WYOMING FLOW REPORT

Last Updated: January 1, 2026

In Wyoming, river and stream enthusiasts should be aware of a mix of streamflow conditions across the state's waterways. Notably, the Snake River above Jackson Lake at Flagg Ranch shows a substantial increase in streamflow, reporting 501 cubic feet per second (cfs), a notable 44.09% above normal, which may interest those seeking heightened whitewater experiences. Conversely, the Little Wind River near Riverton is experiencing a flow drought with a streamflow of 142 cfs, which is 47.2% below normal, potentially impacting local water recreation and ecosystems. The Wind River at Riverton has witnessed a significant jump in streamflow over the last 24 hours, climbing by 129.71 cfs to a current flow of 402 cfs, suggesting a need for vigilance for communities and river users in the area due to possible flooding concerns.

In particular, water levels along major rivers such as the Bighorn River at Kane and the North Fork Shoshone River at Wapiti have increased, registering flows of 1230 cfs and 527 cfs, respectively, with the Shoshone showing a dramatic surge of 110.8 cfs in the last day, reaching 133.19% of the average flow, which could indicate potential flood risks or excellent conditions for experienced whitewater rafters. The Green River near Green River stands out with a flow rate of 1050 cfs, a 32.97% increase from the norm, likely impacting both recreation and local hydrology. Meanwhile, the Dinwoody Creek above Lakes presents an exceptionally high percent of normal flow at 248.03%, although the actual flow rate is a moderate 120 cfs. These figures are critical for understanding the current state of water resources, preparation for flood events, and optimal planning for water-based recreational activities in Wyoming's diverse and scenic river systems.
