critical because of the small releases during
the first two or three years when we were
acquiring minimum power operating head at
Lake Powell and Flaming Gorge Reservoirs.
We should have no difficulty selling the
power created by passing the 35 million
acre-feet thrQugh the powerplant between
now and 1972.

Flaming Gorge Reservoir is now at eleva-
tion 5992 feet and a content of 2,142,000
acre-feet, or about 8 feet lower than its
seasQnal high. It should continue to
recede to elevation 5976 by the end of
March 1969.

Fontenelle Reservoir was drawn down to
elevation 6494.5 and a content of 258,000
acre-feet during September for inspection of
the repair work and stabilization of the new
embankment. In future years the reservoir
will normally fill each spring, elevation
6506, and be dPewn down 21 feet to elevation
6485 and a content of 196,000 acre. feet late
each winter. Within this type of fluctuation,
all purposes of the pro}eet will be served
and minimum amounts of water will bypass the
powerplant.

Navajo Reservoir has been held at about
elevation 6030 feet with a content of
1,045,000 acre~feet during the past few
months for fish enhancement and recreation
uses. Recently we have initiated some
maintenance work on the main outlets which
will restrict releases from the reservoir
to about 400 second-feet from the 30-inch
bypass valve and cause the reservoir to
remain at about its present level through
November. Starting in December, the level
of the reservoir will be lowered 20 feet to
elevation 6010 and a content of 833,000 acre-
feet to move some water down~tream during the
winter months and to provide space required
for control of possible flood runoff in the
spring of 1969.
