Green Mountain Reservoir

1. Primary commitments are: 52,000 acre-feet for replacement
for downstream rights; 5,000 acre-feet committed to Silt
Project and 19,500 acre-feet to Grand Valley for irrigation
use. Drawdown restrictions placed on Green Mountain Reservoir
now limits use to above-named functions plus the Atlantic
Richfield and Carter Oil Company (Subsidiary of EXXON) proposed
contracts for oil shale development on Colorado leases B and A
at 50 and 150 KBCD, respectively.

Ruedi Reservoir

1. No firm division of yield from Ruedi determined as to
replacement storage and fishery releases and water available for
marketing. Gulf-Standard of Indiana has applied to contract
for 30,000 acre-feet with delivery to begin in 1980 for oil
shale development. No contract executed.

Joes Valley

1. Under the Emery County Participating Project, 6000 AF/YR of
M&I allocation is used by Utah Power and Light Company at its
Huntington Canyon Powerplant which has one 430 MW unit.

Lake Powell

1. Navajo Powerp1ant - A consortium of power users are building
the 3 unit Navajo Powerplant along the east shore. Coal is
, transported from Black Mesa in northeast Arizona by unit train.
The first 750 Mw unit began generation in May 1974. Two addi-
tional 750 Mw units are under construction with expected in-
service dates of 1975 and 1976.

2. Resources Inc./Kaiparowits - An option contract of 102,000
AF/YR for development of a 3000 Mw coal-fired powerplant is in
force although expected water use is only 45,000 AF/YR.

Water Quality - The following tabulation presents present modified
salinity concentrations for some typical stream locations in the Upper
Colorado River Basin. Present modified refers to the historic condi-
tions (1941-1970) modified to reflect all upstream existing projects
in operation for the full 1941-1970 period.
