       Each file contains the selected annual mean values of streamflow
                in cubic feet per second (CFS) for one station.
      The filename is nnnnnnnn.BAM where nnnnnnnn is the station number.

                    There is one record for each water year
                      for which there is acceptable data.

                The file is sorted on water year (bytes 9-12).

         The file is a binary file - not an ASCII file.  It can not be
         printed or edited.  Sending it to the screen yields nonsense.

  1-8     C*8    Station number - the 8 digit station number uniquely
                    identifying the station.
  9-12    I*4    Water year.  A water year starts in October of the calendar
                    year one year less than the water year and ends in
                    September of the calendar year the same as the water year.
                    For example, water year 1980 covers the period October 1,
                    1979 through September 30, 1980.
 13-16    R*4    Mean annual streamflow in CFS for the water year.
 17-20    R*4    Maximum daily streamflow in CFS for the water year.
 21-24    I*4    Number of days on which this maximum occurred in the water
                    year.
 25-32    C*8    Date on which the maximum daily streamflow occurred.  The form
                    of the date is yyyymmdd.  The date is blank if the maximum
                    occurred on two or more days in the water year.
 32-36    R*4    Minimum daily streamflow in CFS for the water year.
 37-40    I*4    Number of days on which this minimum occurred in the water
                    year.
 41-48    C*8    Date on which the minimum daily streamflow occurred.  The form
                    of the date is yyyymmdd.  The date is blank if the minimum
                    occurred on two or more days in the water year.


Conversion factor:

   Multiply cubic feet per second (CFS) by 0.02832 to obtain cubic meters per
second.
