MISSISSIPPI FLOW REPORT
Last Updated: December 17, 2025
Mississippi's river systems are currently experiencing a significant variety of streamflow conditions, with many rivers reporting below-normal flows, while others have experienced recent increases that could raise concerns for flooding. Notable among the reduced streamflows is the Pearl River near Carthage, flowing at 222 cubic feet per second (cfs), which is markedly lower than average at 84.33% below normal. Similarly, the Big Black River at West is also low, with a flow of 111 cfs, 88.09% below its usual level. Conversely, Harland Creek near Howard is flowing at an exceptionally high 3340 cfs, which is 267.9% above normal, indicating a potential risk for flooding in that region.
The Mississippi River at Vicksburg, a major waterway for both ecological health and commercial transportation, is currently flowing at 250,000 cfs, a noticeable 51.12% below its expected level, which could impact both the river's health and shipping activities. Other rivers such as the Tombigbee, with a substantial increase in streamflow at Aberdeen Lock and Dam (up to 1950 cfs from a 1485.37 cfs change in the last 24 hours), are also on the radar for possible flooding, affecting nearby communities and popular whitewater trails. Water enthusiasts and communities along these rivers should be alert to these conditions, as streamflow changes can impact recreational opportunities, wildlife habitats, and local economies. River and water enthusiasts, especially those near Aberdeen, Howard, and Vicksburg, should stay informed about the latest water conditions and advisories.
Mississippi is a state with a humid subtropical climate, characterized by hot summers and mild winters. Major surface flows in the state include the Mississippi River, which forms the western border of the state, and its major tributaries, such as the Yazoo River and the Big Black River. There are also several large reservoirs and dams in Mississippi, including the Ross Barnett Reservoir and the Sardis Lake. The state's hydrology is influenced by its topography, which is characterized by low-lying coastal plains in the south and higher elevation regions in the north. Snowpack is generally not a significant factor in Mississippi's hydrology, but heavy rain events and tropical storms can cause flooding in low-lying areas.
