Water Resources Adjudication manager Robin McPherson explains the Nooksack water right adjudication to a group of Whatcom County real estate brokers.

When it comes to water rights, buyers of homes and farmland can find out whether the current use appears to be legal under a permit-exemption or water right document. If the current use does not appear to be legally supported, it may not be able to continue in the future. Even where current use is legal, currently legal does not mean guaranteed forever – especially in times of drought or other water shortage.

We recommend that buyers carefully review available permit exemptions Focus on: The Groundwater Permit Exemption and Nooksack Watershed Water Availability to see whether water is available for a new use on that land. New residential development is generally allowed on individual wells up to 500 gpd indoors and with a 1/12-acre outdoor watering restriction.

In early 2025, Ecology will send certified mail via the United States Postal Service to all property owners in Water Resources Inventory Area 1 (WRIA 1) who are within the area of a recorded water right or outside a public water system service area. You will have a year or more to fill out the claim form and submit it to the court online, in person, or by mail.   If you miss the mailing or lose your claim form or instructions, extra forms will be available at Ecology offices that can be sent by mail or e-mail.

Buyers can find out whether an adjudication court claim has yet been filed on the property in question by looking at the Whatcom County Superior Court’s website. If no adjudication claim has yet been filed, they may be able to work with the seller to assure that an adjudication court claim will be filed, or that the buyer has necessary information to file a court claim themselves after purchase.

Buyers may also receive a disclosure form from sellers, Northwest Multiple Listing Service (NWMLS) Form 22X, The NWMLS has informed us that the purpose of this form is to alert buyers to the adjudication and, more importantly, to confirm that buyers are aware of the adjudication and that it is extremely important that buyer confirm whether seller has filed a claim form for water use on the property.
