This week the Elwha River – on Washington’s Olympic Peninsula – will flow freely once again. Two dams blocked the river for more than 100 years.

But thanks to the largest dam removal project in U.S. history, the lower dam is completely gone and the last 30 feet of the upper dam should be blown up Tuesday.

Our EarthFix reporter, Ashley Ahearn, headed out to the Elwha and reports that the river is returning to life.

Washington Governor Jay Inslee has just released a new plan to improve water quality in the state. One measure of how clean your water is, is how much of its fish you can safely eat.

Crude oil shipments by rail increased by more than 80 percent, nationally, last year.

Most of it is coming from the Bakken oil fields of North Dakota. That crude is more flammable than other types of oil, and has been shown to catch fire and explode when trains derail.

More than 15 trains of Bakken oil move through some parts of the Northwest each week, en route to refineries and terminals in Washington and Oregon.

Burlington Northern Santa Fe Railway transports the majority of that oil.

The company regularly touts its commitment to safety.

But an EarthFix investigation reveals some troubling patterns in the way BNSF Railway deals with whistleblowers – particularly those who voice concerns about safety.

The Obama administration’s new rules to cut CO2 emissions sparked some interesting conversation in Seattle this week. At a conference held downtown, leaders in the energy sector gathered to talk about the future of coal in the West. Ashley Ahearn reports for EarthFix.

The Oso Landslide highlighted a challenge that is not new to the Northwest: how to keep population growth out of risky areas.

Snohomish County has to make room for up to 220,000 new people by the year 2035, according to state requirements. And like many other parts of the Northwest, there are a lot of places where landslides pose a threat to current, and future, homeowners.

In part two of our series from EarthFix, Ashley Ahearn takes a look at development pressure and landslide risk in Snohomish County.

The Northwest is a region prone to landslides.

That, of course, is on many people’s minds as the town of Oso, Washington recovers from the tragic slide that happened there this past weekend.

There is a lot of scientific data and maps showing where landslides have occurred in the past.

The question is whether or not it’s getting used.

Authorities have confirmed that the landslide on the Stillaguamish River in Snohomish County has killed 8 people and destroyed up to 30 homes.

KUOW's Ashley Ahearn turned to Dave Montgomery to find out what caused the slide. Montgomery is a geologist at the University of Washington.

More oil is moving through Washington state from the Bakken oil fields of North Dakota. That has many concerned about oil train safety. The oil has proven extremely flammable, causing several explosions in North America.

State legislators on both sides of the aisle introduced bills to address the concerns.

But the session ended last week without a compromise.

Steelhead in Puget Sound have been listed as “threatened” under the Endangered Species Act since 2007. Millions of dollars have been spent improving the habitat of this iconic fish, but the population isn’t increasing. In fact, a lot of the fish aren’t even making it out of Puget Sound and scientists can’t pinpoint why.
