i thought hydropower screws up the ecosystem of rivers pretty badly. LIke fish unable to spawn and all that.

I present you the most amazing solution to this: https://www.youtube.com/watch?v=2z3ZyGlqUkA

Not to mention that the dams in Washington state do account for spawning/migration and slow down flows at certain points of the year.

These have to be manned? Like 24/7 or...how much human labor is involved here? What % of salmon make it into human hands and through these tubes?

Earlier attempts at fish ladders saw rates as low as like 3% for certain species of fish, per ladder/dam. Even if 50% of salmon got up them, if they have to pass 5 of them on the way to the spawning ground that meant 97% of salmon wouldn't make to the spawning grounds.
