Future Water Supply Require.ents

After evaluating the plans of individual water providers for developing
additional water supplies to meet future requirements, no basis could be
established for quantifying the yields of future water supply acquisitions
with reasonable certainty, Consequently, no estimates of the yields from
future water supply acquisitions were made. This approach was maintained
for agricultural water supplies acquired by water providers but not changed
to municipal or industrial use through a Water Court proceeding.

Without speculating on potential yields from future water supplies which
were not actually available for M&I use at the time of this study, future
water supply requirements were characterized by contrasting the safe yield
from available supplies with future demands. This provided a measure of the
water supplies that need to be acquired by each M&I water provider through
the study period..

Using this approach, additional water supplies having a safe yield of nearly
51,000 ac-ft were indicated to be needed for Study Area 1 by the year 2020.
For Study Areas 2 and 3, it was estimated that additional water supplies
having safe yields of about 16,000 ac-ft and 124,000 ac-ft, respectively,
would be needed. Future water supplies needed for Study Areas 2 and 3 could
be even larger given the concerns regarding water quality of ground water
supplies presently being used.

Potential Gains fro. Regional Integration of Supplies

Not all of the retail water providers in the study area are projected to
experience shortages in the future even without increasing the available
water supply. That is, the water supplies available to some of the water
providing entities exceed projected demands through the year 2020. Conse-
quently, projected shortages could be reduced, if not entirely offset in
some cases, by establishing a framework and the facilities necessary for
expanded regional cooperation between water providers. With addition coop-
eration and equitable compensation, the surplus supplies from one entity
