21718-Extreme North End of Lower Lock Showing Immense Steel Monolith Forms on Tracks,
Used in Construction Work, Gatun, Panama Canal.


An idea of the immensity of the lock walls
may be gained by carefully observing the
large monolith forms, with seven different
platforms, which are used in their construc-
tion. The walls at Gatun, as well as at the
Pedro Miguel and Miraflores locks, are of
concrete.
The spillway from the Gatun Dam to the
tide-water level will be an opening lined with
concrete also. In this spillway there will
be 225,000 cubic yards of concrete. To regu-
late the water-level in the lake the spillway
will be closed by a dam of concrete. The


dam will be regulated by gates. The width
of the spillway is 300 feet, and the length,
1200 feet. It is cut through a veritable hill
of rock, just near the center of the large
Gatun Dam.
The Gatun Dam forms a break-water to
the Gatun Lake, whose surface will be 80
feet above the bottom of the lowermost lock.
This dam is constructed from a natural com-
bination of clay and sand. These have been
dredged by hydraulic processes from neigh-
boring pits, and then placed between two
large masses of rock and other similar ma-
terial,
