              For each of the variables (except station number),
                 a value of -99.00 indicates a missing value.

                 There is one record (line) for each station.

              The file is sorted on station number (column 1-8).

Columns  Format  Contents

  1-8     I8     Station number - the 8 digit station number uniquely
                 identifying the station.
  9-17    F9.2   Slope - Main channel slope, in feet per mile, measured at
                    points 10- and 85-percent of stream length upstream from
                    gage.
 18-26    F9.2   Length - Stream length, in miles, measured along the channel
                    from gage to basin divide.
 27-35    F9.2   Elevation - Mean basin elevation, in feet above mean sea
                    level, measured from topographic maps by transparent grid
                    sampling method (20 to 80 points in basin were sampled).
 36-44    F9.2   Percent storage - Area of lakes, ponds, and swamps in percent
                    of contributing drainage area, measured by the grid
                    sampling method.
 45-53    F9.2   Percent lake area - Area of lakes and ponds, in percent of
                    contributing drainage area, measured by the grid sampling
                    method.
 54-62    F9.2   Percent forest - Forested area, in percent of contributing
                    drainage area, measured by the grid sampling method.  The
                    resolution and scale of the underlying maps varied widely.
 63-71    F9.2   Percent glacier - Area of glaciers, in percent of contributing
                    drainage area.
 72-80    F9.2   Soil inf. - Soil index, in inches, a relative measure of
                    potential infiltration (soil water storage), from Soil
                    Conservation Service.  The soil index was determined from
                    maps that were necessarily highly generalized and may be
                    relatively coarse in resolution when applied to small
                    drainage areas.
 81-89    F9.2   Precip. - Mean annual precipitation, in inches, from U.S.
                    Weather Bureau series, "Climates of States", 1959-61: grid
                    sampling methods used if isohyetal map is available,
                    otherwise anomaly map constructed (WSP 1580-D, 1964).
 90-98    F9.2   I24,2 - Precipitation intensity; 24-hour rainfall, in inches,
                    expected on the average of one each 2 years.  (Estimated
                    from U.S. Weather Bureau Technical Paper 40 (1961) except
                    for western States where NOAA Atlas 2 exists).
 99-107   F9.2   Jan. min. - Mean minimum January temperature, in degrees F,
                    from U.S. Weather Bureau series, "Climates of States",
                    1959-61.


Conversion factors:

   Multiply inches by 25.4 to obtain millimeters.
   Multiply feet by 0.3048 to obtain meters.
   Multiply miles by 1.609 to obtain kilometers.
   Multiply feet per mile by 0.1894 to obtain meters per kilometer.
   Temperature degrees C = (degrees F -32)/ 1.8.

            decimal point.
