How salmon can transform a landscape

Protecting salmon in coastal Canada could have benefits that extend beyond the water they swim in and can have profound impacts on the surrounding landscape.

Skeins of wispy clouds obscure the tops of distant forested mountains, reflected in calm waters. On this midsummer morning at least, the Pacific is living up to its name on this stretch of Canada’s west coast. Backpacks and thermoses in hand, four researchers tread down a wooden strutted ramp to board a boat named the Keta. Scientist Allison Dennert starts the boat, steering away from the dock into the broad channel, glancing at the map on the video console. A brief stop at the Bella Bella dock, to pick up research technician Sarah Humchitt, completes our crew of five.

Washington state to regulate federal dams on Columbia, Snake to cool hot water, aid salmon

Dams and climate change are the leading cause of high temperatures in the Columbia and Snake rivers that are killing salmon, according to an EPA draft analysis. Now the state wants to get involved.

Summer temperatures in portions of the Columbia and Snake rivers are up by 1.5 degrees Celsius since 1960 because of the combined effects of climate change and dams, according to a new draft analysis by the U.S. Environmental Protection Agency (EPA).

Where are the kokanee? Only 60 to 70 fish counted in local creeks compared to nearly 6,000 a year ago

The Issaquah Press ~

Before emerging from the creek on a cold, sunny December morning, Dan Lantz pulled out a notebook to record a very familiar number this kokanee spawning season — zero.

Lantz, an environmental scientist for King County, and other fish ecologists were expecting a low return of kokanee this year. Spawning runs are typically cyclical, with boom and bust years. But nobody expected the numbers to be this bad.

SPOKANE, Wash. — A federal judge is forcing discussion of a radical step to save endangered salmon: taking out four dams on the Lower Snake River.

Eroded Elwha River beach transformed after armoring removed

PORT ANGELES — It didn’t take long for a half-mile section of eroded beach to be transformed after derelict armor was removed east of the Elwha River mouth.

River Revives After Largest Dam Removal in U.S. History

In August 2014, workers completed the largest dam removal project in U.S. history, as the final part of the 210-foot-high (64-meter-high) Glines Canyon Dam was dismantled on the Elwha River in northwestern Washington State.

The multistage project began in 2011 with the blessing of the U.S. National Park Service, which administers the surrounding Olympic National Park. The goal was to remove unneeded, outdated dams and restore a natural river system, with presumed benefits for fish and other wildlife.

U.S. judge tosses feds' salmon plan back in water, suggests breaching dams

5/5/2016

Seattle PI -

Once-mighty Columbia River and Snake River salmon runs are in a "perilous state" and U.S. government restoration efforts are "failing," a U.S. District Court judge said in a tough opinion released Wednesday.

Judge Michael Simon threw out the feds' latest plan for managing the Northwest's greatest river system.

The 149-page ruling by Simon is the fifth time courts have rejected federal plans as flawed or inadequate under the Endangered Species Act and the National Environmental Policy Act.
