<https://data.amerigeoss.org/dataset/5417cedd-cf35-4b4b-af52-3262f263c30f> a dcat:Dataset ;
    dct:description """This dataset represents 19,031 basin boundaries and their streamgage locations 
for the U.S. Geological Survey's (USGS) active and historical streamgages from 
the published dataset of Stewart and others (2006) and its subsequent updates 
(D.W. Stewart, USGS, written commun., 2011).  Only the basin boundaries that 
were delineated within 15 percent of the basin area reported in the National 
Water Information System (NWIS) were included in this dataset.  This dataset 
only includes streamgage basins in the lower 48 states and not in Alaska, 
Hawaii, or Puerto Rico. The basin boundaries and streamgage locations are 
provided in 18 shapefiles separated by 2-digit Hydrologic Unit Code. The USGS 
streamgage station's identification number attached to each delineated polygon 
can be linked to the attribute data found in Stewart and others (2006).  The 
delineated watersheds were made from digital elevation models found in the 
NHDPlus data suite (version 1, 2006) and based on gage locations provided by 
Stewart and others (2006).  These basins have been used in several USGS studies 
such as James Falcone's "GAGES-II: Geospatial Attributes of Gages for Evaluating 
Streamflow"  (2011) and Xiaodong Jian and others, "WaterWatch-Maps, Graphs, and 
Tables of Current, Recent, and Past Streamflow Conditions " (2008).""" ;
