RIVERS — Aging dams threaten fisheries in portions of the Columbia River and a proposed copper mine threatens headwaters of Montana's Smith River, putting them both on a conservation group's 2015 list of "10 most endangered rivers."
“We choose rivers that face key decisions in the next 12 months,” said Scott Bosse, American Rivers Northern Rockies Region director. “With the Smith, the mining plan is expected to be filed in late 2015, so there will be a critical decision point in the first half of 2016. We’re asking people to contact Gov. (Steve) Bullock and ask him to direct state agencies not to permit the proposed mine unless it can be constructed in such a way it doesn’t pose a threat to the fisheries there.”
The Smith made the list because of the potential for Canada-based Tintina Resources Inc. opening a copper mine on 12,000 acres of land along Sheep Creek. That stream is a major trout-spawning tributary of the Smith.
The rest of the 2015 list includes the Columbia River through Oregon and Washington where negotiations for revising the Columbia River Treat hold the key to more fish passage posibilities.
Other rivers: the Holston River in Tennessee (toxic chemical pollution), Edisto River in South Carolina (excessive water withdrawls), Chuitna River in Alaska (proposed coal mine), Rogue-Smith watersheds in California (proposed nickel mines), St. Louis River in Minnesota (copper/nickel mine), the Harpeth River in Tennessee (sewage pollution), and the Pearl River in Louisiana and Mississippi (proposed dam).
American Rivers estimated the Smith generates about $4.5 million a year for outfitters and surrounding communities, mainly from floaters traveling its 60-mile-long limestone canyon section between the Little Belt and Big Belt mountains. Fishing and camping along the Smith have become so popular, the state Fish, Wildlife and Parks Department has had to impose a lottery permit system to control overuse.
According to the Missoulian, Montana rivers previously on the American Rivers list included the North Fork of the Flathead shortly before Congress agreed to a transborder protection act prohibiting mineral development on the American and Canadian sides of the river, along with the Blackfoot, Kootenai and Yellowstone rivers.
American Rivers is the nation’s largest river conservation group. It has been releasing its endangered river list since 1984.
FISHERIES — A new study says a metal-like element called selenium is leeching from coal mines into the Elk river drainage in southeastern British Columbia, threatening fish habitat in Canada and downstream in Montana.
The study found five coal mines in the Elk River Valley are causing toxic pollution, and four of the coal mines are planning expansions.
The Missoulian reports a new coal mine proposal and three exploration projects are also under way.
The executive director of a conservation group called Wildsight says the selenium affects reproductive organs in fish and could lead to a population collapse.
The Elk River joins the Kootenai River at Lake Koocanusa.
The study was commissioned by Glacier National Park and carried out by the University of Montana’s Ric Hauer and Erin Sexton.

FISHING — Warmer water temperatures being recorded in North Idaho streams and rivers are creating unhealthy conditions for trout, especially the region's westslope cutthroats, Idaho environmental officials said.
A recent analysis by the Idaho Department of Environmental Quality shows that nearly 900 miles of streams in Kootenai and Shoshone counties are reaching temperatures up to 80 degrees in warmer months, well above the optimal temperature of 55 degrees or colder for trout species that attract legions of fly fishers.
The biggest factor to the warming trend is excessive sun exposure and lack of tree cover that provides shade and protection, Kajsa Stromberg, DEQ spokeswoman, told the Coeur d'Alene Press in a story published Tuesday.
In addition, Forest Service and Idaho Fish and Game studies over the years have documented major losses of deep holes and stream structure trout would seek to survive such conditions. Historic mining, logging and road-building practices contributed to the problems.
The region most affected by the warmer waters is the North Fork Coeur d'Alene River Sub basin, a region with a national reputation for producing great cutthroat trout fishing.
The warmer temperatures have a variety of negative impacts on trout, from making the fish lethargic to heightened risk and exposure to potentially threatening disease.
THE GOOD NEWS is that the DEQ is proposing a plan to lower water temperatures and improve access to colder, deeper waters to help reverse the warming trend.
- The strategy includes building more rock structures and logs to narrow and deepen channels and improving access fish have to cold-water channels and natural springs. The plan, now open for public review and comment, would also protect more of the region's shoreline trees from timber harvest managed by the U.S. Forest Service and provide incentives to private landowners.
The agency is taking written comments on the proposal until April 10, followed by a public hearing. The agency will also submit its draft plan to the Environmental Protection Agency for review.

THE BAD NEWS is that the online reaction to the CdA Press story on this issue was dominated by comments suggesting the DEQ's proposal is an example of government waste or a "liberal" reaction to climate change.
God help us if such ignorance is allowed to guide our stewardship of natural resources.
FISHING — Native cutthroat trout are likely to feel the heat from climate change.
A new study shows a changing climate could reduce suitable trout habitat in the western U.S. by about 50 percent over the next 70 years, with some trout species experiencing greater declines than others.
The results were reported by a team of 11 scientists from Trout Unlimited, the U.S. Forest Service Rocky Mountain Research Station, Colorado State University, the U.S. Geological Survey and the University of Washington Climate Impacts Group.
The study, published today in the peer-reviewed science journal Proceedings of the National Academy of Sciences, predicts native cutthroat throughout the West could decline by as much as 58 percent, while introduced brook trout could decline by as much as 77 percent. Rainbow and brown trout populations, according to the study, would also decline by an estimated 35 percent and 48 percent respectively. (Read the study report.)
The study notes that the decline of cutthroat trout is “of particular significance,” because cutthroats are the only trout native to much of the West and a keystone species in the Rocky Mountain ecosystem.
