ses is somewhat doubtful. Such construction would involve the
flooding of 13 miles of road, which, however, would not involve a great
loss of invested capital, as the roads generally are of a poor
character.
A second alternative would involve the construction of a dam across the
Millington gorge, 550 feet long and 30 feet high, raising the water to
240 feet above sea level and creating a lake of 14.40 square miles. This
would conserve 4,026,000,000 cubic feet, equal to 2.69 feet on the
drainage area. This would be ample for flood purposes and would still
afford a large impounded area, as the drawing off of an amount equal to
10 or even 15 inches on the watershed would not reduce the size of the
lake to any great extent.
The whole project here presented involves few difficulties, and as the
drainage area above is of small extent, the mere question of conserving
the flood waters could be met without great difficulty. The natural
advantages, however, are so great and the land included within Great
Passaic Swamp is of so little value that the surrounding country would
be improved and beautified by the construction of such a reservoir. The
opportunity for varying the character of the reservoir to meet the ideas
of those interested seems unexampled, and as a whole it presents an
extremely interesting field which may be profitably exploited.
SADDLE RIVER.
This stream has been described in the report on the flood of 1902,
already referred to. It contributes a large amount of water to the main
artery of the Passaic below Dundee dam, and as the river channel at that
point is overburdened under the present conditions because of lack of
slope and numerous catchments, together with what is known as the
Wallington Bend, it increases very materially the damage caused by
floods.
The most effectual remedy in the case of Saddle River floods is that of
construction of flood catchments. No studies have been made of the
situation in the Saddle River drainage area, but a superficial
inspection of the basin shows that opportunities for the construction of
flood-catchment reservoirs are not numerous.
SUMMARY OF FLOOD-CATCHMENT PROJECTS.
By following the plans described in the preceding pages absolute flood
catchments may be provided above Little Falls on the Passaic Basin for
551.7 square miles, leaving only 221.2 square miles from which flood
run-off would flow immediately. The accomplishment of this would involve
the cons
