The constituents of the flow include water from local streams and rainfall. There are several tributaries that feed into the bayou, including the Little Bayou Bartholomew and the Bayou Macon. The bayou is also affected by the operation of the Wilhelmina Lock and Dam, which can influence seasonal trends in the water level. Interestingly, the Bayou Bartholomew is known for being heavily polluted due to agricultural runoff, and efforts are being made to improve the water quality through conservation and restoration projects.
