continental Pit in Butte, but has operations at Berkeley Pit as well.

From a point high on the Berkeley Pit’s rim, Walsh pointed out where the company used to be more active there until last year.

Two people have been arrested and two others are wanted in connection to the Missoula Sheriff Department’s investigation into the death of Gilbert George Berry, whose body was found in the Clark Fork River Tuesday.

Officials say Kevin Joseph Lino, 27, is wanted for the charge of deliberate homicide, and are searching for Angela M. Marchese, also 27, who is a witness in the case.

Lino and Marchese are believed to be traveling in a white 2014 Ford Focus, with a temporary West Virginia Plate. 

The Sheriff's Office believes Lino is armed and dangerous.

The Missoula County Sheriff's/Coroner's Office has identified the victim of yesterday's river recovery as 71-year-old Melvin Arthur Beedle.

The Montana Department of Environmental Quality announced this week the first phase of the Clark Fork River cleanup near Warm Springs is mostly complete.

In this feature interview with Edward O'Brien, D-E-Q Director Tracy Stone-Manning, says this first of the 15-year project was a tremendous success.
