             Each file contains the daily values of streamflow in
                 cubic feet per second (CFS) for one station.
      The filename is nnnnnnnn.BDV 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.
 13-1500  372R*4 A 12 column by 31 row matrix holding the daily values of
                    streamflow in cubic feet per second.  Each daily value is a
                    4-byte real (floating point) value.  The values are in
                    chronological order as Oct. 1, Oct 2, ..., Sep. 31.  The
                    field for a non-existent day - for example, November 31 or
                    September 31 - contains the value -99.0.


Conversion factor:

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