Data Series 279
National Water-Quality Assessment Program
At each study site, a wide range of data was collected from September 2002 through November 2003. Continuous stream stage and stream temperature were collected for the entire study period. Instream chemical conditions were measured synoptically 2 to 6 times, and passive samplers were deployed to detect hydrophobic organic contaminants. Measures of instream habitat conditions and samples of the macroinvertebrate, algal, and fish communities were collected once. Basin characteristics were detailed using a geographic information system (GIS).
