year 1978.
The Secretary of thf> Interior
rt'Qu~ted an environmental ...tudy for
po...sible allernati\ie sitt..., for the
Intermoun(d;n Power Project that will
have les... impach on air quality at the
Capitol Reef National Park and the
Canyonlands National Park. The...e
ahernative ...ite... \....ould be from 50 to
70 mile... northt'r1y of the pr~ently
propo...ed ...itt' near the Capitol Rt'ef

The Bureau 01 Reclamdtion
awarded a $12.7 million contract for
the con...truction of T~'zack Dam, d

around Vernal, Utah.
The Bureau of Rfflamdtion
awardNl a $4.2 million contract for
power intakt' structure modification...
on the flilmlng Corgf' Ddm. Sinct' the
reservoir wa... filll:'d in the late 1960'...,
the water released through the dam's
powerplant has bt't'n too cold for
ideal trout production and ...urvival. By
modifying the powl'rplant intakes on
the upstream sidE' of the ddm ...0 that
water can be wlthdrdwn from a le\lt"
nearer the warmer surface, water
temperatures can be raised by 10 to
15 deRrees, which is e).pt>cted to
restore river trout fishing.
The Bureau of Reclamation
awarded a $5.5 million contract to
lurnish and lay about ]J mile... of 6-

available an irrigation diStribution
system for appro\imatelv 8,800 acres.
Also, the Bureau awarded a $6 million
contrdcl for the construction of 11.4

]7-mil{' Strawbern Aqut>duct, a
system of rest'f\oirs and dl\ersion
facilities to collect \\aler irom high
mountain Slreilm~ and transport it to
the enlarRro Stril\\berf\ Re~ervolr for

transfer of water for domestic and
industrial uses in Salt Lakt' County,
and for supplemental irrig.'ltion wdtt'r
for farms in Utah and Juab Counties
and other counties in the central pan
of the State.
The 8ureau of Rffldmation
awarded d $12.] million contrJ.Ct for
the construction of a 10.7 milt'
undNground condUit and diversion
sys!pm .....hich will supply part of tht'
water for generating hydroelfftricitv
dt the ML Eiben Pumped Stordge
Powerpldnt near Leadvillt', Colorado.
The conduit is a part of a com pIe).
system of collpction tunnels and
regulating reservoirs of the
ftvin/?pdn.Ark,Jn.Y5 Project. which
diverts water from the we...t slope of
the Continentdl Dividf' to the
Arkansas River Basin on the edst sidt'
01 the mountain range. \Vhen
comple!ed, the Ml. Elbert
pump-generator fdCility will supply
200 m~awatts of peaking pow!;"r to
customt"rs in Colorado.
The Bureau of Rl:'Clamdtion on June
1, 1977, increased the rdte charged to
customers for commNcidl
hydroplfftric po.....er from the
