# ASCII text file containing sub-basin yields for dissolved trace elements
# analyzed by the USGS National Stream Quality Accounting Network (1996-2000
# Yields are annual mean for 1997-2000
# Water as runoff in centimeters/square kilometer, chemicals in metric tonnes/square kilometer
# File is tab-delimited; missing fields are denoted with period (.)
# The first header contains column names
# The second header contains column formats
# Basin = Basin code:
#       miss = Mississippi Basin
#       riog = Rio Grande Basin
#       colo = Colorado Basin
#       colum = Columbia Basin
# Station = Water-quality station number
# Y----- = Yield, where ----- = constituent (water=runoff, chemical=WATSTORE code)
