#  METADATA Data Description:  
#
#  ABSTRACT:	This file references the locations of the drainage basins for the sites analyzed in 
#	Sprague and others, 2006 (SIR 2006-5231). Data from the sites were used in a report documenting 
#	trends in the Missouri River Basin as part of the U.S. Geological Survey, National 
#	Water-Quality Assessment Program.
#
#
#  SUPPLEMENTAL INFORMATION:
#   	PROCEDURES USED:
#	PROCESS STEP:
#
#	The drainage basin boundaries were obtained from one of 2 NAWQA websites 
#	(http://water.wr.usgs.gov/pnsp/gis/data/swancil/mrb.html, or 
#	http://water.wr.usgs.gov/pnsp/gis/data/swancil/cycle2.html).  These two websites contained 
#	data that had originally been compiled from other external sources, which are further described 
#	in Sprague and others, 2006 (SIR 2006-5231).  
#
#	Basin boundary coverages were obtained from the website 
#	http://water.wr.usgs.gov/pnsp/gis/data/swancil/mrb.html for these sites:
#	06130500
#	06441500
#	06934500
#
#	Basin boundary coverages were obtained from 
#	http://water.wr.usgs.gov/pnsp/gis/data/sucovers/bas.html for these sites:
