project may produce incidental flood control benefits, this study
will assume that the reservoir's operation will not be governed
by flood control considerations.

In carrying out this work task the Contractor shall:

a. Review existing studies and other readily available
information on potential uses and locations of use for
the water that would be developed by the project.

b. Develop, in consultation with the State, estimates of
the montly percentages of total annual water demand for
use in the operation studies conducted under Task 9.

c. In conjunction with work done in the water rights
evaluation (Task 8), review the potential for major
water exchanges, which exchanges could permit direct
diversions to be made at locations upstream from Una
Reservoir, with developed water from Una providing
augmentation to downstream users.

The potential for recreational use of the reservoir will
not be studied.

Task 14 - Power Value Analysis

This task will develop the unit value of project power
(firm and secondary energy and capacity) to determine projected
power revenues and for use in ~electing the installed capacity of
the project. In carrying out this task, the Contractor shall
estimate the revenues which could be expected from the sale of
project power over the first ten years of project operation based
upon a review of power rates projected and included in existing
sales contracts by various western Colorado power marketing
entities, such as Public Service Company of Colorado and
Colorado-Ute Electric Association.

The economic value of average annual energy and of capacity
from an alternative power resource, probably a coal-fired plant,
will be based upon existing data given the projected costs of
such resources presently being planned or constructed in the
region. These economic values will be used in Task 15.

Task 15 - Selection of Power InstallJtion

The selection of the project installed capacity for each
water rights scenaric, both with and without the use of the
Placita Reservoir decree, will be based upon the cost of project
average annual energy adjusted to ~eflect the value of capac1ty
(possibly based on Dumped storage such as the Mt. Elbert Project)
in excess of the corresponding capacity of an alternative power
source, probably a coal-fired plant, producing the same energy.
