Water allocation in the American West has been a mess ever since the beginning, when Prior Appropriation was decided as the way to claim water rights. Essentially, the first person to put a claim of water into "beneficial use" gets those rights.

This is why you see California with such a large share of the Colorado River's water rights, even though it "touches" the river the least: they were the earliest fast-growing state to "use" that water. And that's why you see so many water-hungry crops being grown in the West--the owners have the rights already, and to them, if they don't use it, they'll lose it.

So any agreement here needs to make a compromise between states, the federal government, prior settled law, and owners with effectively "free" water that don't want it taken away from them.

It's a complicated issue, but one step would be to force private owners of water rights to list their rights on an open market (right now some owners of water rights, like the Imperial Irrigation District can choose to never sell them). At least that way you can start the conversation somewhere.

(In fact, John Wesley Powell, namesake of Lake Powell, argued strongly against "prior appropriation" before the area was even settled, and instead argued against a collective approach to the limited and volatile amount of freshwater. He did not succeed.)

You don't need to force them, they've done it for decades to the extent it is allowed. I've owned titled water rights in Nevada. They are worth something but not nearly as much as many people likely assume.

Nevada has additional complications due to the structure of the aquifers. It is difficult/impossible to move water from where it is to where it may be needed.

Guess - you're referring not to the aquifers themselves, but to the shape of the watersheds. Especially to the "water doesn't naturally flow along roller coaster tracks" topography of the https://en.wikipedia.org/wiki/Basin_and_Range_Province

You do not even need to force water rights owners to list their rights on the open market. They already want to, it is just illegal for them to sell their water rights (separate from their land) to entitys with more productive uses of the water.

That's not a solution, either. See William Mulholland buying up the water rights in the Owens Valley to feed Los Angles, thus turning Owens Lake into toxic dust that is costing $1 billion and counting to manage. Mulholland is long dead, and we're just getting started paying for that.

Water rights in the West are hard, and we've known that since John Wesley Powell was in charge, as a nearby commenter explained. The Colorado was divided up during an unusually wet year a long time ago, and rising demand and falling supply have only made things worse ever since.
