WYOMING FLOW REPORT

Last Updated: January 2, 2026

Wyoming's river systems are experiencing a varied pattern of streamflow as we transition through the seasons. The Wind River at Riverton boasts a significant increase of 25.87% over the last 24 hours, reaching a robust 506 cubic feet per second (cfs), indicating a trend that may pique the interest of whitewater enthusiasts. Contrarily, the Little Wind River near Riverton reports a decrease of 13.94%, with streamflow levels at a low of 142 cfs. Notably, the Dinwoody Creek above Lakes has surged remarkably by 46.34% and is flowing at 248.03% of its normal rate, which could signal potential flooding if this trend continues. Water enthusiasts and residents in affected areas should remain vigilant to these dynamic changes.

In specific river systems, the North Fork Shoshone River at Wapiti has experienced a dramatic rise, with streamflow skyrocketing by 110.8% in one day, reaching 527 cfs, well above the normal rate by 133.19%. This significant change is vital for river users to note, as such a rapid increase could impact river conditions and safety. Meanwhile, the Bighorn River at Kane is flowing at a steady 1340 cfs, having seen an 8.94% rise and maintaining a flow rate close to the seasonal average. The Snake River near Moran, a river of interest for its whitewater trails, has maintained a consistent flow with a slight increase of 3.94% at 817 cfs, while the Green River near Green River, Wyoming, has marked a substantial flow of 1050 cfs, which is 32.97% above the norm for this time of year. As a state with a diverse range of waterways, these figures are crucial for those reliant on river conditions, from recreational users to communities that may be impacted by water level fluctuations.

       



Wyoming has a semi-arid climate with an average annual precipitation of 14 inches. The state contains major surface flows such as the Green River, North Platte River, and the Snake River. The Wind River Range contains the headwaters of the Green and Snake Rivers. The state has many reservoirs and dams that are used for irrigation, flood control, and hydroelectric power generation. Snowpack in the mountains is a critical source of water for Wyoming's rivers, and snowmelt runoff typically peaks in May and June. The state is also affected by drought conditions, which can lead to reduced water availability and increased wildfire risk. Overall, Wyoming's hydrology is influenced by its specific geography, climate, and water management practices.
