IDAHO FLOW REPORT

Last Updated: December 26, 2025

Streamflow levels across Idaho are currently 155.0% of normal, with the Pend Oreille River At Newport Wa reporting the highest discharge in the state with 35200cfs and gauge stage of 37.9 ft. Meanwhile, the Bruneau River Nr Hot Spring Id is seeing a spike in streamflows today after experiencing a 121.47% increase since yesterday, and currently running at 361cfs.

Maximum gauge stage in the state was last observed at the Sf Coeur D Alene River Abv Pine Cr Nr Pinehurst Id, currently reporting a stage of 89.68ft. The Weiser River Nr Cambridge Id in the Weiser watershed is surging for this time of year at 2120cfs, about 641.17% of normal.

       



Idaho's flow conditions are influenced by its unique hydrology and climate characteristics. The state has numerous major surface flows, including the Snake River, Salmon River, and Clearwater River, all of which are important for irrigation, hydroelectric power, and recreation. Idaho also has several large reservoirs and dams, such as the Boise River Reservoir and Lucky Peak Dam, which play a crucial role in regulating water flow and supply. The state's watersheds and snowpack levels are also significant indicators of hydrologic conditions, with winter snowpack providing a critical source of water for the state's rivers and streams during the summer months. Overall, Idaho's flow conditions are shaped by a complex interplay of natural and human factors, making it an important area of study for hydrologists and water resource managers.


       

Winter Storm Warnings

December 26 2025

Residents across Idaho are advised to exercise caution as multiple winter weather advisories and storm warnings are in effect. Heavy snowfall with accumulations of 4 to 18 inches, depending on elevation, and wind gusts up to 50 mph are expected, impacting travel and creating hazardous conditions. Areas including Frank Church Wilderness, Big Lost Highlands, Copper Basin, Sawtooth/Stanley Basin, Sun Valley Region, the Boise and West Central Mountains, and the Bear River Range will be significantly affected. Conditions could be treacherous on roads, especially around higher passes like Lolo Pass and Lookout Pass. Avalanches pose a high risk in the Sawtooth Mountains. Residents should prepare for difficult travel, potential road closures, and consider altering plans until the advisories expire on December 27.
