annual cost; estimates of power revenues; and the e:;ltimated production cost

for the water supply. The results of these activities are considered prelimi-

nary at this stage because of the limited geotechnical exploration progr'am.

The detailed scope of the feasibility and preliminary design study
services for the Pl"Oject is summarized as follows:

o Review resource infonnation and data applicable to the Proj-

ect which are available through State, Federal, and other

agencies.

o Participate in meetings of the Una Reservoir advisory
committee.

o Conduct a reconnaissance of the Project area to assess the
physical conditions of the site, the suitability of existing
data, and the need for additional topogr'aphic and geotechni-
cal infonnation.

o PerfoI"lll geologic mapping of the dam and reservoir site; con-

duct limited subsurface investigations (not including core

boring) to supplement existing infoI"lllation concerning foun-

dation conditions and to locate construction material

sources; review regional geology, determine fault locations,

investigate seismicity, and conduct preliminary seismic

hazard evaluations; and conduct other investigations as

necessary to select the dam axis, the type of dam, evaluate

foundation conditions, and deteI"llline necessary foundation

treatment.

o PerfoI"lll control and gr'ound sU!"veys, as required, to supple-
ment existing data.

o

Conduct analyses
accumulation in

of the flood hydrology and possible sediment
