The effectiveness of a reservoir built upon the lines proposed in
the case of Great Piece Meadow depends upon the adjustment of
outflow so that the channel below will not be overborne, while at
the same time sufficient storage capacity is afforded to hold
temporarily the water which enters above the dam in amount greater
than the carrying capacity of the outflow apertures. The dam across
Passaic River above Little Falls would be provided with apertures
which would discharge 12,000 cubic feet per second under the
maximum head in the storage basin. As the flood rises these
apertures would discharge a constantly increasing amount of water
to the maximum, and for a considerable time thereafter the maximum
would be maintained, the discharge decreasing after the flood
according to the
