Science Friday (PART ONE): Disappearing Steelhead – The Fate of Summer Steelhead Seeking Coldwater in the Columbia and Snake Rivers

In Science Friday by Gary Marston

In the Columbia and Snake rivers hydropower systems, many migrating summer steelhead overshoot their spawning streams, passing dams multiple times and increasing mortality rates, trying to find cold water refuge. We look at the ramifications on steelhead management for not properly accounting for these overshoot steelhead.

In Washington by Jonathan Stumpf

Beavers deliver conditions steelhead require in their spawning grounds — cold water, longer duration of wetted streambeds, and food-rich rearing habitat. Here’s why beavers are now part of the recovery toolbox for upper Columbia River steelhead.

It’s Time for Bold Action

In Snake River by Jonathan Stumpf

Rep. Mike Simpson (R-ID) has stepped up to lead toward a more optimistic future for the entire Snake River basin. Rep. Simpson laid out a proposal that would create new clean energy sources, build new infrastructure, and ensure the needs of local communities, irrigators and shippers are met. The proposal would also restore runs of healthy, harvestable Snake River salmon and steelhead by removing the lower four Snake River dams.

It’s time for the lower Snake River dams to go

“It is our collective opinion, based on overwhelming scientific evidence, that restoration of a free-flowing lower Snake River is essential to recovering wild Pacific salmon and steelhead in the basin.”

So reads a remarkable letter recently sent to the governors of Oregon, Washington, Idaho and Montana by 10 of the finest and most-respected salmon and steelhead scientists in the world.
