Last Friday, Washington’s Fish and Wildlife Commission (FWC) voted 5-4 to reform its Columbia River Basin Salmon Management Policy (C-3620), which guides salmon management in the Columbia and Snake Rivers.
Science Friday: The risks and rewards of barging steelhead smolts
Sea-run Snake River fish species must pass through eight dams, four in the Snake and four in the Columbia. Barging some of them past these dams helps them avoid most of the harmful impacts associated with the hydropower system.
Ya Gotta Believe!!
By Bill Herzog Back in 1969, the New York Mets made baseball history. The “Amazin’ Mets,” as they came to be known, a team that had been dropped in the toilet like a three day old dead goldfish by most baseball experts, came from nowhere to shock the country and win the World Series that year. The Mets …
A stream with two stories — but only because it goes dry in summer
Most people think of the Pacific Northwest as a region of dense coniferous rainforest and myriad gushing rivers that drain mountain ranges influenced by a damp, cool coastal climate. And it is. But like every other part of the American West, this region also features one of the most important components of any watershed: intermittent streams. Intermittent streams are …
2017 – a Bad Year or Part of a Trend?
Ocean conditions are vitally important for wild steelhead runs — probably every steelhead angler knows this. But what does that phrase really mean? The ocean is a massive and incredibly complex system, and there are many factors out in the big blue that can influence steelhead in any given year. That is why it is so difficult to parse out …
Science Friday: More on summer and winter steelhead genetics
By John McMillan Two weeks ago we reviewed a study by Prince et al. that discovered a single gene differentiated steelhead which return immature (referred to as pre-mature in the study) to freshwater (i.e., summer steelhead) and those that return in a mature or relatively mature state (i.e., winter steelhead). Anglers have long known there is something inherently different about …
Science Friday: How summer steelhead are genetically different than winters
Many anglers over the years have no doubt wondered why some steelhead return to freshwater during the hottest and driest part of the year. The reasons why are both simple and complex. The most obvious difference between summer steelhead and their winter run brethren is that they enter freshwater streams in summer and fall, not winter. Duh. But that …
Science Friday: Warm water’s influence on the speed of upstream migrating steelhead
The dog days of summer are fully upon us. The predicted forecast for adult summer steelhead returning to the Columbia and Snake River basins is now, unfortunately, shaping up to be worse than expected (and it was already very low). However, it can be difficult to determine how accurate this forecast actually is because at this point in time the …
Stand Up For Clean Water
When anglers think of steelhead water, we tend to think of big, muscular rivers like the Skagit, Umpqua and Eel. We don’t usually think of tributary streams small enough to step across, or even that go dry at times. We should. Such streams are very important for steelhead, particularly for spawning and rearing. In California, for example, 64 percent of …
Science Friday: Hitch-Hiking Smolts
Last week we talked about the importance of spill for out-migrating kelts and smolts in the Columbia Basin. Increasing spill is only one method employed to enhance downstream survival of smolts. As early as the mid-1950s smolts were loaded onto barges and moved downstream past the dams through the lock system. While fisheries managers experimented with this tactic early on …
