An Angler's Winter and Other Laments

Last night it snowed for the first time, everything's covered in white. How many months till the springtime? It's a long winter's night

This winter has been especially tough for me with the seemingly endless nights and non-stop rain or snow. It put's on darkness on my moods that only the warmth of spring and summer can cure.
Part of it's been the fact that my beloved mother-in-law is no longer with us. She was the matriarch of the family and I never realized how much affection I had for her until she was gone. It's just not the same nor will it ever be but for the passing of time to heal the loss our family feels.
Secondly my fishing is not very adaptable for the winter. The trout don't rise after hatches that are not there because it's too cold.
My fly rods sit snugly in their cases and every once in awhile I'll take them out just to feel them in my hand. I know it's just a matter of a few months until the days are long enough and warm enough to venture over the mountains to seek the red sides of the Deschutes.
Oh I'll get out with my gear chucking friends and even fish some deeply swinging flies on a coastal river but it's not the same.
So with enthusiasm I will look to the coming spring with hope and anticipation.

Contamination leading to decline of Yellowstone Cutthroat Trout in Idaho

Once again man's greed and interference with the environment is exacting a heavy toll. This time with the endangered Yellowstone Cutthroat trout.

BOISE, Idaho -- Two of the West's largest remaining populations of Yellowstone cutthroat trout face sharp declines due to contamination from phosphate mines in southeast Idaho, Idaho State University professors say.

Rob Van Kirk, a professor who specializes in mathematical models of aquatic ecosystems, and Sheryl Hill, a biology professor, on Thursday released a study that predicts a precipitous fall of the prized game fish in some streams and an overall decline in populations in the region.

They said contamination comes from selenium leaching out of waste rock from the mines.

Selenium is a naturally occurring mineral that is healthy in small quantities but can build up to toxic levels. At phosphate mines, it leaches out of waste rock and accumulates in stream sediments, where it goes through the food chain from plants to insects to fish.

"The bottom line is there are (selenium) concentrations in fish that are high -- high by anyone's standards, not just cherry picking standards -- and that indicate a high risk of population declines," Van Kirk said.

The Bozeman, Mont.,-based Greater Yellowstone Association -- whose stated mission is to protect the lands, waters, and wildlife of the Greater Yellowstone Ecosystem -- paid the university about $8,600 to produce the report.

The organization is trying to collect expert data on how phosphate mines are effecting fish and wildlife, spokesman Marv Hoyt said.

The Blackfoot and Salt river drainages in southeast Idaho contain two of the six largest remaining populations of Yellowstone cutthroat, Van Kirk said.

The population has already suffered major setbacks in what was its main habitat, Yellowstone National Park, following illegal introduction of lake trout to Yellowstone Lake. In February, the U.S. Fish and Wildlife Service declined to list the species, though the selenium threat was considered.

"There were some concerns that were identified," said Wade Fredenberg, native fish coordinator with the wildlife service. "I don't want to trivialize it, because in those drainages it might be serious, but the point is we're not going to cease phosphate mining in every drainage that contains Yellowstone cutthroat trout."

Southeast Idaho contains large formations of phosphate rock. Phosphate is used for agricultural chemicals and fertilizer. Mining began in 1907 and increased significantly after World War II.

According to the coalition, the area has three operating phosphate mines and up to 26 closed mines. The main operators are Boise-based J.R. Simplot Co., Monsanto Co. in St. Louis and Agrium Inc. of Calgary. All three supply agricultural products to growers.

Fred Zerza, a Simplot spokesman, said the report from ISU was one of several designed to derail the company's planned expansion of its Smoky Canyon mine.

"This would be another in a succession of those," Zerza said, "to discredit the efforts of the company to develop the mine."

He said the company has made efforts to control selenium contamination with water and fish monitoring systems as well as rerouting one stream away from waste rock.

Researchers found that fish in the Salt and Blackfoot drainages contained an average 9.81 micrograms of selenium per gram of body weight, which they say is more than 2 micrograms above the point where fish populations start declining.

Of the 63 fish samples that looked at selenium levels, Van Kirk said most were taken in 2005 and 2006. The samples ranged from 1.8 micrograms up to 52.3 micrograms.

Four streams had concentrations above 20 micrograms, Van Kirk said, including East Mill Creek, a tributary to the Blackfoot River.

The Idaho Department of Health and Welfare has warned parents to limit the number of fish children eat from the creek because of the high selenium concentrations. But Van Kirk said selenium has killed most fish in that stream.

Three other streams that contained fish with levels above 20 micrograms were Sage, Deer and Crow creeks, all tributaries to the Salt River.

"It's scary," said Trout Unlimited Chris Hunt, based in Idaho Falls. "It's scary for us over here. These fish are the backbone of our fishery, up and down the east side of the state."

Van Kirk said more field work is needed.

"One of the requirements is that we get out and do some careful and well designed monitoring of the populations in the field," he said. "My guess is there is a lot more selenium that will continue to go into these streams."
