This river is a vital habitat for many species of fish, including the Gulf sturgeon, and provides water for irrigation, drinking, and recreation. The river has several tributaries, including the Leaf River and the Chickasawhay River. Seasonal trends show that the river's flow peaks during the wet season, which is typically from December to May, and decreases during the dry season, which is from June to November. Additionally, the river is known for its unique hydrology, as it is one of the last free-flowing rivers in the contiguous United States, meaning that there are no dams or diversions along its course.
