I used to think senior versus junior water rights was mostly a technicality — something lawyers worried about, not buyers. I was dead wrong, and it almost cost me access to the one creek that made a property worth owning.
I was looking at 80 acres in the Bitterroot drainage. Great riparian corridor, healthy willows, decent trout habitat. The listing showed water rights. What nobody volunteered — and what I didn't press hard enough on — was that the priority date on those rights was 1987. Every upstream neighbor with a pre-1960 date could legally dry that creek to nothing in a low water year, and in recent summers, they have.
I walked away, but barely. The next buyer didn't.
In the arid West, a water right without a strong priority date isn't really a water right. It's a maybe. Brokers treat all decreed rights like they're equivalent, and they are not.
Anybody else bought into a basin where junior status made your rights essentially worthless in practice?
