21731--Site of "Gatun Dam Looking T ward Gatun Lake, Panama Canal.
In this view we are looking along the The Gatun Dam which impounds these
western side of the Gatun locks over the x aters measures on its crest nearly i12
dam, with the waters of Gatun Lake extend- riles. The width of this great dam is nearly
ing out into the distance. Further to the h.lf a mile at its base, ioo feet at the top,
right, i. e. the west, of this view is the spill- and nearly 400 feet at the surface of the
way described in views 21732, 21733. One v-ater. The dc.m is really nothing more
of the emergency dams (see views 21726, than an artificial ridge across the lower end
21728, 21730) is plainly visible at the term of the Chzcgres Valley, which thus becomes
nus of the lock wall. The irregular line of a huge reserve ir. It is gratifying to note
the distant horizon reminds us that the great that only 5co feet of the whole length of the
artificial lake formed here is fed by the 9dam will have to stand the pressure of 85
waters from the river Chagres and other feet of water. The natural slope of the
tributary streams flowing down from the ground protects the rest.
