There is an available site at
which a dam 280 feet high might be erected. At this elevation the length
along the top would be about 1,150 feet and about 2,330,000,000 cubic
feet of water would be impounded. Little benefit would be derived from
such a reservoir, as the limited drainage area affords a comparatively
small proportion of flood run-off that might be well cared for at a
lower point. For compensating purposes, however, a reservoir might be
constructed here, the capacity of which could be adjusted to the actual
demands. If the dam were raised to a height of about 280 feet from the
base the storage afforded would be equal to 176 inches on the watershed,
or about four average years of precipitation, which is far beyond all
probable storage necessities. The maximum available storage capacity is
given in this case merely to show possibilities.
PEQUANAC SYSTEM.
There are few available reservoir sites of large size along the lower
reaches of Pequanac River. In the upper basin, however, there is a
sufficient available storage capacity to afford almost complete control
of destructive floods from that part of the drainage area.
