OREGON FLOW REPORT

Last Updated: December 15, 2025

River conditions in Oregon are experiencing notable fluctuations with several areas reporting below-normal streamflows, indicative of a trend towards drier conditions in some watersheds. The Rogue River near Grants Pass, a popular whitewater destination, is flowing at 1,460 cfs, significantly below the normal (53.19% below normal), which may affect recreational activities. Similarly, the Illinois River near Kerby is at a mere 129 cfs, a dramatic 93.54% below its typical flow, signaling potential ecological impacts. The Umpqua River, vital for both wildlife and communities like Elkton, is flowing at only 1,800 cfs, well below its expected volume (77.45% below normal). Meanwhile, the Klamath River, essential for the region's ecology and economy, is showing mixed signals with the section below John C. Boyle Powerplant flowing higher than average at 874 cfs (57.52% above normal), while the Link River At Klamath Falls is around the expected level at 739 cfs.

On the other hand, the Columbia River at The Dalles, crucial for hydroelectric power and shipping, is near its expected flow at 118,000 cfs, only slightly above the norm (2.92% above normal). Similarly, the Hood River at Tucker Bridge is flowing at a substantial 2,770 cfs, a striking 168.22% above the normal flow, which could attract whitewater enthusiasts but also raise concerns for potential flooding. The Willamette River, which passes through major cities like Portland, Salem, and Corvallis, is below normal across the board, with the section at Corvallis reporting 10,000 cfs, 25.68% below the expected streamflow. These conditions may affect water sports, fishing, and water supply management. The low streamflow trends underscore a need for careful monitoring and conservation measures, particularly as they may impact water availability, recreation, and fish habitats across Oregon's diverse river systems.

       



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 15 2025

Residents of Oregon are urged to exercise caution as the National Weather Service has issued multiple wind advisories and high wind watches across the state. In particular, the North and Central Coast Range Mountains, Willapa Hills, and the Foothills of the Southern Blue Mountains are expected to experience southwest winds ranging from 15 to 35 mph with gusts up to 60 mph, potentially leading to downed trees and power outages. Areas such as the Eastern Columbia River Gorge and the Lower Columbia Basin are also on alert. The strongest wind gusts, especially in the Willapa Hills, are likely between 8 AM and 2 PM today. High profile vehicles may face travel difficulties, and unsecured objects are at risk of being blown around. Additional impacts may include the transition of heavy rain to snow in the Cascades, where there is a possibility of significant snowfall leading to difficult mountain driving conditions and a risk of rock and mudslides in steep terrain and near burn scars. Citizens in these regions should prepare for the inclement weather and stay informed on the latest updates.
