During the past year, Fan tenelle Reservoir
was operated for hydroelectric generation, flood
control, fish and wildlife enhancement, and for
recreation. During the fall and winter of 1973-74,
the reservoir was slowly reduced from elevation
6,505 feet at the beginning of the water year to
a low elevation of 6,480 feet prior to spring runoff
in April. The minimum release during the fall and
winter was 700 cubic feet per second (ft3js) in
order that power could be generated at the
powerplant and fish flows maintained. Releases
during March were high enough to force the geese
in the Seedskadee National Bird Refuge to build
their nests on higher ground. After the actual geese
nesting and hatching period, releases were
controlled to allow the reservoir to fill late in June_
Maximum releases of 8,800 ft3js from the reservoir
occurred late in June. The reservoir as of
September 30, ]974, had 315,000 acre-feet of
active storage at elevation 6,502 feet. (Chart 1)
