II. DESCRIPTION OF THE ALTERNATIVES
This chapter presents the three alternatives which were carried forward as
a result of the impact assessment process. Eleven (ll) alternatives were
originally considered in detail in the EA, which were designed to achieve four
different objectives. The first objective {No Action Alternative} described the
existing Round I sales and operational conditions for Ruedi Reservoir. The
second objective (Preferred Alternative plus Alternatives 2-5) was for maximum
sale of water from Ruedi Reservoir to meet municipal, domestic. and industrial
demands. The third objective (Alternatives 6-8) was to minimize the riSK to
instream and recreational values. The fourth objective (Alternatives 9 and 10)
included hydroelectric power generation. Another alternative is added to this
FSES, called the Preferred with Conservation Measures Alternative.
The hydrological regime evaluated in this FSES is somewhat different than
that evaluated in the Draft Supplement of October 1983. Comments received on
that document concerning the hydrology caused Reclamation to review and refine
the hydrology study associated with the Preferred Alternative. The hydrology
study was adjusted to better reflect historical and projected winter operations.
The study was also corrected to properly reflect the application of the 15 and
30 percent shortages to industrial and municipal/domestic users, respectively,
as anticipated under the water sales contracts under a dry-year condition. The
hydro logy was fi na 1 i zed and deta 11 ed in a report completed in February 1988
(USDI, Bureau of Reclamation, 1988). These refinements and corrections in the
hydrulogy reduced the marketable water YIeld of the Preferrea AlternatIve trom
58,000 to 51,500 AF.

2.1 Alternatives Considered in Detail
This section describes three alternatives, two of which were selected by
Reclamation from the 11 original alternatives. The two selected are the No
Action and Preferred Alternatives which are carried over from the DSES 83-69.
The third selection is the Preferred with Conservation Measures Alternative.

No Action Alternative. Alternative Describes the Present
ODeratinQ Conditions
This alternative reflects the present level of water sales from the
reservoir and the present reservoir operational practices. The present reser-
voir operation allows for filling of the reservoir during the late spring and
.
early summer. Reservoir releases are made to meet senior water rights demands
