WASHINGTON FLOW REPORT

Last Updated: January 2, 2026

Washington State's streamflow conditions exhibit varied trends across different river systems, with some waterways experiencing below-normal flows indicative of potential drought conditions, while others are maintaining healthier volumes. Notably, the Spokane River at Spokane presents an elevated streamflow at 181.28% of normal, raising concerns for possible flooding in the surrounding areas, including the city of Spokane. Contrastingly, Hangman Creek at Spokane shows a significant drop in streamflow levels, currently at -58.5% below normal, which could signal flow drought conditions. The Columbia River at the International Boundary reports a streamflow of 93,100 cfs with a slight 0.11% increase in the last 24 hours, but remains low at 2.26% of the usual flow, which could affect large watersheds and potentially impact cities along its course. Additionally, the Methow River near Pateros exhibits a high streamflow change of 159.43% of normal, which could be a concern for recreational activities such as whitewater trails in the area.

Streamflows in major rivers such as the Pend Oreille River below Box Canyon and the Little Spokane River are also notable, with the former flowing at 71.64% of its normal rate with a current streamflow of 29,200 cfs and the latter showing significantly reduced streamflow rates, potentially impacting the river ecosystem and nearby communities. For water enthusiasts, the Wenatchee River at Monitor presents an 88.1% of normal flow that could affect water-based recreation. It is critical for river and whitewater enthusiasts to stay informed about these variable conditions, as they may affect accessibility, safety, and ecological health. Local authorities and recreationalists should closely monitor these waterways for any rapid changes that could indicate either escalation towards flooding or progression towards drought conditions, depending on the region within Washington State.
