10-15 water tour day 2
This is Part 2 of a 3 day
trip I recently took through the California Water Project.
Day
2 found us at one of the key water storage and electrical
generating facilities in the State Water
Project, Oroville Dam. Completed in 1968, this dam is the
tallest earthen
dam in the country at 770 feet. It is also more than a mile across the
top
holding back nearly 3.5 million acre feet of Feather River water,
enough to
supply water to about 40% of California’s
urban water needs for a year. Unfortunately the water level is down
about 120
feet right now with miles of exposed shoreline and running at less that
2/3 of
its peak capacity due to prolonged drought conditions.
From
the base of the dam, we journeyed about ¼ mile
into the foot of the dam to view the massive turbine generators of the Edward Hyatt Powerplant that supply
power to the state grid. *(No photos allowed inside the
plant). In a room nearly 2 football fields in length and over
130’ high blasted out of solid granite, the facility is
utilized to generate
power as dictated by the needs of the grid. One of the numerous
advantages of
hydroelectric power is the ability to turn it on and off at will and to
generate a precise volume of power easily.

Further
downstream we found yet another of the many
resources provided by the State Water
Project, The Feather River
Salmon and
Steelhead Fish Hatchery. This marvelous facility provides a
series of
‘steps’ allowing the migratory fish to return to
their home waters to spawn.
Water temperature is carefully monitored during spawning season so that
water
released from Oroville Dam comes
from the right thermocline level of the lake to optimize the health of
the fish.
Also during the run, about 60,000 to 80,000 fish are harvested (out of
the
millions returning to the river), their eggs are fertilized and the fry
implanted with monitors so that migratory patterns may be discovered
and fish
health throughout the cycle can be examined for flaws anywhere in the
system.
The fish remains are distributed to non-profit processing plants and
local
Indian Tribes which returns about 60,000 pounds of low cost /high
protein meals
to local needy and indigent. Bet you didn’t know your water
company did that.
