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
