LOUISIANA FLOW REPORT
Last Updated: December 4, 2025
In Louisiana, river enthusiasts are observing a variety of streamflow conditions ranging from significantly below normal flows to considerably above average. The Mississippi River at Baton Rouge, a major waterway for the state, is currently flowing at 233,000 cubic feet per second (cfs), which is 36.7% below its normal rate, with a gage height of 8.41 feet, potentially impacting commercial and recreational activities along its course. Conversely, Bayou Lafourche near Crew Lake is experiencing flow rates exceptionally above the norm at 4770 cfs, a significant 273.09% of its average, signaling potential flooding risks if such trends continue. The gage height there is at a notable 11.48 feet.
Specific streams like the Bayou Macon near Kilbourne are showing dramatic increases in flow over the last 24 hours, with streamflow changes of 211.32%, pushing its flow rate to 198 cfs, well above its usual, and raising its gage height to 7.96 feet. This rapid rise could suggest flash flooding conditions for nearby areas. On the flip side, the Amite River at Port Vincent and near Denham Springs has seen reductions in flow, running at a mere 15.49% and 35.13% of their normal rates, respectively, indicating possible flow drought conditions that could affect local ecosystems and water-based recreation. These variations in streamflow across the state underscore the need for residents and visitors to stay informed and cautious, especially those engaged in activities around whitewater trails and in flood-prone regions.
Louisiana is a state in the southern United States with a humid subtropical climate. The state has many major surface water flows, including the Mississippi River, the Atchafalaya River, the Red River, the Ouachita River, and the Sabine River. These rivers and their tributaries are subject to flooding during the state's frequent severe weather events, such as hurricanes and tropical storms. Louisiana also has numerous reservoirs and dams used for flood control and hydroelectric power generation. The state's hydrology is influenced by its flat terrain and extensive wetlands, which act as natural reservoirs. Snowpack is generally not a significant factor in Louisiana's hydrology, but heavy rainfall events can lead to flash flooding and river flooding.
