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 …
Steelhead biology for anglers
One thing you will notice about anglers who have spent a lot of time on the water, and I mean a potentially unhealthy amount of time on the water, is they catch fish. This can be frustrating to new anglers who are just learning to steelhead fish and spend many fishless days casting. There is no substitute for time …
Time to rethink what you thought you knew about steelhead
John McMillan I bet we all think we know what a steelhead is: a rainbow trout that goes to the ocean and returns to spawn in freshwater. I agree. But, new research indicates that the definition may not be so simple. Jason Hall, a researcher with NOAA in Seattle at the Montlake Lab (Northwest Fisheries Science …
Asotin Creek – WDFW update
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
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
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 …
Steelhead in Orlando ICAST/IFTD report
Each year in Orlando the entire fishing industry gets together for their trade show, ICAST/IFTD. It’s the place where everyone who makes a living off the tug on the end of a hook gathers to see what is new, take orders from dealers and learn about trends in the industry, including conservation issues. With so many industry professionals present the …
Rivers of Resilience – Asotin Creek
Asotin Creek is a tributary that drains into the Snake River near the town of Asotin in eastern Washington. With a drainage area of 250 square miles, Asotin Creek is slightly larger than the Wind River, but also much smaller than the Yakima River watershed. Like the Yakima, the basin is located in a semi-arid environment. Most of the watershed …
Rivers of Resilience – Wind
The Wind River, a tributary to the Columbia River just above Bonneville Dam, is, at only 224 square miles, a substantially smaller drainage than the Yakima. It receives more precipitation and thus is dominated by forests and industrial timberlands. The Wind River has had some habitat restoration but nowhere near the extent of the Yakima, but that is also because …
Rivers of Resilience – Yakima
It can be hard to maintain faith in the steelhead world. As noted in the recent article by Bill Herzog, it seems like we are losing wild summer runs faster than we can recover them. I would hedge that many, if not most, anglers feel the same. Steelhead are not disappearing for lack of effort though. Frankly, it’s amazing …
