MISSISSIPPI RESERVOIR REPORT

Last Updated: December 5, 2025

Mississippi has several major reservoirs, including Grenada, Ross Barnett, and Arkabutla. These reservoirs are fed by the Yalobusha, Pearl, and Coldwater rivers, respectively. Snowpack and mountains are not relevant in this area, as Mississippi is a relatively flat state. The hydrology in the area is heavily influenced by rainfall, with seasonal trends of higher flows in the spring and lower flows in the summer. Record levels of flooding have occurred in the past, notably in 1979 when the Mississippi River flooded and caused significant damage. However, drought conditions have also been an issue in recent years, with some reservoirs experiencing low levels of water. Overall, reservoirs and dams play an important role in managing water resources in Mississippi, providing water for irrigation, drinking water, and recreation.
