OKLAHOMA FLOW REPORT

Last Updated: December 29, 2025

River and water enthusiasts in Oklahoma should be aware of the current diverse streamflow conditions across the state's river systems. Notably, the Arkansas River at Tulsa is experiencing streamflows above normal at 10,300 cubic feet per second (cfs), a minor rise from the last 24 hours, possibly indicating healthy water levels for activities like fishing or rafting. However, many rivers, including the Neosho River and the Illinois River, are reporting significantly lower than normal streamflows, with reductions of up to 96.58% of normal levels near Chouteau and 93.61% near Watts, respectively, which can affect water-based recreation and ecosystem health. The Cimarron River also displays below-normal streamflows across multiple locations, such as near Guthrie at 409 cfs, marking a 49.52% drop from typical levels. Such conditions suggest potential flow droughts in these regions.

In contrast, the Neosho River near Langley saw an unprecedented increase in streamflow with an astonishing 1254.26 cfs rise in the past 24 hours, causing the current streamflow to reach 604 cfs. While this is still below average for the river, it marks a significant event that could point toward potential flooding concerns for nearby communities and whitewater trails. Cities along the Canadian River like Norman should also be vigilant, as the current streamflow at this location has dipped to 193 cfs, manifesting a 69.72% decrease, paired with an unusually high gage height of 86.09 feet. This disparity indicates that flood control measures may be in effect, possibly altering natural streamflow patterns. These fluctuating conditions underscore the importance for enthusiasts and local residents to stay updated on river and streamflow conditions for safety and to anticipate the impact on water-related activities and ecosystems within Oklahoma's diverse watersheds.
