LOUISIANA FLOW REPORT
Last Updated: January 1, 2026
Louisiana's streamflow report reveals noteworthy trends and fluctuations in river conditions that are pivotal for water enthusiasts and communities along these waterways. Across the state, rivers are experiencing significantly lower than normal streamflows, with many showing decreases in the last 24 hours. For example, the Pearl River near Bogalusa and the Bogue Chitto River near Bush are flowing at a mere 12.3% and 16.12% of their normal rates, indicating a state of flow drought that could impact local ecosystems and water recreation activities. Similarly, the Mississippi River at Baton Rouge, a major water artery, is flowing at 37.43% of its normal rate, with a slight increase in streamflow over the past day, which is a critical point for shipping and industry. Areas around major rivers such as the Atchafalaya and the Mississippi, including cities like Baton Rouge and Morgan City, should be vigilant for potential impacts due to these abnormal flow conditions.
Specifically, the Boeuf River near Girard is flowing at 54.66% of the norm, and the Vermilion River at Perry has seen a notable 24-hour increase of 35.88%, potentially signaling a trend towards normalization or even localized flooding if trends continue. The Lower Atchafalaya River at Morgan City and the Wax Lake Outlet at Calumet are also below normal but showed a decrease in streamflow, possibly reflecting recent weather patterns or upstream water management decisions. The Bayou Lafourche at Thibodaux stands out with a streamflow at 112.53% of normal, which could interest whitewater enthusiasts if this trend leads to more challenging conditions. Conversely, the Bayou Pierre near Lake End is at a critically low 5.58% of its normal streamflow, which could severely restrict any recreational river activities. These observations serve as a reminder of the dynamic nature of Louisiana's river systems and the need for ongoing monitoring to ensure the safety and enjoyment of all who rely on these waters.
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.
