Angler Science opportunities in Washington

In Science Friday, Washington by Nick Chambers

It is that time of year again where we all get the opportunity to become citizen scientists on the weekend (basically, we get to have fun playing in streams).   I am happy to inform you all that – like last year – TU and Wild Steelheaders United will be conducting steelhead redd surveys in Washington’s Hoh River and sharing …

Science Friday: Tillamook Bay Steelhead

In Oregon, Science Friday by Nick Chambers

Do you ever wonder what we might be missing nowadays in terms of steelhead life histories? Although we can’t go back in time to answer this question, we can look at historic data — in this case from Oregon’s Tillamook Bay. By the 1940’s Oregon’s Tillamook Bay was a patchwork of homesteads and farms, appearing more like the present day …

Juvenile steelhead doing what it takes to become a smolt: You grow in summer, I’ll grow in winter

In Oregon, Science Friday, Steelhead Files, Washington by Nick Chambers

Another Friday, another blog post on the science of steelhead. We love this day of the week! Our topic this week is the growth of juvenile steelhead.  Did you know that the growth rate of steelhead can vary depending on the season of the year?  This variation in growth rate can be considerable. There are a number of reasons that …

Asotin Creek – WDFW update

In Idaho, Science Friday, Steelhead Files, Washington by steelheaders

By Ethan Crawford, Fisheries Biologist – WDFW Asotin Creek Project An earlier blog post described the great resiliency of wild steelhead in Asotin Creek and noted that this resiliency is in part due to a combination of a variety factors: improved habitat quality, increased spill at hydroelectric facilities, good ocean conditions, and a great reduction in hatchery origin steelhead spawners, …

Life history diversity: dispersing risk

In California, Science Friday, Steelhead Files by steelheaders

By Brian Hodge Just as investors diversify their portfolio of assets to minimize financial loss, fisheries managers may diversify their portfolio of conservation strategies to minimize species loss. Another fishy analog for the “portfolio effect” comes from the steelhead—it reduces risk of extinction by displaying a diverse array of life histories, or pathways from hatch to spawn. My colleagues and …

The advantage of avalanches

In Idaho, Science Friday, Steelhead Files by Shauna Sherard

  Here in this timbered, steep, up and down country of Idaho, the forces at work are not merely wind and water. Here, the tumble of rocks and cracking of large trees has been important to shaping river habitat for centuries. Avalanches are not just territory for the backcountry skier. They’re good for steelhead too. Think of them like door-to-river …
