# ASCII text file containing flow-weighted sediment chemistry data
# analyzed by the USGS National Stream Quality Accounting Network (1996-2000)
# Data are based upon mean loads for 1997-2000 (estimated from modeled flux for suspended sediment and median sediment chemistry concentration)
# 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
# P----- = Flow-weighted mean concentration, where ----- = WATSTORE code
