Attention Nooksack Basin Residents and Business Owners: Urgent Water Rights Alert for Nooksack Watershed Residents

If you depend on water from wells, streams, or lakes within the Nooksack watershed, it’s vital to engage in the ongoing water rights adjudication process. Initiated by the Washington State Department of Ecology (DOE) and filed in Whatcom County Superior Court, this legal action under RCW 90.03.140 and RCW 90.44.220 will significantly affect water usage across the Nooksack River system.

What is Water Adjudication?

Water adjudication is not merely a legal formality; it is a critical process that will establish the hierarchy of water rights throughout our watershed. As pressures mount from increased population demands, environmental shifts, and the sacred tribal rights to fish, water adjudication becomes a battleground where every drop counts. This process will ensure that water use is regulated fairly and sustainably, preserving our most vital resource for future generations.

What is a Watershed?

In Washington State, the landscape is organized into 62 major watersheds, also known as Water Resource Inventory Areas (WRIAs). These geographic areas are defined by the natural drainage patterns of the region's precipitation. Each WRIA collects rain and snowmelt, channeling these waters through a network of smaller subbasins into streams, tributaries, and rivers. These waterways eventually converge and typically empty into larger bodies of water such as the Pacific Ocean or the Columbia River. This system plays a crucial role in the hydrological cycle, supporting diverse ecosystems and human communities across the state.

Upcoming Key Dates and Events:

1. April 2025: Virtual Workshops (Hosted by Whatcom County Public Works & Aspect Consulting) are starting on April 22nd, providing crucial guidance for residential well users on preparing their court claim forms. Each workshop will last one hour and cover the adjudication process, demonstrate useful tools, and include a Q&A session. Registration is required. For those unable to attend, recordings of the events will be made available on the official adjudication page.
2. May 2025: Virtual workshops will continue through May with 8 total. In-person events are also scheduled to offer additional support and resources. Details and exact dates will be updated here.

Who Needs To File?

- Do you use water from a private well, stream, or lake in WRIA 1?

- Do you live outside a public water system?

- Did you receive a legal summons or certified mail?

If you answered yes to any of these questions, you must file a court claim form.

Immediate Action Required:

The adjudication process kicked off with a preliminary hearing on June 26, 2024. If you use water in the Nooksack watershed, you should have already received a legal summons instructing you on how to file a claim for your water rights. Failure to respond could result in losing your water access. This process involves around 30,000 stakeholders, including individual users, local governments, and tribal entities. Compliance with existing regulations for permit-exempt wells is crucial to maintain your rights.

Why This Matters:

This adjudication process will establish the legal allocation of water rights across the Nooksack River system, impacting approximately 30,000 stakeholders, including local governments, tribal entities, and individual users. This adjudication will profoundly impact various sectors, especially the roughly 1,500 farms relying on this water for irrigation, as well as local homeowners and businesses. Balancing water distribution is essential for sustaining agriculture and supporting the community's future water needs.

Received Your Court Claim Form? What To Do Next:

1. Understand Your Role: You’ve been identified as someone who uses water directly from sources like wells, streams, or lakes in the Water Resources Inventory Area (WRIA) 1. It’s crucial to file a court claim form to legally secure your water use rights.
2. Review Your Packet: You should have received a packet containing important documents including a summons, instructions, a court claim form, and more. These documents are essential for completing your claim.

   • The names of all property owners where the water is used (all must sign the form).
   • Estimate the time needed; it might take 30 minutes to two hours to complete.
4. Utilize Resources:
   • Use the water use calculators provided by Whatcom County Public Works to estimate your water usage.
   • Check the WRIA 1 map tool to see if you have water rights documents already on file.
   • Retrieve your well report for details like well depth and tag number if your well is registered.
5. File Your Form:
   • Online: The easiest method is online through Whatcom County Superior Court’s Guide and File system, where you can either submit electronically or download and print a filled form.
   • In-Person: Deliver a signed original form to Whatcom County Superior Court at the address provided.
