OREGON FLOW REPORT

Last Updated: December 31, 2025

Oregon's rivers are experiencing a range of flow conditions, with several waterways reporting lower-than-average streamflows, signaling potential flow droughts in various regions. Notably, the Rogue River at Grants Pass is flowing at 2600 cfs, 21.27% below normal, which may impact local ecosystems and water availability. The Willamette River, a major waterway that passes through significant cities like Portland, Salem, and Corvallis, is also reporting reduced flows; at Corvallis, the flow is recorded at 14900 cfs, down by 23.15%, which could affect recreational activities and water resources for these communities. Conversely, the Shitike Creek near Warm Springs showed an abnormally high percent normal of 964.67%, with a flow of 1480 cfs, raising concerns about potential flooding in that area.

White water enthusiasts should take note of the current conditions in their favorite rivers. For example, the Deschutes River, popular for its rapids, shows reduced flows near Madras at 4510 cfs, registering a 5.6% below the norm which might affect the difficulty and safety of white water trails. The North Umpqua River, another favored spot for rafting, is flowing at 8000 cfs near Niagara, which is notably 101.08% of the normal flow, offering potentially good conditions for white water activities. However, caution is advised as conditions can change rapidly. River-goers should stay alert for updates on streamflows and gage heights, especially in light of the dynamic changes observed, including the significant increase in flow at Shitike Creek and the overall trend of lower-than-normal streamflows in major rivers such as the Rogue and Willamette.

       



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 31 2025

Residents in Oregon should exercise caution as various advisories have been issued across the state. In the Lane County lowlands, a Dense Fog Advisory warns of visibility at a quarter mile or less due to dense freezing fog, creating hazardous driving conditions and potential slick surfaces, effective until 10 AM PST. There's also an Air Stagnation Advisory for regions including the foothills of the Blue Mountains, Lower Columbia Basin, and Central Oregon due to trapped pollutants and deteriorating air quality until noon PST. Moreover, the Southern Grande Ronde Valley is under a Wind Advisory with south winds up to 45 mph, posing a risk for downed tree limbs and power outages, in effect until 3 PM PST. Individuals with respiratory issues should be particularly mindful, as poor air quality may aggravate their condition. Residents are urged to stay informed and take appropriate actions to safeguard their well-being during these conditions.
