Georgia and Atlanta have unsustainable growth which their natural resources can't support and are trying to pass off the externalities onto their neighbors. I am biased as a former resident of both Tennessee and Florida.
Politically, the Colorado is a different animal. Mexico is downstream and historically has just had to lump it when the river runs dry. Which it has as the US built dams. And today, it has to make do with just a remaining 5% of the historical wetlands where the Colorado flows into the Sea of Cortez.
Atlanta's artificial lakes/reservoirs are from a similar time, new ones aren't being made fast enough if at all, and the population continues to grow. Dealing with multiple jurisdictions (the region known as Atlanta encompasses the city of Atlanta, many other cities, and is spread across several counties) further complicates the issue when it comes to funding and determining responsibility. You could argue the state of GA should step in. However, there's a huge political chasm between the metro Atlanta area and most of the rest of the state (A "fuck those city slickers" attitude is very common in rural Georgia and the smaller cities, Atlantans aren't viewed as Georgians given how many are transplants). The water in the Atlanta region also needs to travel down river to many other areas (and other states) in order to sustain those regions.

I volunteered at an Audubon project trying to save the pacific salmon. The water rights issues break my brain. Farmers, timber, fisheries, native peoples, power, flood control, sanitation, household use, commerce, industry, etc.
I know nothing about this GA vs FL (vs TN) fight.
I've heard our legal context in The West is it's own crazy. For instance, IIRC, we have "use it or lose it", so Idaho potato farmers end up growing too many potatoes to avoid risking losing their water rights.
Insane, right?
I'd love to follow the thought leaders on water stuff. Like maybe create a market for water, so those Idaho farmers could sell / rent their water to others interests. I'd love for the Freedom Markets™ partisans to actually propose market designs and reforms that'd address these kinds of challenges. Similarly, I'd love for the treehuggers to get smart about using markets to more effectively and efficiently allocate scarce resources; a constructive alternative to the never-ending legal battles.
After carbon, water will certainly be one of our more pressing policy challenges, for a long while to come.
Please set me straight, point me in the right direction.
Also it's a fascinating read.
I'm always down for a good mega-engineering project.

In nominal prices that’s a 31% drop, but we also had ~34% inflation from 2005 to 2021. So relative to pipelines it’s a ~48% drop which is quite significant IMO.
My primary point is that piping water in bulk is mind-bogglingly cheap compared to what most people think. In fact, desalination is also mind-bogglingly cheap. The per-capita usage of water in the US is ~2800 m^3, so even if the US had no fresh water and had to get all of it from desalination that would only account for a $1400/person cost increase which is only 4.5% of the median income in the US. However, despite that, piping is even more insanely cheap to such a degree that it is still cheaper to ship it vast distances which is why we continue to deplete freshwater reserves even though desalination is actually an economically viable solution, it is just not market competitive yet.

There's only so much fresh water you can take from a natural source before you have an impact on wildlife order(s) of magnitude greater than what we've already done.
Most of California water goes to the sea. Of the remainder agriculture is the majority, but agriculture is also paying the most attention to water conservation overall. (though you personally might not water your lawn or golf, enough others do as to cancel out private residences)
18% of California irrigation water is used for alfalfa as livestock feed and is exported to other countries.

Dairy Products, Milk — $7.34 billion
Almonds — $6.09 billion
Grapes — $5.41 billion
Cattle and Calves — $3.06 billion
Strawberries — $2.22 billion
Pistachios — $1.94 billion
Lettuce — $1.82 billion
Walnuts — $1.29 billion
Floriculture — $1.22 billion
Tomatoes — $1.17 billion
Not seeing wheat or rice on this list. Sue me for saying this, but I don't think strawberries are critical to survival.Quick inference from the top hits:
almonds use 10% of the water to generate 12% of the revenue
compared to rice, almonds use 40% more water and generate x3 the dollar per acre-foot.

So while growing almonds in California is insane ecologically, it's pretty damn good economically.
