After months of winter steelheading, and with spring a few days away, wet-wading and sunshine are starting to sound pretty appealing. But warmer temperatures also bring some complications for summer steelhead in the Columbia basin. Tributaries like Herman Creek, Eagle Creek, Little White Salmon, and the Deschutes River deliver cold water to the Columbia even when air temps climb. Summer …
Science Friday: Why do juvenile steelhead move at the onset of winter?
By John McMillan We are going old school today, Science Friday style. No, we’re not talking about shooting ourselves with a tranquilizer gun, going streaking, or starting a fraternity to compensate for a mid-life crisis. We’ll leave that to Will Ferrell. But we are going back in time, to 1971. Today we revisit one of the foundational pieces of …
Science Friday: Behavioral Thermoregulation
Most steelhead anglers know that the family of fishes called salmonidae (trout, char, salmon and whitefish) are highly sensitive to water temperature and quality. These fishes require cold, clean water to thrive. But what happens to them when water temps become unfavorable? As you might expect, they seek out places in the river that regain cool water — now often …
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 …
