Halls Bayou begins six miles northeast of Alvin and flows southeasterly 15 miles to Halls Lake and ultimately into West Galveston Bay. This bayou is host to tens of thousands of waterfowl in the winter due to its extensive beds of wild celery, a submerged aquatic plant, which is a preferred waterfowl food. The bayou is bordered by native tall grass prairies and marsh wetlands and supports a diverse assemblage of freshwater and saltwater fish that provide valuable recreational fishing opportunities to local residents. Fish commonly found in the bayou include catfish, largemouth bass, speckled trout, red drum and croaker.5 The ecologically significant segment is from Halls Lake in Brazoria County upstream to FM 2004.
