    dct:description """As part of the U.S. Geological Survey's (USGS) National Water-Quality Assessment Program (NAWQA), 
an investigation of the Missouri River Basin is being conducted to document trends in surface-water quality, 
specifically for trends in nutrients and suspended sediment.  Surface-water samples were collected from 
streams at specific sampling stations.  Water-quality characteristics at each station are influenced by the 
natural and cultural characteristics of the drainage area upstream from the sampling station.  Efficient 
quantification of the drainage area characteristics requires a digital map of the drainage area boundary 
that may be processed, together with other digital thematic maps (such as geology or land use), in a 
geographic information system (GIS).  Digital drainage-area boundary data for one stream-sampling 
station in the Missouri River Basin (MRB4) study area is included in this data release.  The drainage 
divides were identified chiefly using 1:24,000-scale hypsography.""" ;
