MISSOURI FLOW REPORT

Last Updated: December 4, 2025

Missouri's rivers are currently experiencing a trend of lower-than-average streamflow rates, which is notable for both conservationists and water recreation enthusiasts. The data indicates that many rivers across the state, including the Missouri River at key locations such as St. Joseph, Kansas City, and St. Charles, are flowing at rates significantly below normal, with streamflow reductions reaching as high as 47.37% below average at Jefferson City. This reduction in flow could impact various activities, from fishing to whitewater kayaking, especially in popular spots like the Meramec River near Sullivan and the Big Piney River near Big Piney, which also show decreased flows at -38.88% and -45.53% respectively. These conditions suggest a potential flow drought, warranting careful monitoring for environmental impacts and water resource management.

Of particular interest, the Big River at Byrnesville experienced a substantial 24-hour increase in streamflow of 209.72%, although it still remains below normal by -23.3%. This spike could indicate isolated heavy rainfall and may raise concerns for localized flooding. Conversely, the Moreau River near Jefferson City saw a significant decrease in streamflow over the past 24 hours, with a -28.78% change, intensifying the flow drought conditions. Water enthusiasts should be aware of these fluctuations as they could affect river navigation and safety. The current gage height at key recreational sites like the Niangua River at Windyville is at 1.4 feet, which is low for this time of year, potentially affecting the whitewater trails in the area. Overall, river-goers in Missouri should stay informed about the changing conditions and exercise caution when planning activities on or near the water.
