Had to look up the Colorado river because it wasn't big enough to even make the list, it's 37th in US alone. Wow, so many people rely on such a small river.

So much of the Colorado’s water is taken, this is highly influenced by where they measure.

The reasonable place to measure is somewhere near the river's mouth.

That would be tough for the Colorado; it’s my understanding that so much water gets taken out upstream that all that remains is a trickle in the Mexican desert that sometimes evaporates completely before reaching the sea.

What if all the water has been siphoned off by then? We could measure actual flow at the mouth, and theoretical "untouched" flow if no water was diverted or dammed

I thought the same thing.

I live in Vegas.

Not very comforting.

I expected the Colorado to be in the top 50.

Shocked it's not even in the list!
