The primary constituents of the flow are rainfall, surface water runoff, and groundwater discharge. The bayou is fed by several tributaries, including Bayou des Allemands and Bayou Lafourche North. There are no major dams along the bayou. Seasonal trends show that flow decreases during the dry season (fall and winter) and increases during the wet season (spring and summer). Interestingly, the bayou was once used as a major transportation route, with steamboats carrying goods and passengers between New Orleans and other towns along the bayou.
