Long-range Water Resources
Planning Schedule
During 1969 Mr. W. Don Maughan, Chief
of the Interstate Planning Branch, Depart-
ment of Water Resources, prepared a long-
range water resources planning network dia-
gram comparing the time requirements to
develop five types of water projects. Based on
this diagram, a somewhat simplified and re-
vised network diagram was prepared and is
shown on Plate 4.
Under the assumption that California
needs its next major water supply by year
2000, the diagram shows that a decision as to
which type of project or combination of
projects to construct should be made by 1979.
None of the time requirements are precise
and all are subject to change. However, the
diagram does indicate that, based on present
knowledge, an orderly schedule required to
complete the necessary work in order to meet
the 1979 date is from 10 to 13 years, as shown
on Plate 4 and the following tabulation:

The tabulation shows that a Western
States Water Project would be the water
source requiring the longest time both in
steps required prior to a decision and in the
time to complete works after a decisi,on is
made. These conclusions are consistent with
previous studies by the Colorado River
Board.

Review and Analysis of Reports
The Board staff reviews and analyzes re-
ports on water resources developments by
federal, state, local, and private agencies for
the purpose of providing factual evaluations
to aid the Board in its deliberations.

Among the more significant reports con-
cerning Regional Water Development re-
viewed during 1969 were:

1. "Water and Choice in the Colorado Basin," Na-
tional Academy of Sciences.

2. "Canadian Waters and Arid Lands, " E. Roy Tin-
ney.

J. "Oregon's Long-Range Requirements for Wa-
ter," State of Oregon, Water Resources Board.

4. "Utah Desalting Study," State of Utah, Office of
Saline Water, Atomic Energy Commission.

5. "Joint Mexico-United States Study of Combined
Nuclear Power and Desalting Plant," Joint Mex-
ico-United States Study Team.

6. "Statistical Aspects of Rain Stimulation-Prob-
lems and Prospects," Lovasich, Neyman, Scott,
and Smith, Statistical Laboratory, University of
California, Berkeley,
