For some numbers:
One graph even has California's animal feed water usage so large it actually goes off the chart at 15.2 million acre-feet of water (it is distorted to make it fit as it notes). For some comparison, the blue water usage of animal feed is larger than all of almonds water usage of ~2 million acre-feet of water

EDIT 2:
Also worth noting is that per liter, dairy milk requires 628.2 L of freshwater vs almond milk requiring 371.46 L of freshwater. And if you use something like oat milk instead that gets you to 48.24 L
It undeniably does, but what would be interesting is a comparison of how much water is needed per liter of milk and various substitutes.

I suppose I should have guessed how much more resource-intensive dairy milk is just because it involves animals, but holy crap.
