Water Conservation Statewide is Insurance for Mono
Lake
by Frances Spivy-Weber
California's water needs are met by an intricate
array of aqueducts and dams, local water programs, and
imported water supplies. As we've seen at Mono Lake,
these complex waterworks often cause environmental
destruction.
In the spotlight recently are
the serious environmental problems happening where the
Sacramento-San Joaquin River Delta meets the San
Francisco Bay. While many miles away from Mono Lake, the
troubles of the Bay-Delta can be eased by the same wise
water uses that helped protect Mono--water conservation
and water recycling. At the same time, solutions to the
state's pressing water problems will help avert future
demands for additional Mono Basin water.
The crux of the conflict now at hand in the Bay-Delta
is how to protect the nearly 700-mile region, which
provides over 70,000 acres of wetlands and is home to
over 120 species of fish and wildlife, while meeting the
needs of urban and agricultural water users.
Currently, pumping plants in the Bay-Delta transfer
millions of acre-feet of water into the California
Aqueduct and Central Valley Project canals. Over 20
million Californians get their drinking water from this
system. Over four million acres of farmland are
irrigated. And the natural flow of water in the Bay-Delta
is reversed, killing millions of fish and decimating
California's most important wetland.
The need for a solution to the Bay-Delta problem has
been the source of decades of contentious fighting. In
1994 state and federal agencies with management and
regulatory responsibilities in the Bay-Delta came
together to seek agreement on water quality standards for
the region. Calling themselves CalFed, these agencies
launched the CalFed Bay-Delta Program in June 1995 to
seek a long-term solution to the management of the entire
Bay-Delta. The agencies planned for a consensus-based
process that would include all major stakeholders as well
as the public.
Sharing Mono's lessons
Martha Davis, former executive director and current
board member of the Mono Lake Committee, works with the
Bay-Delta Advisory Committee and helps the Mono Lake
Committee weigh in on the CalFed process, particularly in
support of wiser, more efficient policies governing the
use of water statewide.
Many Californians do not realize that the success of
Mono Lake's protection--achieved without significant
water losses to Los Angeles--can be repeated elsewhere in
the state. California has enough water to meet both the
needs of the economy and nature, now and in the future.
The Los Angeles Department of Water and Power and
other water districts, particularly in Southern
California, are beginning to acknowledge this fact. Over
the last few years DWP has committed staff and funds for
conservation, water recycling, and groundwater
management. The results are impressive. In Los Angeles,
despite a population increase of one million people,
residents are using water at levels seen in the 1970s.
The Mono Lake Committee helped raise federal and state
funds for some of LA's environmentally sound water supply
programs, more than offsetting the water now committed to
the protection and restoration of the Mono Basin
ecosystem.
The CalFed process is expected to produce a plan by
December 1998 outlining the next steps the federal and
state governments will take to restore the Bay-Delta
ecosystem--and to manage the water supply coming from
this ecosystem. The Mono Lake Committee will be posting
information on the Internet at www.monolake.org as
the recommendations unfold. Your help will be needed to
steer this recommendation in a direction that will ensure
people and the environment have fair shares of
California's water.
Creeks
flow high:
A large winter snowpack combined with hot July
weather to raise Sierra reservoirs to the
spilling point and send high flows rushing down
Mono Basin streams. The high flows were aided by
good communication between the reservoir
operators--the LA Department of Water and Power
and Edison--who to a certain degree can
coordinate the timing of releases to maximize
flows downstream.Seasonal peak flows not only
raise Mono Lake, but also provide the dynamic
energy needed to restore pools, riffles, and
meander bends in the streams. They help willows
and cottonwoods establish themselves along the
banks, which in turn capture sediment and rebuild
stream banks.
High flows during the early summer snowmelt
period are considered by scientists to be one of
the most important mechanisms for restoring the
stream habitats and processes that were
eliminated by DWP's 50 years of water diversions.
