You may have recently heard about the Water Adjudication happening in Whatcom County and wondered if it affects you as a homeowner. With so much information circulating, I wanted to share a quick overview and point you toward the right resources.

First, it’s important to know that I’m not able to provide legal advice, but I can help direct you to the official information available.

What Is Water Adjudication?

Water adjudication is a legal process being handled through the court system to determine water rights throughout the Nooksack watershed and surrounding areas in Whatcom County. The goal is to create a clear record of who uses water, how much they use, and where that water comes from.

This process includes water used from wells, streams, lakes, or other water sources within Water Resource Inventory Area 1 (WRIA 1), which covers much of Whatcom County.

Over time, the court will review submitted claims and determine the legal rights to use water and the priority of those rights.

Updated Deadline

Originally, many people believed the filing deadline was June 1, 2026. However, the court recently extended the deadline.

The new deadline to submit a claim is June 1, 2027.

The extension was granted in order to reduce confusion and allow more time for property owners to receive notice and complete the required paperwork.

Should Homeowners Be Concerned?

For most standard residential homeowners, this is not something to be afraid of.

The adjudication process is simply about documenting water use. Filing a claim does not automatically create a problem or trigger penalties. It is simply a way to record your water use in the court system.

Many homeowners will receive a form by certified mail if their property may be using water from a well or another non-municipal source.

If you receive one of these forms, it will ask basic questions about things like:

  • Where your water comes from
  • How the water is used (home, irrigation, livestock, etc.)
  • Approximately how much water is used

Helpful Tools

Whatcom County has created simple tools to help residents estimate their water usage, including a residential water calculator available on their website.

These tools are designed to help homeowners complete their forms more easily and understand their usage.

These sites provide instructions, timelines, and helpful tools if you receive a claim form.

Final Thoughts

While the process may sound intimidating at first, the important thing to remember is that the goal is simply to create a clear record of water use across the county.

With the deadline now extended to June 1, 2027, homeowners have time to learn about the process and access the resources available to help.

If you have questions about how water rights might impact a property you own or are considering purchasing, I’m always happy to help connect you with the right information.
