Abstract
This report presents data on the status of fish, macroinvertebrates, and stream habitat collected from 10 sites in the lower (estuarine) parts of Armand and Dickinson Bayous near Galveston Bay, Texas, during summer 2000 and winter 2001. The total number of individual fish caught at the five Armand Bayou sites (2,091) was greater than at the five Dickinson Bayou sites (1,055), but the total number of fish species caught at Dickinson Bayou sites (37) was greater than at Armand Bayou sites (30). The total number of invertebrates (26,641) and the total number of invertebrate taxa (141) were both greater at Armand Bayou sites than at Dickinson Bayou sites (10,467 and 131, respectively). Among habitat data, the average sinuosity of Armand Bayou sites (1.31) was greater than that of Dickinson Bayou sites (1.14). Mean left-bank and right-bank slopes were greater at Armand Bayou sites than at Dickinson Bayou sites, although the Armand Bayou banks were lower and narrower than the Dickinson Bayou banks. The Dickinson Bayou channel was deeper at the sampling sites than the Armand Bayou channel.
