             Each file contains the daily values of streamflow in
                 cubic feet per second (CFS) for one station.
      The filename is ssssssss.DMV where ssssssss is the station number.

      There are 31 records for each calendar year - one record for each day (1
   through 31) of the month.  Each record contains the 12 values corresponding
   to that day in each of the months (January through December) of the calendar
   year.  Printing the 31 records for a single calendar year (cccc) in order of
   day-of-month would produce a table appearing as (missing values are 
   indicated by -999999.):

   ssssssss cccc  1 Q_Jan_1 Q_Feb_1 Q_Mar_1 Q_Apr_1   ...   Q_Dec_1
   ssssssss cccc  2 Q_Jan_2 Q_Feb_2 Q_Mar_2 Q_Apr_2   ...   Q_Dec_2

   where ssssssss is the station number.


             The file is sorted on calendar year (columns 10-13) and
                   day-of-month (columns 15-16) within that.

Note:

(1)  The field for a non-existent day - for example, November 31 or
     September 31 - is a missing value indicator of -999999.

(2)  Negative streamflow values indicate reverse flow resulting from wind,
     backwater, or tidal effects.


Conversion factor:

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