Priority Date Explained: Why It Matters More Than the Age of the Trees

An explanation of water right priority dates and why they matter more to orchard and vineyard buyers than how old the trees or vines are.

People shopping for orchard or vineyard property in the Yakima Valley often ask about the age of the trees or vines first. That is a reasonable question, but it is usually not the most important one. The priority date attached to a property's water right tells you far more about its long term reliability than the age of anything growing on it.

A priority date establishes when a water right was first recognized, and in a system where water is shared among many users, older priority dates generally get served first in times of shortage. A property with a senior priority date has a different level of security than one with a junior date, even if the two parcels sit next to each other and look identical from the road.

This is part of why June Solis asks about the district and the priority date before anything else when looking at a property. The house, the trees, the vines, all of that can be replaced or replanted over time. The priority date cannot be recreated. It is fixed to the history of that specific water right.

For a buyer, understanding the priority date means understanding how the property is likely to perform in years when water is limited. For a seller, having that information documented and ready to share builds confidence with buyers who know enough to ask.

A block of young vines with a strong priority date and a well documented water right can be a more secure purchase than an established orchard with a shakier one. The trees tell you what the land has been. The priority date tells you what the land can count on.
