The Washington Department of Ecology has filed a lawsuit on behalf of the Lummi and Nooksack tribes, demanding up to a 50% increase in total surface and groundwater allocation for the tribes. This has led to over 35,000 subpoenas being sent to private well owners in Whatcom and northern Skagit counties, threatening to drastically reduce their long-established water rights from 5,000 gallons per day to just 350 gallons.

Why it matters

The lawsuit is seen as an attempt by the Department of Ecology to use tribal water rights claims as a legal shield to ultimately gain control over all water resources in the state, transferring effective ownership to sovereign tribal governments at the expense of Washington citizens. This raises concerns over property rights, due process, and the state's role in adjudicating federal tribal water claims against its own citizens.

The details

The Department of Ecology filed the lawsuit in Whatcom County Superior Court, Case 24-2-80000-37, on behalf of the Lummi and Nooksack tribes. The tribes are demanding a 50% increase in their total surface and groundwater allocation. The lawsuit has led to over 35,000 subpoenas being sent to private well owners, threatening to force metering of wells, drastic reductions in long-established water rights, mandatory individual court appearances, and new fees for well owners and water associations.

  • The Department of Ecology filed the lawsuit in February 2026.

What’s next

The Property Owners Well Water Rights Alliance (POWWRA) is seeking to secure expert federal counsel, such as Lawrence Kogan, to fight the lawsuit on jurisdictional, due-process, and constitutional grounds. They are also calling on the state legislature to rein in the Department of Ecology's efforts to centralize control over water resources.

The takeaway

This case highlights the growing tension between tribal water rights claims, private property rights, and the role of state agencies in adjudicating these disputes. It raises concerns about the potential for the Department of Ecology to use tribal lawsuits as a means to expand its control over all water resources in Washington, potentially at the expense of long-held private well rights.
