OKLAHOMA FLOW REPORT
Last Updated: December 25, 2025
Streamflow conditions across Oklahoma's rivers and waterways show a mix of below-average flows and notable fluctuations that are of interest to river enthusiasts. The Arkansas River at Tulsa is currently experiencing a higher-than-normal streamflow, with measurements at 10,300 cubic feet per second (cfs) and a gage height of 4.0 feet, which is 7.5 percent above normal. This could be indicative of potential flooding and is worth monitoring for those near the area. On the other hand, critically low flows are observed in the Illinois River near Gore, with a flow of 106 cfs, a staggering 91.42 percent below the normal rate, signifying a severe flow drought that could impact local ecosystems and recreational activities.
The Cimarron River shows variability across its path through Oklahoma, with the Near Waynoka site at 58.04 percent of normal streamflow, while the Near Guthrie site is slightly below normal at -2.31 percent. The Verdigris River Near Claremore also experiences a significant drop in flow at 49.06 percent below normal. Outdoor enthusiasts and whitewater aficionados should note these deviations from typical flows. Such fluctuations can affect popular whitewater trails, as well as fish and wildlife in these watersheds. The Canadian River, an important waterway running through multiple Oklahoma communities, shows a decrease in flow across several locations, including a 38.81 percent reduction at Calvin. These trends are critical for municipal water managers and recreational users to consider. The flow data further highlight the need for careful water resource management and underscore the impact seasonal patterns have on streamflows, which can lead to either flooding or drought conditions in different parts of the state.
Oklahoma has a humid subtropical climate with frequent thunderstorms and occasional tornadoes. The state is home to major surface flows, including the Arkansas, Canadian, and Red Rivers. These rivers are subject to flooding during periods of heavy rainfall. Major reservoirs and dams, such as the Keystone Dam on the Arkansas River, help to manage flood control and provide water for agriculture and drinking water. Oklahoma's hydrology is influenced by its geology, which includes karst formations and oil and gas extraction. Watershed and snowpack data are not significant factors in Oklahoma's hydrology due to its low snowfall and lack of major mountain ranges.
Winter Storm Warnings
December 25 2025
Residents of Oklahoma, particularly in Carter, Jefferson, Stephens, Comanche, Cotton, Greer, Harmon, Jackson, Kiowa, Grant, Kay, and Alfalfa Counties, are advised to exercise caution due to a Dense Fog Advisory in effect until 10 AM CST this morning. The National Weather Service in Norman warns of visibility less than one mile, and in some areas, as low as a quarter mile. This reduced visibility can lead to hazardous driving conditions. Major cities and towns affected should prepare for potential travel delays and are encouraged to drive with heightened awareness and use appropriate fog lights or low beams. Please stay safe and consider delaying travel until visibility improves.
