lands in the Power Irrigation Dis
trict. The elevation of the land is
about 1870 feet, and it is to be
watered from Jackson Lake reser-
voir via the Idaho Canal If the ex-
changes are made with he Empire
Irrigation district and others, but II
not, then 1t can be watered from the
Blackfoot reservoir. The name OF
Michaud Flat applies to the land on
the reservation and the Power Irrt-
CATION district to the lands west OF
the reservation. The water for all
these lands is to be carried across the
Portneuf valley near Pocatello and
under the river by means of siphon
$500 feet long and about $50 feet
below the water level of the canals.
The water will rise on the Mfchaud
side to within about forty feet of the
required level for irrigation, and will
be pumped the remaining forty feet,
using centrifugal pumps driven by
electric motors operated by power
generated by water from the Black
foot reservoir passing the diversion
dam in the Blackfoot river and by
two generating plants in the canal
leading down the Ross Fork valley,
the larger one being located in the
canyon just above the Buckskin
Basin where the water will have a
drop of $50 feet This will generate
900 horsepower and the estimated
cost of the plant is $750,000.
Other Power Sites
Power site number one will be on
the Ross Fork canal four and half
miles below the outlet Of the High
Line tunnel where the canal comes
thru the range from the head Of
the Portneuf valley. 1t will have
a drop, or head of $50 feet and a
volume of 400 second feet of water.
1t will generate 5000 horse power
at an estimated cost of $50 per horse
power, or total of 100000 for
the plant.
Power plant number two is the
one described above. Another one
at the diversion dam in the Black
foot river will operate five months
of the year and the power generated
there will be used to drive the ten
thousand foot tunnel thru the range
between the Portneuf valley and
Ross Fork Creek.
lHC 6OulCC VI vbaJCI supply
The source of water supply for
the FIT. Hall project is the Blackfoot
reservoir. The source of supply for
the Greater FIT. Hall project is chiefly
the enlarged Blackfoot reservoir, in
combination with the American Falls
reservoir and the Jackson Lake res
ervoir in exchange of water with
people in the Twin Falls and Mini
doka country, who own water in the
Jackson Lake.
The Enlarged Reservoir
its capacity increased by the enlarge
ment of the dam to raise the water
level; by stopping what is known as
The Leaks; by changing the drain
age of Grays Lake (also known as
John Days Lake, to keep it from
going via The Outlet, Willow creek
and Sand creek into the damaged
district of the Sand creek country
as at present, and turn it thru the
low divide into the drainage basin
Of the Blackfoot river into the
Blackfoot reservoir.
The volume of water in Grays lake |
is to be increased by taking the flow
of lineup creek on Caribou noun
tain, which at present drains into
Salt River in Wyoming, then into
the South Fork OF Snake river, and
turning it thru a, tunnel into Grays
Lake and the B1ackfoot reservoir.
The Leaks
The Leaks is a section of low
cliffs in the bluffs constituting part
If the southern shore Of the Black
'oot reservoir, 10 miles north of
Soda Springs, where streams of
water flow right into the rocky walls
md are lost. The reservoir Is be-
ng drained this summer SO these
