21733-End View of Gatun Spillway Where Water Flows into Forebay for Power
Purposes, Gatun, Panama Canal.
This view must be compared carefully
with the preceding view (No. 21732). The
photographer has moved toward the right
to the end of the circular dam, where it is
joined by the concrete wall shown in the
view. This wall does not border directly on
the lake but on a forebay, or indentation of
the lake. Thru the openings in this wall will
pass the water to feed the penstocks de-
scribed in views 21734 and 21735.
Here is to be constructed a gate-house
with motors and machinery for raising the
head gates of the penstockI. "'~'e resent
provisions call for three gateways letting
water into as many penstocks, which con-
duct water to the turbines; but three other
openings may at any time be made with as
many penstocks and turbines, in case there
is call for an increase of electric current.
In the picture can be seen the waters of
the Chagres still coursing toward the Atlan-
tic. The dam at the head of the spillway has
not yet been completed, and hence the lake,
in course of formation has not yet risen to
the proposed height of 85 feet above sea-
