Water-quality, stream-habitat, and biological data for Highland and Marchand Bayous, Galveston County, Texas, 2006-07

Abstract

The U.S. Geological Survey, in cooperation with the Houston-Galveston Area Council and the Texas Commission on Environmental Quality, collected water-quality, streamhabitat, and biological data from five sites on Highland and Marchand Bayous in Galveston County, Texas, during 2006-07. Water-quality data-collection surveys consisted of synoptic 24-hour continuous measurements of water temperature, pH, specific conductance, and dissolved oxygen and periodically collected samples analyzed for several properties and constituents of interest. Bacteria samples were collected monthly at 10 sites on Highland and Marchand Bayous during the study. Stream-habitat data were collected at five sites three times during the
