HALLS BAYOU (BRAZORIA COUNTY)
HALLS BAYOU (Brazoria County). Halls Bayou rises eighteen miles northeast of Angleton in extreme northeastern Brazoria County (at 29°23' N, 95°12' W) and runs southeast for 18½ miles past Halls Bayou Camp, briefly into Galveston County, parallel to the Galveston county line into Halls Lake, through the Narrows, and into Chocolate Bay (at 29°12' N, 95°06' W). The stream is probably named for Jacob Hall, who held a land grant on its east bank. Cloud Bayou forms a major tributary. Halls Bayou, which is intermittent in its upper reaches, initially traverses flat to rolling terrain with local escarpments, surfaced by deep, fine sandy loam soils that support conifers. In its lower reaches the stream passes first through flat terrain with local shallow depressions, surfaced by clay loam and sandy loam soils that support water-tolerant hardwoods, conifers, and grasses, and then through flat to rolling prairie vegetated by mesquite, grasses, and cacti, before reaching its mouth in terrain similar to that at its headwaters.
