This plan proposes a comprehensive program framework encompassi'ng four
broad phases (note figure 2) with reviews and separate decisions
between each:

"

1. Planning Phase
2. Confirmatory Phase
3. Demonstration Phase
4. Operational Phase

The first three phases are essentially research and confirmatory in
nature. The Planning Phase was initiated with congressional funding
in fiscal years 1978 and 1979 and should be completed, with detailed
designs, by 1983. Planning to date has included many public discus-
sions leading to this conceptual plan and the winter exploratory
field and other studies in 1978 and 1979. The proposed Confirmatory
Phase includes a confirmatory experiment and associated research of
cloud seeding impacts and issues. Results and experiences from other
research projects, especially the Bureau's Sierra Cooperative Pilot
Project in California and Nevada, will provide substantial input to
the confirmatory experiment designs. These first two phases will be
further described in further detail later in this plan.

.

The Demonstration Phase, a broad-scale water production test, could
'begin in the late 1980's and would be based on results of the confirma-
tory experiment, other research, and a series of basinwide preparatory
