What's Happening & Why It Matters
Live in WRIA 1 and use a well, stream, or lake? The deadline to file your legal water rights claim has been extended to June 1, 2027.

What Is Adjudication?
A legal process to determine who has the right to use water, and in what amount. It protects existing users and ensures sustainable management.
What Is WRIA 1?
The Nooksack Basin — it collects water from rain and snow. Anyone using water from wells, lakes, or streams here is part of WRIA 1.
📢 Deadline Extended
The deadline for filing water rights claims in the Whatcom County WRIA 1 adjudication has been extended to June 1, 2027. Funding is secured and the adjudication process is continuing as planned.
Well Pump Maintenance & Your Water Rights
A properly functioning well pump demonstrates ongoing, beneficial use — a key factor in adjudication. Service records, pressure testing, and pump replacements create documentation that can support your claim if it's reviewed.
Create Records
Invoices and logs prove active, ongoing water use over time.
Support Your Claim
Documentation is critical if your claim is reviewed or questioned.
Prevent Gaps
Failures interrupt use — gaps that complicate proving consistency.

What Happens If You Don’t File a WRIA 1 Water Rights Claim?
If you fail to submit a claim by the extended deadline of June 1, 2027, the court may not recognize your water use in the final adjudication order. This could affect future water access, property transactions, or your ability to defend your historical use.
Common Myths vs. Facts
"My well is permit-exempt, so I don't need to file."
You do; even small household wells must be included in the adjudication process. “Permit-exempt” does not mean exempt from filing.
"I didn't get a summons, so I'm not involved."
You may still need to file if you use water in WRIA 1.
"It's just a government formality."
It's a legal process that could impact your right to water.
