Comments and qualifications on the data:
   The daily vales of discharge in the data file include some added inflow from a hydro plant of about 3% of total
   flow, beginning in 1961.  Since that time, the yearly inflow has been published in the annual report and yearly
   totals can be corrected for inflow.  Monthly corrected totals have been published since 1971. Monthly inflows prior
   to 1971 are available for some years.  Subject to glacier-dam outbursts in some years.

Monthly and longer averages for 41 water years are acceptable (all years except partial years).
A water year with acceptable data is indicated by an asterisk in the time line, which spans 1874 through 1988.
