water quality in many of the Pacific
Southwest's streams, provided the water supply
of the area is augmented for this purpose and
appropriate legal protective measures are
developed.
4. Major point sources of bacteriological and
biological pollution, such as municipal and
industrial wastes, can be controlled by an
adequate number and type of treatment plants
and related facilities.
5. Pyramid and Walker Lakes and bays and
estuaries of the California coast are sensitive to
changes in quality and quantity of tributary
waters. Diversion of upstream water sources
accelerates this change and in some cases
threatens existing uses of the terminal lakes,
bays, and estuaries.
6. Waste heat in cooling water from
thermal-electric powerplants on inland waters
will be dissipated through cooling towers or, in
some cases, cooling ponds. Waste heat from
thermal-electric plants located on ocean waters
is handled by once-through systems which
release warmed water to the ocean.
7. Future water resource development plans
should provide high quality water to municipal
