TIL The Netherlands will be the 1st country to have a Fish Migration River!
Forget fish ladder, they’re building a whole river! Lol
Basically The Netherlands built the Afsluitdijk dam to protect against flooding from the North Sea, but it blocks off the migratory path for fish seeking freshwater to breed. The Fish Migration River is being built to correct that. It’s projected to be completed by the end of 2026 and will be both a nature reserve and UNESCO site.

I just learned about this after exploring the Fish Doorbell website (which is a really cool and cute visit actually, super recommend). It was mentioned in their Fishdoorbell news report:)
I hope the lock operator double-checks the footage instead of just trusting the Internet.
Nobody on the internet would misrepresent the truth
I'm sorry but Afsluitdijk sounds like they named it by banging on a keyboard.
It means closure dyke. If you want keyboard banging, go check the name of the vulcano in Iceland.

I was gonna say no way that's a real thing they can pronounce
Afsloutdike. We like to mix and match vowels here to create exciting new pronunciations!
Of course it's the Dutch
The Dutch national motto is "Fuck you nature watch this!"
Alfusaipond dam
Fish ladders are common things on dams nowadays. The only speciality I see here it's between sea and a lake.
Also, IIRC fish ladders don't actually work all that well, which is why fish cannons are the new "in" thing these days. (See also: https://99percentinvisible.org/episode/fish-cannon/ , https://www.whooshh.com/ -- yes, that's the real name/website of the company that makes the thing, LOL)
Seems like this project, "with a length of four kilometres and a spiral structure that simulates gently sloping water currents" (according to the "more reading" link), is a different approach to correcting the inadequacies of normal fish ladders.
I've only seen those used for salmon because those are large fish that make a concentrated seasonal migration in from the ocean. Fish ladders are fine for other species that are smaller and inhabit the river year round.
TIL "The Netherlands" is a country. I thought it was a region. Like how "North America" is 3 countries.
North America also includes a number of countries south of Mexico, Greenland, and some countries in the Carribean.
I think in the US (and english speaking parts of Canada) they have a weird conception that “North America” doesn’t include “Central America”.
But the rest of the world seems to agree that: North America = Central America + US, Canada, Mexico
and South America = Anything south of Panama on the American continent
I'm in the US, and that's certainly not how the US classifies things.
Some countries, like Spain, use a continent model with fewer continents, where there is no North America or South America, just one very large continent, "America".

I'd guess that they might not be familiar with where the division occurs.
You might be thinking of "Holland"? The Netherlands is sometimes informally referred to as "Holland", but that's also a region within the Netherlands:
The Low Countries is several countries, comprising The Netherlands, Belgium and Luxembourg. That might be what you were thinking of.
Are you dumb?
Yes.
In a few years whole of The Netherlands will be a fish migration sea.
