This report documents and summarizes physical, chemical, and biological data collected during 1999-2004 in a study titled Effects of Urbanization on Stream Ecosystems (EUSE), undertaken as part of the U.S. Geological Survey’s (USGS) National Water-Quality Assessment (NAWQA) Program. This study was conducted to examine differences in physical, chemical, and biological characteristics of streams across a gradient of urban-development intensity in each of nine metropolitan study areas that represent distinct environmental settings across the United States: Atlanta, Georgia (abbreviations ATL and ACFB are used in figures and data tables associated with this report); Birmingham, Alabama (BIR, MOBL); Boston, Massachusetts (BOS, NECB); Dallas-Fort Worth, Texas (DFW, TRIN); Denver, Colorado (DEN, SPLT); Milwaukee-Green Bay, Wisconsin (MGB, WMIC); Portland, Oregon (POR, WILL); Raleigh, North Carolina (RAL, ALBE); and Salt Lake City, Utah (SLC, GRSL) (fig. 1). Further information about the study can be obtained at the EUSE Web site.
