Monthly and annual freshwater discharge of Hudson River at Poughkeepsie, N.Y.

Estimates of monthly and annual net discharge, in cubic feet per second, of Hudson River at Poughkeepsie, N.Y.
[Drainage area, 11,732 square miles]
Note.--These data represent, with reasonable accuracy, the net fresh-water discharge at Poughkeepsie. 
They do not, however, contain any information about the additional effect of the twice-daily
filling and emptying of the tidal prism in the lower Hudson River.  Since only 82.2 percent of the
drainage area is gaged, these figures are necessarily estimated.
