OREGON FLOW REPORT

Last Updated: December 19, 2025

Oregon's river conditions display a complex and varied picture across the state, with some areas experiencing significant streamflow deviations from the norm. The Umatilla River, particularly above Meacham Creek, has seen a remarkable rise in streamflow, reaching 1050 cubic feet per second (cfs) with an astonishing 514.04% increase in the last 24 hours and an overall 460.03% of the typical flow, indicating potential flooding concerns near Pendleton. Contrastingly, the Owyhee River near Rome reports flows at only 156 cfs, marking a decrease by 9.3 cfs in the past day and standing at a worrying -18.41% of the expected flow, hinting at a flow drought in that region. This could impact river activities, including fishing and rafting, which are popular on this river known for its challenging whitewater sections.

Cities like Grants Pass and Medford near the Rogue River should remain vigilant as streamflow readings near McLeod show a lower than normal flow, with only 1920 cfs, down 15.04 from the last day and -38.68% of the average. Meanwhile, the Willamette River, a significant water body running through important cities like Portland, Salem, and Corvallis, shows a mixed state with the flow at Salem reaching 47200 cfs, which is 58.38% of normal, while at Corvallis it stands at 10700 cfs, falling short at -16.96% of the average. Recreational users such as kayakers and whitewater enthusiasts should take note of these variations, as they could influence the conditions of popular trails like those on the Clackamas and McKenzie Rivers, which are currently flowing at 60400 cfs and 13300 cfs near Estacada and Hayden Bridge, respectively, indicating exceptionally high flows and potential for exhilarating but also hazardous conditions.

       



Oregon's surface flows are impacted by its varied hydrology and climate characteristics. Major rivers and tributaries include the Columbia, Snake, and Willamette. Reservoirs and dams, such as the Bonneville Dam and the Dalles Dam, have been constructed along these waterways to provide hydroelectric power and irrigation. Snowpack is a crucial factor in Oregon's water supply, with the majority of the state's precipitation occurring in the winter months. In recent years, lower than average snowpack levels have led to drought conditions and water shortages. The Klamath Basin has been a focal point in the state's water management, with disputes arising between farmers, tribes, and environmental advocates over water allocation. Overall, Oregon's water resources are complex and often contentious, requiring careful management and planning.


       

Winter Storm Warnings

December 19 2025

Residents across Oregon are urged to exercise caution as multiple flood warnings are in effect throughout the state. The Sandy River near Bull Run is experiencing moderate to major flooding, with significant bank erosion and debris expected, especially near Troutdale. The Alsea River near Tidewater and the Siuslaw River near Mapleton are also forecasting flooding, with the latter affecting numerous rural roads and structures in low areas. Additionally, a winter storm is impacting the Northern Blue Mountains and the East Slopes of the Oregon Cascades, with heavy snowfall expected to create hazardous travel conditions. Cities like McMinnville and areas in Deschutes County face imminent flooding risks. Communities are advised to stay alert, follow local emergency instructions, and avoid traveling through affected regions.
