MONTANA FLOW REPORT

Last Updated: January 3, 2026

Montana's rivers and streams exhibit varied streamflow conditions, reflecting a diverse array of hydrological trends and concerns for river enthusiasts. Notably, the St. Mary River near Babb exhibits an exceptional streamflow at 1010 cubic feet per second (cfs), soaring to 371.29% of normal, which may raise concerns for potential flooding in the vicinity. Contrastingly, the Sun River at Simms, with a flow of 240 cfs at 78.88% below the norm, indicates a significant flow drought. For whitewater aficionados, the Hyalite Creek at Hyalite Reservoir South near Bozeman stands out with a 226.63% increase in streamflow over the past 24 hours, with a robust flow of 195 cfs. This spike in streamflow suggests a thrilling short-term condition for paddling pursuits. In addition, the Jefferson River near Three Forks presents a modest 2.3% below normal flow, maintaining a stable condition for river activities.

Focusing on major waterways, the Missouri River, a pivotal watershed, is seen with varying flow conditions across different locations. Near Great Falls, the river's streamflow is 4900 cfs, just 0.25% above normal with a gage height of 3.12 feet, indicating stable conditions, while at Fort Benton, it shows a slight decrease to 2% below normal levels. The Milk River at Nashua flows at 233 cfs, which is worryingly 47.49% below normal, signaling a need for water conservation efforts. Significant for whitewater trails, the Gallatin River near Gallatin Gateway has surged by 48.48%, reaching a flow of 441 cfs, closely aligning with average conditions, which could attract paddlers looking for consistent water conditions. As for cities, Missoula, situated along the Clark Fork River, should monitor the 2320 cfs flow at 49.05% above normal, which may impact urban water activities. Lastly, those interested in the Kootenai River should note the high streamflow at Libby, standing at a remarkable 21800 cfs at 151.61% of normal, which might affect both recreational use and local ecology. It's crucial for water enthusiasts and local communities to stay informed about these dynamic conditions, ensuring safe and enjoyable river experiences.

       



Montana has a varied climate and terrain that greatly affects its flow conditions. The state boasts of major rivers such as the Missouri, Yellowstone, and the Clark Fork, which drain into the Mississippi, Missouri, and Columbia Rivers, respectively. Montana also has a number of reservoirs/dams, such as the Fort Peck Dam and the Hungry Horse Dam, which serve as major power sources and water storage for the state. The state's hydrology is influenced by its mountainous terrain, which leads to high precipitation levels and generates snowpacks. These snowpacks, in turn, largely determine the state's flow conditions in the summer months. Montana's flow conditions are also affected by its climate, which is characterized by dry summers and cold winters. Overall, Montana's flow conditions are shaped by a mix of climatic and topographic factors, including watershed, snowpack, and precipitation.
