Activity Three: Synthesis of Other Planning Studv Information-Literature Review.
(Febl1lary 1974-0ctober 1974). Volumetric water use projections by major water using
sectors will be extracted from the framework studies, the first national assessment and
other regional studies, and interpolated to Assessment time points (1975, 1985, and 2000)
for comparison with the 1975 Assessment's water requirement projections. The major
population, economic activity, and technical coefficient assumptions underlying these
projections will be extracted for subsequent comparison with the 1975 Assessmcnt assump-
tions. In conducting this activity, othcr infomlation relevant to the conduct of subsequent
assessment activities will be listed and passed on for documentation in Phase V, Activity 2 of
the nationwide analysis.

Phase II. Central-Case Volumetric Adequacy AllalI'sis

Activity One: VolulIletric Adequacy Analysis on Central Case. (November 1974-
December 1974) Projectcd withdrawal and consumptive uses will be compared against
1975 supply estimates on both an annual and a monthly basis. For specified probabilities
of occurrence, future instream now levels (the amount of water available for release from
ASA) resulting from projected level of consumptive llse will be computed for each ASA
on an annual and monthly basis. These computed future-condition instrealll now levels
will be used to show the relative severity of volumetric deficiencies in each ASA and also
used as an input in the nonvolumetric adequacy analyses. Subsequently, as part of the
problem identification activity, the requirements and supply comparisons will be analyzed
to identify deficiencies caused by connicts in use for further evaluation.

Agency Responsiblc: NPA Work Croup assisted by WRC staff.

Activity Two: Comparison of Other Pla.nning 51l1dies with Central-Case Results.
(December 1974) The volumetric water use obtained in Phase I, Activity Three, from other
planning studies will be compared with the 1975 Assessment's central-case projections.
Where major differences in the water requirement projections are revealed, the significant
differences in assumptions responsible for the projection differences will be identified and
described.

Actil'itI' Three: Compilation of Central-Case Volumetric Information for Regional
Sponsors. (January 1975-February 1975) The results of the volumetric adequacy analysis
and the projected water requirements on which they are based, along with the information
ex tracted from other planning studies, will be compiled and provided to the regional
sponsors for their use as they conduct specific-problem analysis activities.
