In the West, a ranch is often worth what runs through it. A plain-English look at how rights are measured and why they matter.
In much of the West, water follows a simple and unforgiving rule: first in time, first in right. The earliest recorded use gets its full share before a newer right gets a drop. In a dry summer, that priority date is the difference between green meadows and dust.
That is why two ranches with the same river frontage can be worth very different money. The one with a senior, decreed right and the infrastructure to move that water is a working asset. The one with a junior right and a pretty view is a gamble on the weather.
When you evaluate a property, ask for the water court decree, the priority dates, and a candid account of how the right has been used and maintained. Water is the part of a Western ranch that cannot be built, borrowed, or bought later. It is the value, hiding in plain sight.
