21713--Looking South, Showing East Chamber of Upper Miraflores Locks,
At Miraflores, which is 9 miles from the
deep-water terminus of the canal on the Pa-
cific side and but 5 miles from tide-water,
there are two double locks. These are of the
same concrete structure and dimensions as
the one at Pedro Miguel and the tlhrcm at
Gatun, the other end of the canal. The two
locks at Miraflores give an elevation of 55
feet which, together with the 30 foot lift
given by the Miguel lock, offset the 85 foot
rise at Gatun Dam.
This view shows the upper locks at Mira-
flores (admire the flowers) in a nearly com-
pleted state of construction. Like all the
other locks it is a double lock and has twin
chambers. These upper locks open into a
small artificial lake which connects with
Pedro Miguel lock, a little over a mile dis-
tant. This lake will partially fill the Rio
Grande valley, and will be fed by streams in
the neighborhood, the two principal ones be-
ing called Pedro Miguel and Carmitillo
Rivers, respectively. This small lake will be
called Miraflores Lake. It will be held in
by a concrete dam on the Miraflores side; its
surface elevation will be 55 feet above sea
