CALIFORNIA FLOW REPORT

Last Updated: January 1, 2026

California's river systems are showing a diverse range of streamflow conditions, with some areas experiencing significant deviations from normal flow levels. For river enthusiasts and water users, it's notable that several key waterways, such as sections of the Colorado River, are currently below normal flow rates, with the Palo Verde Canal near Blythe and the Colorado River below Parker Dam displaying streamflows at approximately 60% of their average, posing potential limitations on recreational activities and water supply. In contrast, the Donner Creek at Highway 89 near Truckee is flowing at nearly 179% of its usual rate, suggesting an abundance of water for local ecosystems and possibly elevated conditions for whitewater enthusiasts.

Particularly noteworthy is the Santa Rosa Creek at Santa Rosa, showing a dramatic increase in streamflow, rising by over 295 cfs in the last 24 hours to 284 cfs. This surge indicates potential flooding risks or at least rapidly changing conditions that could impact water-based recreation and local infrastructure. In Southern California, the Santa Ynez River near Santa Barbara is recording flows over 300% above normal, which could impact the surrounding communities and ecosystems. Whitewater trails in these areas could experience unpredictable and challenging conditions. In the broader context, such variability in river conditions across California underscores the importance of ongoing monitoring for water management and safety, as well as for those engaging in river-related activities.

       



California has a diverse hydrological system with major surface flows, including the Sacramento and San Joaquin River systems, which provide water to the agricultural heartland. The state has numerous reservoirs and dams, including the Oroville Dam, which is the tallest in the US. California's climate is characterized by long periods of drought, punctuated by occasional heavy rainfall events. The state's hydrology is heavily influenced by snowpack, which accumulates in the Sierra Nevada mountains during the winter and provides a critical source of water during the dry season. The state's watersheds are also important, with the Sacramento River being the largest, providing water to much of Northern California. Overall, California's water management is complex and requires careful planning to balance the competing demands of agriculture, urban areas, and the environment.


       

Winter Storm Warnings

January 1 2026

The National Weather Service has issued multiple advisories for California, alerting residents to various weather-related dangers. A Coastal Flood Advisory is in effect until January 4, warning of potential inundation along the San Francisco Bay, San Pablo Bay, Monterey Bay, and the Pacific Coast, with high tide expected to cause increased flooding threats. Additionally, Wind Advisories and a High Wind Watch have been announced, predicting south winds with gusts up to 75 mph in areas such as Western Mendocino Interior, Humboldt, Del Norte, and Lake Counties, posing risks of downed trees and power lines. Furthermore, a Flood Advisory has been declared for Fresno and Kings Counties due to excessive rainfall, indicating a threat of minor flooding. Residents of these regions, including those in major cities like San Francisco and Eureka, should take precautions, stay informed, and be prepared for road closures and potential power outages.
