  • 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.

  • That sounds fishy: twisting traps troll tributaries in the Willamette

    The bulky contraptions float listlessly downstream of three dams in Oregon’s Willamette Valley. The buoyant, metal devices hold large screws that the water flow turns. This twist of the screw – creating a creaking, rasping, scraping sound – generates enough hydraulics to keep small fish from escaping the slowly spinning, cone-shaped collectors – or, screw traps.
