M&I Reuse for Irrigation ^ Sustainably meet M&I demands ^ The option has very good potential to reliably
rovide additional su I durin a drou ht.
^ Optimize existing and future water supplies ^ Has the ability to maximize successive uses
of non-tributary groundwater and other
legally reusable water.
^ Protect cultural values ^ It helps maintain the quality of life unique to
each basin. In residential areas it maintains
the current landscape. In rural areas, the
return flows may benefit downstream users.
Rotating Ag transfers with ^ Sustainably meet M&I demands ^ The option has very good potential to reliably
Firm Yield for Agriculture provide additional supply during a drought.
^ Sustainably meet agricultural demands ^ The option has good potential to reliably
meet agricultural demands, by contracting
with agricultural users in a rotating, yearly
basis. Storage provided firms the supply to
allow agricultural users to produce during dry
ears.
^ Provide for environmental enhancement ^ It has the potential to improve water quality
by emphasizing the cyclical retirement of
agricultural lands with higher concentrations
of ollutants of concern.
^ Protect cultural values ^ It helps maintain the quality of life unique to
each basin. In residential areas it maintains
the current landscape. In rural areas, the
return flows ma benefit downstream users.
^ Provide for operational flexibiliiy ^ Provides for short-term transfer of water to
different users/uses, while protecting water
ri hts.
M&I and Agricultural ^ Sustainably meet M&I demands, and Sustainably ^ The M&I conservation option has very good
Conservation meet agricultural demands, respectively potential to reliably provide additional supply
during a drought. The Ag conservation
option has good potential to help to reliably
meet a ricultural demands.
^ Optimize existing and future water supplies ^ These options minimize non-beneficial
consumption, help maximize successive
uses of non-tributary groundwater and other
legally reusable water.
^ Promote cost effectiveness ^ Moderate levels of M&I conservation, and
introduction of canal lining, sprinklers, and
drip irrigation are cost competitive with other
alternative sources of water.
^ Protects cultural values ^ Although M&I conservation requires changes
in consumer behavior and may impact
landscape to some extent, agricultural
conservation improves reliabiliiy of supply
and makes a riculture viable.

^ Protect cultural values ^ It helps maintain the quality of life unique to
each basin in residential areas where it
maintains the current landscape. In rural
areas, existing water rights are used by
