WASHINGTON FLOW REPORT

Last Updated: December 28, 2025

Washington state's river enthusiasts should note several key streamflow trends and noteworthy changes based on recent data. For example, the Spokane River at Spokane showcases a substantial 211.74% of its normal streamflow, which may interest whitewater aficionados, while the Little Spokane River near Dartford is flowing at a mere 18.04% of its norm, potentially affecting leisure activities and local ecosystems. Additionally, the Columbia River at the International Boundary reports a significant streamflow of 118,000 cubic feet per second (cfs), though it's only at 29.01% of its normal rate, indicating potential issues with water volume for downstream users.

In contrast, the Skagit River at Marblemount is flowing at 85.13% of its typical streamflow, with a recent increase of 6.19% in the last 24 hours, suggesting a stable and healthy watershed that could support various recreational activities. Cities like Renton, along the Cedar River, may experience increased water-related recreation potential, with the river flowing at 56.62% of normal, yet it's essential to remain vigilant for rapid changes that could indicate flooding. Areas near major whitewater trails, such as those around the Columbia or Spokane rivers, should stay informed of changes like the Spokane's 23.84-foot gage height, which could signal thrilling conditions for experienced paddlers but also pose risks. Therefore, river users must stay updated with current streamflow conditions and be prepared for variability that could impact safety and access to waterways.
