The main dam as II stands now
Is OF rock-filled crib type and has a
concrete apron on the downstream
side about 10 feet wide. IL Is about
f2t feet long between its concrete
,abutments, with its base about AZ
feet wide and crest ~ feet wide
and is about 1 feet in height above
the subsllls.
Three buildings comprise the
power house. The east building was
constructed In 1907 OF steel rein
forced concrete. with reinforced con-
crete roof on steel-relnforced trusses
and houses four 1I00-horsepower
turbines directly connected to four
500 kya generators. The west build
ing. OF generally similar type OF con-
struction, but with slate roof and
steel trusses. was built In 1910 and
houses two i00-horsepower verti-
cal turbines directly connected TO
two $50 kva generators. A switch
board balcony runs along the west
and north sides of the building and
IL used for high tension switching
purposes. The central building, con
Meeting the other two aud built
around the original house. follows
the same general type OF construc-
ton and houses four t75O-horsepow-
or vertical turbines directly connect
ed to four 1850 kya generators. A
balcony ON the north side of this
building Is used for switching pur-
poses. In each OF the buildings IL a
