      Hi Grady!
      Another awesome and inspired video, well done.
      I say this with the greatest respect for you and tremendous love for your documentary style: Please, please stop saying 'impact' and 'impacts' when you mean influence, effect, result etc. With such a rich source of descriptive words in English, it's insulting to hear an engineer (engineering communicator, no less!) sound like a marketing executive!
      All the best,
      from an Australian fan!

      @Based_transition_Clocker The sort of person who finds a video like this interesting is just someone who is fascinated by curiosities. On the other hand, homeless are starving on the street while taxpayer dollars go to getting lamprey where they need to go.
      While the video overall was cute, it never went into the economics of why it's actually more cost-effective this way. So bears upstream won't go extinct - how much tourism revenue are they bringing to Washington, anyway? What's the ecosystem look like? Who are the actuaries that determined that the ramifications of screwing over the salmon outweigh millions on making a fish bible?
      Real intelligence considers more than just a fascinating curiosity at hand, but broader implications. Without an actual discussion here as to what those implications are and what work was done to consider them, this is just a puff piece for the location and a feel good place for the humanity behind it. You don't need to be a genius to think dams are interesting, but you need to be pretty arrogant to consider this kind of puff piece to be an intellectual pursuit.

    • @Max-hn5fs
      @Max-hn5fs 5 місяців тому +3

      @@far2ez One very low detailed economic reason for all this: If salmon can't get upstream, they can't reproduce. If they can't reproduce the population will go down. Fishers that will catch salmon will have a harder time and most likely get restricted in how much salmon they are allowed to catch to not make them extinct. And thus salmon will get more expensive.

    I am so thrilled to have found this video. Several years ago I worked on a project relating to the Ardnacrusha power station on the River Shannon in Ireland. Turns out that the fish pass was only built 60 years after the hydroelectric station began its work - with the result that most of the salmon and eels that used to travel far upstream to reproduce had fallen victim to the impossibility of getting over the hurdle.
    With the remedial work a hatchery was installed that eventually helped restock rivers in Ireland and abroad, e.g. the Rhine.
    That hatchery attracted me like a magnet and I followed the complete cycle - and fell in love with the hatchlings.
    Knowing that the whole business can be managed so much better now and the negative impact on the fishes reduced considerably gives me great joy.

    As the FERC inspector of fish passage facilities at non federal dams here in the northeast US (retired), it was gratifying to watch the Corps efforts in trying to balance energy generation and natural resources at their power facilities. We do not have the size and scale of those facilities here so the fish passage designs are much smaller but no less important and much more varied. If you're a hydro guy you know its the only real renewable power resource. It's too bad the Klamath River projects could not be retrofitted similarly and instead just removed.

    Grady, last time I toured the Bonneville hydroelectric dam (very close to this one in the video) there were ten enormous turbines in the main room, and not a single one of them was generating electricity at the time despite the roaring Columbia River outside. The tour guide said that's often/typically the case, explained as "economics," though I can't understand how free clean energy could be any more economical. I wasn't about to lock horns with the guy during a tour, but it would be great if you could do a deep-dive on why turbines are typically/often just left off. Thanks!

    Granted I need to read actual papers and whatnot, and of course the construction “cost” notwithstanding it seems like they can somewhat work. The main bits i am unsure on especially are the non-Salmon (or other “big name” wildlife), so eel ladders being mentioned has me excited.
    Another Bit: Controlled Sediment Release was mentioned a while back on the news, i need to read up on it, but basically allowed a *little* flooding to keep the sediment flowing / make the river *slightly* more natural. Granted you may have mentioned this in the video, if so ill edit this out lol, enough rambling back to watching!

      The effect of lost sediment is a really good point! The Columbia River estuary has been heavily degraded from loss of new sediment and changes in flow regime. It equates to an approximately 70% loss of estuary habitat because these dams alter the system so drastically.
      Also, I'm glad you think about non-salmonid passage. Fish ladders are selective and do not help less charismatic (i.e. forgotten) species that they were never designed for....

      "SEVIGNY: Sandbars were once common in the canyon, built by the sand, washed down in annual spring and summer floods. Then in the 1960s, the dam was built, and beaches started to vanish. Chapman says that's a problem not just for river runners but also native plants and animals.
      CHAPMAN: There's kind of some calm areas. And the back of the eddy is kind of tucked in behind the sandbars, called backwaters or return channels, that are a critical habitat for a bunch of the native aquatic species.
      SEVIGNY: That includes four endangered native fish. In the '90s, Federal river managers started to experiment with artificial floods, ramping up the water released from the dam over several days. These floods are small compared to what used to come down the river but four or five times higher than typical dam releases. It worked."
