Seattle District Restores Flood Protection After Historic Pacific Northwest Flooding
US · Published Aug 26, 2026
In December 2025, a series of powerful atmospheric rivers brought unprecedented rainfall to the Pacific Northwest, causing catastrophic flooding, landslides, and significant infrastructure damage across Washington, Montana, and Idaho (DVIDS, 2026).
Western Washington experienced over 10 inches of rain in some areas, leading to rapid river rises and widespread flooding.

Impact & Risks

The December 2025 flooding severely impacted communities across Washington, Montana, and Idaho, damaging homes, agricultural lands, and critical infrastructure. The rapid rise of major rivers posed significant risks to public safety and property. The ongoing rehabilitation projects aim to restore flood protection systems to pre-flood conditions, reducing the risk of future flooding. Without these repairs, communities remain vulnerable to high-water events, which could lead to further infrastructure failures and economic losses. The restoration of levees, such as those in Skagit County, is crucial for protecting lives and property in flood-prone areas.
