In mid-December 2025, heavy rains and rising rivers across Northwest Washington brought widespread flooding that deeply impacted communities in Whatcom County — and for the Lummi Nation, the impacts were severe enough to prompt a formal state of emergency declaration.
A Community Surrounded by Water
The Lummi Reservation, a low-lying area shaped by its proximity to the Nooksack River and the Salish Sea, has long dealt with flooding. However, the latest atmospheric river-driven storms pushed water to dangerous levels, cutting off most access points and isolating parts of the reservation.
According to tribal leadership, only one of four main routes into Lummi remained passable at the height of the flooding — a reality that underscores just how vulnerable transportation and emergency access have become during severe weather events.
What Prompted the Emergency Declaration?
On December 12, 2025, the Lummi Indian Business Council declared a state of emergency. Tribal Chair Tony Hillaire explained that access challenges, rapidly rising water, and infrastructure risks — especially around local levees — created conditions dangerous to community safety.
In a community of roughly 6,000 residents, the loss of multiple access routes elevates risk for medical emergencies and slows response times — a core reason why tribal leaders took the emergency step.
Levees, Infrastructure, and Ongoing Concerns
One focus of emergency management has been monitoring the Slater Road levee, a critical flood control structure that held during this event, even as waters surrounded homes and filled roadways. Officials met with the U.S. Army Corps of Engineers to assess conditions and watch for potential breaches.
That vigilance stems from past experience: in the flooding of late 2021, a breach of the same levee forced the community to rely on boats for deliveries and medical access.
Regional Flooding, Tribal and State Response
The Lummi Nation wasn’t alone. Other tribes in Western Washington — including the Nooksack Indian Tribe and Snoqualmie Tribe — also declared emergencies due to widespread flooding triggered by record rainfall and atmospheric rivers sweeping across the region.
Meanwhile, Whatcom County and state officials transitioned from immediate rescue efforts to recovery and damage assessment, opening shelters and coordinating with tribal partners and emergency response teams.
The Bigger Picture
Flooding along the Nooksack River and in surrounding areas continues to serve as a reminder of the intersection between climate-driven weather extremes and community resilience needs. For Lummi Nation residents — where “hundred-year floods” seem to occur with alarming frequency — infrastructure improvements, long-term planning, and coordinated emergency preparedness are now more urgent than ever.
