OREGON FLOW REPORT

Last Updated: December 29, 2025

Oregon's rivers are experiencing varied streamflow conditions across the state, presenting a mixed bag for river enthusiasts and locals. While the Owyhee River near Rome is flowing at a mere 10.92% of its normal rate, with a low streamflow of 282 cubic feet per second (cfs), the Rogue River at Raygold near Central Point is closer to its seasonal norm at 2660 cfs. A notable outlier is the Columbia River at The Dalles, which, despite a slight decrease in the last 24 hours, commands a massive flow of 132,000 cfs, although it is still only 10.54% of its normal flow indicating potential wider hydrological impacts. For whitewater adventurers, the Grande Ronde River at Troy offers promising conditions with a flow of 3320 cfs, while Shitike Creek near Warm Springs surged dramatically in the past 24 hours, a massive increase to 1480 cfs, which could signal potential rapid changes or flash flooding.

Focusing on specific areas, the Umatilla River is seeing significant decreases in streamflow, with the section at West Reservation Boundary near Pendleton dropping to 416 cfs, notably below normal. This contrasts with the John Day River at McDonald Ferry, which is flowing healthier at 1920 cfs, 84.33% of its normal flow. Meanwhile, the Snake River at Hells Canyon Dam is an area of concern with a massive 19200 cfs flow rate, yet only at 36.05% of its expected flow, indicating abnormal conditions that may affect ecosystems and local water supply. The Willamette River, a crucial watershed for the state, exhibits fluctuations, with the Portland section at 57600 cfs, slightly below its usual trend. Recreational users and residents in regions like Grants Pass on the Rogue River or those near the Nehalem and Siletz rivers should stay informed as streamflows are not at typical levels, which could impact water activities and local habitats. With the diversity of conditions and the potential for rapid changes, stakeholders should monitor local water data and be prepared for fluctuating river environments.

       



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 29 2025

Residents of Oregon, particularly those in valley areas west of the Cascades in Jackson, Josephine, and Douglas counties, as well as east of the Cascades in Klamath and Lake counties, should be aware of an Air Stagnation Advisory in effect until December 31 at 4:00 PM PST. Due to an inversion and stagnant air conditions, poor air quality is expected to develop this evening and continue through Wednesday. This may pose health risks, especially for individuals with respiratory problems. It is advised to limit outdoor exertion and to follow any additional instructions from local health officials during this period.
