WASHINGTON FLOW REPORT

Last Updated: December 23, 2025

Washington State's rivers exhibit a range of flow conditions as the seasons progress, with a few instances of notable streamflow changes that merit attention. The Spokane River at Spokane shows an exceptionally high flow at 20600 cfs, which is 240.65% of its normal, suggesting an increased risk of flooding that could impact the city and its whitewater enthusiasts. In contrast, Hangman Creek at Spokane has seen a significant drop, currently at a mere 12.28% of its normal flow, indicating potential drought conditions which may affect recreational activities as well as local ecosystems. Meanwhile, the mighty Columbia River at the International Boundary maintains a steady flow of 97600 cfs, though experiencing a small dip in the last 24 hours, remains essential for various water-related interests, from hydropower to fisheries.

Among the rivers typically popular for whitewater rafting, the Skykomish River near Gold Bar's flow has decreased to 7030 cfs, dropping to 21.17% of normal, which could affect the river's whitewater conditions. Significant decreases are also observed in the Nooksack River at Ferndale, flowing at 6810 cfs, or only 25.14% of its normal, potentially impacting local communities. Conversely, the Green River below Howard A Hanson Dam is flowing robustly at 4630 cfs, which is above the normal at 118.43%, offering robust conditions for whitewater and recreational activities, yet warranting caution for possible high-flow hazards. It is imperative for residents and visitors to stay updated on local advisories as these flow conditions can swiftly change, influencing safety and accessibility for river and outdoor enthusiasts across the state.

       



Washington state is characterized by a diverse hydrology that is heavily influenced by its climate and geological features. The state's major surface flows are the Columbia River, Snake River, Yakima River, and Spokane River. These rivers are fed by numerous tributaries and are regulated by large reservoirs such as the Grand Coulee Dam and the Bonneville Dam. The state's mountainous terrain and heavy snowfall create significant watershed systems that contribute to river flow, with the snowpack in the Cascade Range being a primary contributor. Climate patterns such as El Niño and La Niña can impact precipitation rates and snowpack levels, leading to drought or flooding events. Overall, the hydrology of Washington is a complex and dynamic system that is heavily influenced by both natural and human factors.


       

Winter Storm Warnings

December 23 2025

Residents in Washington State are advised to brace for a series of weather hazards. A Flood Warning is in effect for the Skokomish River at Potlatch in Mason County, causing widespread flooding with river stages already at 16.7 feet as of early Tuesday morning. The river is expected to recede Wednesday morning but not before inundating pastures and roads. Additionally, Wind Advisories have been issued across northwest and west central Washington, including the Foothills and Valleys of the North Cascades, Island County, and parts of Skagit, Snohomish, and Whatcom Counties, with gusts up to 55 mph potentially knocking down trees and causing power outages from Wednesday morning into the evening. Simultaneously, Winter Weather Advisories warn of snow accumulations between 2 and 5 inches in areas such as Mazama, Twisp, and Methow, which could severely impact travel, including the Wednesday morning commute. Citizens are urged to stay informed and exercise caution, particularly when traveling and in areas at risk of flooding or wind damage.
