The Corps of Engineers' Northwestern Division led a regional exercise June 14-16 to prepare its teams of emergency planners, operators, and engineers for the possibility of a severe earthquake from the Cascadia Subduction Zone.

That sounds fishy: demonized trash fish finally gets some respect

Leaves are changing, the weather is cooling and getting wetter, and Fred Meyer is stocking its shelves with Christmas decorations, which means it’s October. Instead of skipping ahead to winter holidays, let’s fall back and celebrate autumn and Halloween by highlighting a fish that has been demonized in the past, partly for its looks, and partly for our past perceptions of it as a blood-sucking, bottom-feeding trash fish*: the Pacific lamprey.

Mother Nature can be comforting but has scolded (scalded) us this year

Mother Nature can be comforting and calm but this year it seems like she used our first, middle and last name as she scolded (or scalded) us … “Pacific North [emphasis added] West, what in the world were you thinking?!” … for punching our hypothetical little sister (California). Our punishment has been drought, record-breaking temperatures, wildfires and extremely dry conditions throughout the region. Even though the early part of this summer was a scorching hot nightmare, north western Oregon is fortunate to have a consistent flow of water – thanks to the U.S. Army Corps of Engineers’ system of dams and reservoirs in the Willamette Valley.

That sounds fishy: fish ladders at high-head dams impractical, largely unneeded

Humans. What other sentient being designs a tool requiring hands and feet and expects animals without limbs to use it? Alas, the answer is humans. Humans created a ladder for fish, which is quite effective in certain situations – but isn’t a blanket solution to every fish passage problem. And while most humans would agree that ladders can be useful for climbing short distances, perhaps 20-50 feet– another tool – like an elevator or truck – may be a better option to climb hundreds of feet. Otherwise, there would need to be more infrastructure to support that ladder, or perhaps it would need to be a staircase at that point. This is similar for fish when moving them up and downstream.
