Total 11.83
From the above tables it may be seen that the maximum rate of
precipitation per hour was 1.38 inches at New York and 1.2 inches at
Newark. Comparison of the tables on pages 11 and 12 gives an excellent
idea of the intensity of the storm. The amount of water falling in a
single storm is nearly equal to the total for June, a month of unusual
precipitation.
The average of the total amounts of precipitation recorded at the
various stations in the Passaic area is 11.74 inches. These totals are
fairly uniform, none of them varying widely from the average. Therefore
the figure 11.74 represents a conservative mean for a calculation of
total amount of water over the drainage area. Assuming this as the
correct depth, the amount of water which fell on each square mile of the
Passaic drainage area during the storm was 27,273,000 cubic feet, or for
the whole Passaic drainage area over 27,000,000,000 cubic feet, weighing
about 852,000,000 tons.
