Everyone has a different perspective about what it means for humanity to live harmoniously with all the other life we share the planet with. I think it’s fascinating how those ideas and endeavors trickle down through engineering into the real world.

Then, during the warmer months from May to September, we extend our hours to seven days a week, still from 9:00 am to 4:00 pm. No appointments are required; simply drop by at your convenience. In this video, Grady takes you on a journey to McNary Lock and Dam, nestled along the picturesque Columbia River in Umatilla, Oregon. While there, explore the intricate fish ladders, just one of the many marvels awaiting discovery. Don't forget, we also feature fish ladders at four other captivating projects along the Lower Snake River.

Aerial fish stocking does work, at least in certain circumstances. In Utah high elevation lakes that are inaccessible to trucks are routinely stocked from the air with very small trout. The fish are usually less than 2" in size and survival is well over 90%. Obviously a larger fish would just go splat, but the little ones almost float down like leaves.

Surprised you didn't include the Ballard Locks in Seattle while you were up in the PNW. Its an interesting example of a fish ladder that exists at the fresh/salt water boundary, and it mostly serves salmon descended from ones that were introduced by humans to replace runs we destroyed in the process of diverting rivers to construct the Ship Canal and locks. There's a publicly accessible viewing window near the top of the fish ladder if you are there during the migratory period, and the surrounding site hosts a small botanical gardens. Plus, the boat locks themselves are pretty interesting to anyone watching this channel!

@ars85202 2 ай бұрын
That's true and your PhD thesis sounds interesting, I have wondered myself about those impacts from the beginning of the video. I would add that, as a social scientist, one of the most important thing I can do is question whether or not our "human needs" are really needs for the working class and not just wants from the ruling class, and what are the real needs of the working class. One example is how the car and oil industries lobbied for car-dependent cities, creating an artificial need for their products at the cost of the working class. From the words of Chico Mendes, a Brazilian conservationist and climate activist, "ecology without class struggle is just gardening"

It’s fascinating that fish ladders are seen as essentially necessary for dams due to the fragmentation of their habitat, but the vast majority of roads through wild areas have no such consideration for wildlife. Habitat fragmentation from roads is an enormous problem, the book “Traffication” is all about how roads have destroyed natural habitats and created pockets of gene pools that don’t cross those roads.

I had to go rewatch the last week tonight, salmon cannon video after watching this. Amazing collaboration on that video.

Your content is such a refreshing change from the usual YT idiocy. Thanks for restoring my faith in the medium.

I remember being a kid and seeing the lamprey at this dam in oregon. Its cool to see a video about this +20 years later.

I can't imagine the number of hours of trial-and-error that went into these designs. That's a *lot* of work, right there. And I'm sure those designs are being refined even now, as the engineers and scientists learn more and more about these ecosystems.

The fact that you mentioned a dam that I see every time I go on a long drive makes me happy somehow

I've had the opportunity to visit the St Stephen fish lift in Berkeley County, South Carolina. It's impressive. The people that run that thing do a fantastic job and help greatly with conservation. Hundreds of thousands of striped bass and American shad swim through it each year and spawn. If any of you guys are ever in the area when the fish are running and ever get the chance to tour it I recommend it. They have viewing windows in the fish lift so you can see the fish swimming through it.

I was watching a documentary about the River Danube last night. Apparently the Iron Gates Dam has had a catastrophic effect on Beluga migration and so caviare production. It must be difficult designing a fish ladder for something the size of a beluga.

fun fact: with washington state, we love our hydroelectric dams (with understanding on my end) which also makes to understandable with fishway/ladders to be put in the designs of the state dams

We've just opened a fish sluice on the River Trent in England to bypass a large weir (I say large, I mean in English scales). I am going to see it next week!

In Sacramento, there’s a fish hatchery by the American River right before the Nimbus dam (a downstream dam off Folsom Lake). In the hatchery, they rebuilt the ladder with glass windows, so visitors can actually see the chinook salmons and steelheads. If you’re in the area, or just passing by to/from Lake Tahoe, go visit the Nimbus Fish hatchery.
