COLORADO FLOW REPORT

Last Updated: December 22, 2025

Colorado's streamflow conditions exhibit significant variability as we move into the season, presenting challenges and opportunities for river enthusiasts and communities along the waterways. Notably, the Gore Creek near Vail has experienced an extraordinary surge in streamflow, with an increase of 1196.3 cubic feet per second (cfs), putting it at an astonishing 1007.59% of the normal flow, which is exceptionally high and likely to impact whitewater conditions in the area. Conversely, the South Platte River near Crook and Fort Morgan is experiencing flow drought, with current streamflows at -91.23% and -56.74% of normal, respectively, indicating potential water supply concerns. Cities such as Denver, Henderson, and Fort Lupton on the South Platte River should be aware of these lower streamflow levels. The Arkansas River near Parkdale, a popular destination for rafting, is flowing at 306 cfs, which is -19.26% of its normal streamflow, potentially affecting recreational activities. Additionally, the Rio Grande showcases varied conditions with the area near Lobatos seeing a high streamflow at 167.89% of normal, indicating a potential for flooding if trends continue.

In the broader context, major rivers like the Colorado, Yampa, and Gunnison have mixed streamflow reports, with locations such as the Colorado River near Dotsero flowing at -19.52% of normal, and the Gunnison River below Gunnison Tunnel at a concerning -52.52% of normal, which may impact local ecosystems and agriculture. The Yampa River at Deerlodge Park, however, is close to the norm at 2.33% above average flow, which may be favorable for river-based recreation. Gage heights across various rivers reflect these fluctuations, for instance, the Arkansas River At Canon City stands at 5.68 feet, and the Roaring Fork River At Glenwood Springs at 1.54 feet, providing essential data for monitoring water levels and preparing for any necessary response to these dynamic conditions. It's crucial for water enthusiasts and local inhabitants to stay informed on the latest streamflow data to ensure safety and optimal use of these river systems.

       



Colorado's flow conditions are largely influenced by its mountainous terrain and semi-arid climate. The state's major surface flows include the Colorado, Arkansas, Platte, and Rio Grande rivers, with the Colorado River serving as the primary water source for much of the western United States. Major reservoirs and dams include the Colorado-Big Thompson Project and the Dillon Reservoir. The state's hydrology is heavily influenced by snowpack, with winter snowfall accumulating in the mountains and melting in the spring and summer months to feed downstream water sources. Climate change has had a significant impact on Colorado's hydrology in recent years, leading to decreased snowpack and earlier melting, which can exacerbate drought conditions and impact water availability.


       

Winter Storm Warnings

December 22 2025

Residents of Colorado, particularly those in the Boulder county foothills, South Park, the Palmer Divide, and fire weather zones including 221, 222, 226, 228, 229, 239, 241, 214, 215, 216, and 238, are urged to exercise extreme caution today due to critical fire weather conditions. The National Weather Service has issued a Red Flag Warning effective from 8 AM to 5 PM MST, warning of gusty westerly winds of 10 to 30 mph with gusts up to 55 mph and very low relative humidity levels as low as 9 percent. These conditions can lead to rapid fire spread, and outdoor burning or any activities that could produce sparks are strongly discouraged.
