CALIFORNIA FLOW REPORT

Last Updated: December 22, 2025

California's river systems are presenting varied streamflow conditions that are of great interest to river enthusiasts and water resource managers alike. In particular, the Colorado River below Parker Dam is flowing at 2300 cubic feet per second (cfs), which is lower than normal, and the stream gauge height at Yuma Main Canal indicates a decrease, suggesting potential flow drought conditions in that region. However, in contrast, the Upper Truckee River above Meyers has seen a significant increase in flow to 273 cfs, showing an impressive 673.59% of normal flow which could entice whitewater aficionados looking for rapids but also raise caution for potential flooding. Additionally, the Smith River near Crescent City is experiencing abnormally high streamflow at 29500 cfs, well above the normal, indicating that the region may face flooding if such trends continue.

Several rivers across the state are seeing large streamflow increases, highlighting the need for attention to changing conditions. The Truckee River near Truckee features a flow of 1480 cfs, a sizeable increase that suggests heightened activity for whitewater trails and possibly the risk of flooding near communities. The Mad River above Ruth Reservoir has surged to 6310 cfs, a figure that stands out as 762.5% of the typical flow. The Eel River at Fort Seward and the Van Duzen River near Bridgeville are showing significant flow increases as well, indicating that these watersheds may be experiencing early spring melt or precipitation events that could impact local water systems and recreation areas. With the potential for rapid changes in river conditions, enthusiasts and residents in areas like Yuma, Crescent City, Truckee, and Fort Seward should stay updated on local water levels and exercise caution near water bodies.

       



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

December 22 2025

Residents across California are urged to prepare for a series of potentially dangerous natural events. The National Weather Service has issued High Wind Watches for multiple regions, including Mendocino and Lake Counties, the Bay Area, Central Siskiyou, and Modoc County, warning of southeast winds with gusts up to 80 mph which could lead to downed trees, power outages, and hazardous travel conditions, especially for high-profile vehicles. Concurrently, Winter Storm Watches warn of heavy snow accumulations, affecting areas above 4500 feet in Siskiyou County, parts of Modoc County, central California regions, and Yosemite National Park outside of the valley, with potential for treacherous road conditions and significant travel disruptions. Flood watches are also in place for parts of Orange County, Los Angeles County, San Bernardino County, and Malibu due to expected heavy rains. Citizens are advised to exercise extreme caution, prepare for potential power outages, and postpone travel plans if possible to avoid the risks associated with these severe weather conditions.
