Water Rights, Drought Zones, and Securing Supply
Owning land does not mean owning the water under it or beside it. That surprises people from outside the American West, where a century of law has separated the two so thoroughly that water rights trade as their own asset class. When you site a large water-consuming facility, you are stepping into a legal system built to ration scarcity among users who have been fighting over it since before your company existed. The operators who win are the ones who treat water procurement with the same seriousness as power procurement: early, legally sophisticated, and with a clear picture of who else has a claim on the same drops. Do this badly and you will discover, after you have poured the foundation, that your water is spoken for.

Under the prior appropriation doctrine common in the western United States, what determines whose water claim is honored first during a shortage?
Show the answer
Seniority of the claim, captured by the phrase 'first in time, first in right.' The user with the oldest (most senior) water right gets their full allocation before any junior right holder receives water at all. A newcomer's right is junior and is curtailed first in a drought, regardless of how much they paid for the land.
