COLORADO FLOW REPORT

Last Updated: December 19, 2025

The state of Colorado showcases diverse streamflow conditions across its waterways, integral to river enthusiasts and the ecological health of the region. A notable trend is observed in the South Platte River basin, where streamflows range from below-normal levels near Northgate at 109 cfs (cubic feet per second), 40.54% below the seasonal norm, to higher flows at Fort Lupton at 358 cfs, 9.44% above normal. These variations could affect recreational activities such as whitewater rafting, particularly in popular spots like the Arkansas River at Salida, currently flowing at 239 cfs, which is 18.07% below normal. Furthermore, the significant increase in the South Platte River Near Weldona, which surged by 65.92 cfs in the last 24 hours, raises concerns for potential flooding in the adjacent areas.

For whitewater aficionados, the monumental spike in streamflow on Gore Creek above Red Sandstone Creek at Vail stands out, with an increase of 1196.3 cfs, reaching a flow of 280 cfs, a staggering 1007.59% of the norm, which may signal excellent conditions for challenging runs but also warrants caution for safety due to possible flooding. On the other end, the Gunnison River basin exhibits lower streamflow with the Gunnison River Below Gunnison Tunnel reporting a flow of 352 cfs, a substantial 51.43% below the expected level, indicating potential restrictions for river activities. Cities and watersheds along these rivers, such as Denver, Fort Morgan, and Pueblo, should remain vigilant to the dynamic conditions, particularly those along the Rio Grande, which shows elevated flows near Lobatos at 361 cfs, 167.89% above normal, hinting at a lush season for water-based recreation but also a need for awareness around water safety and potential environmental impacts.

       



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 19 2025

Colorado residents are urged to exercise extreme caution as a series of severe weather warnings have been issued across the state. A high wind warning is in effect until 8 PM MST with west winds reaching 35 to 50 mph and gusts up to 100 mph, notably impacting the Rocky Mountain National Park, Medicine Bow Range, and northern and southern Front Range Foothills. Boulder, Longmont, and western Denver suburbs face damaging winds that could down trees and power lines, posing risks of power outages and difficult travel, especially for high profile vehicles. Additionally, a critical "Particularly Dangerous Situation" Red Flag Warning is in place for the foothills of Boulder and Jefferson Counties with gusts potentially reaching 105 mph and humidity dropping alarmingly low, significantly increasing the risk of wildfires. Winter weather advisories also forecast 4 to 12 inches of snow and gusts up to 60 mph in mountain regions, including Rabbit Ears Pass and the Elkhead and Park Mountains, complicating travel with slippery roads and reduced visibility. Residents should prepare for potential power outages, avoid outdoor burning, and be prepared for rapid changes in conditions.
