Description
This dataset consists of drainage basin boundaries for 212
U.S. Geological Survey (USGS) stream sites sampled in the
National Water-Quality Assessment (NAWQA) Program, the National
Stream Quality Accounting Network (NASQAN), and the National
Monitoring Network (NMN). Of the 212 sites, 206 have
either a contributing or total drainage basin boundary, and the
remaining 6 have both a total drainage basin boundary and a
smaller contributing basin boundary. Collectively, these 218
basin boundaries have been used in a geographic information
system (GIS) to generate basin characteristics for the assessment
of trends in concentrations of pesticides streams of the United
States.
