Drought planning
(Mountain Democrat, August 25, 2005)
Editorial. "What would El Dorado County do if there was another
drought like the two years of July 1975 through June 1977? More
importantly, how can the critical water shortage from such dry years
be avoided? That was the subject of a series of study sessions
sponsored by the El Dorado Irrigation District and the El Dorado
County Water Agency."

Urban Water Management Plans (UWMP) are
due to the Department of Water Resources (DWR) by the end of 2005.
Some of the new components include factoring groundwater and
desalination into water supply planning. Rather than being a purely
regulatory exercise, these plans provide a planning basis that can be
used to obtain funding, not only for capital improvement plans (CIPs)
but also for grant funding. Read all about it

Role of Ecosystem Restoration.” The keynote speaker, Mr. Bill Dawson,
Director for Civil Works Planning and Policy for the US Army Corps of

considerations to a developed project like the “extras” added to
sweeten a car sale---that the environmental aspects of a project must

EPA and Army Corps Issue Wetlands
Decision
"Today we are reaffirming and bolstering protections for wetlands,
which are vital for water quality, the health of our streams and
wildlife habitat,” said EPA Administrator Mike Leavitt.
The Environmental Protection Agency (EPA)
and the Army Corps of Engineers (Corps) today reiterated the
Administration’s commitment to the goal of “no net loss” of wetlands
in the United States. EPA and the Corps announced that they would not
issue a new rule on federal regulatory jurisdiction over isolated
wetlands. After soliciting public comment to determine
if further regulatory clarification was needed,
the EPA and the Corps have decided to
preserve the federal government’s authority to protect our wetlands.

California city public works directors
are looking at the renewal of their local permit for storm water
discharge rules. Throughout Southern California the directors are
discovering that these new permits come with higher price tags and
smaller pollutant discharge limits.
The real size of the price tag is only
now becoming apparent. In January 2003, the University of Southern
California issued a study on the Los Angeles Regional Board’s recently
adopted storm water rules, concluding that the equivalent of $305 to
$2,300 per year per household would be required to fund the storm
water programs under the permit. Moreover, the report identified
economic impacts, including a significant loss of jobs within the
region. Although community activists are saying that the
environmental costs and loss of the beach tourism dollars from failing
to comply are even higher, the fact remains that hard dollars are
needed to comply. It will fall upon the cities, and in particular the
inland cities, to develop these hard dollars. In contrast, the
immediate benefit of these programs will be to the coastal environment
and to tourism economies.
The hard dollars needed for the programs
won’t be coming from the strapped budgets of California cities, and
must be raised from new sources of funding. One funding mechanism
will require new fees to be paid by parcel owners, with their
consent. Since 1996 and the passage of Proposition 218, new funding
requires a majority approval of the affected parcel-owners for new
property-related fees.

Global Warming
Impacts on Water Supply--What are the Implications?

Services, and Martin Steinpress,CHG, BC National Service

District, Paul has an extensive background in water supply and

master plans involving water needs assessment, water demand
projections, and preparation of capital improvement programs. Paul

A recent study published
by the University of California, Santa Cruz, and Lawrence Livermore
National Laboratory predicts that, within this century, average
temperatures will rise everywhere, especially in the Sierra Nevada and
Cascade ranges. This rise in temperature, says the study, will cause
significant changes in local weather patterns. Warmer winters will
result in earlier snowmelt runoff, overlapping the storm season. Since
most reservoirs do not have the storage capacity to handle both storm
water and melting snow pack runoff , global warming could have major
implications for flood control and storage of water for summer use.
The university study
came out on the heals of an EPA climate report detailing specific and
far-reaching effects global warming will inflict on the American
environment. The report places most of the blame for recent global
warming on human actions -- mainly the burning of fossil fuels that
send heat-trapping greenhouse gases into the atmosphere. Predicted
effects include the disruption of snow-fed water supplies, more
stifling heat waves and the permanent disappearance of Rocky Mountain
meadows and coastal marshes. It does not, however, propose any major
shift in the administration's policy on greenhouse gases. Instead, it
recommends adapting to inevitable changes. And in March, the Pentagon
released its report:
Pentagon Report Describes Global Warming Dangers,
March 2004

is "plausible and would challenge United States national security in
ways that should be considered immediately," according to a report
commissioned by the Pentagon and obtained by media outlets in February

Predictions
of earlier snowmelt runoff in the two reports are particularly
worrisome to western states where water supplies are already stretched
thin in normal years. Most rivers in the West and all major rivers in
California already have reservoirs whose operation must balance a
myriad of competing demands including evacuation to capture seasonal
floodwaters; releases for electrical power production, recreation, and
in-stream flow requirements; and storage for agricultural and urban
water supplies during summer and drought periods. The electricity
crisis of the early 2002s has increased pressures to maximize
hydropower production, particularly during peak summer demand periods.
Meanwhile, endangered species and riparian habitat concerns have
increased the need to release water for environmental benefits,
including maintaining the water quantity and water quality in
California's Sacramento-San Joaquin Bay and Delta. Finally, rapid
population growth is increasing urban water demands at a time when
construction of new dams is politically infeasible. The prospect of
earlier snowmelt and more erratic runoff patterns threatens to further
tax the already overburdened water infrastructure.
In our
opinion, the reports'
conclusions should spur further efforts by forward-thinking water
suppliers in the West to develop projects that facilitate
conjunctive use, which is the integrated management of both
surface water and groundwater. With increasingly capricious surface
water supplies, those water agencies that develop the ability to
optimally use a mix of surface and groundwater will be best prepared
for the threat of drought as well as the related effects of global
warming.

Conjunctive
use often requires additional infrastructure and /or regional
cooperative partnerships to facilitate the use of surface water during
seasonal wet periods and above average precipitation years, with the
ability to draw on groundwater supplies during seasonal dry periods
and drought cycles. Groundwater basins can thus provide the increased
water storage capacity that water agencies can utilize to mitigate the
effects of global warming. However, most groundwater basins are
heavily used now and many are already in overdraft, a situation in
which groundwater pumping exceeds natural recharge and long-term water
levels decline. Most groundwater basins therefore can only be relied
upon to provide greater drought insurance if measures are taken to
artificially increase groundwater recharge.
Artificial
recharge can be accomplished during periods of water surpluses by
either active recharge (through surface recharge basins or
injection/extraction wells, which is also known as aquifer storage and
recovery) or by the delivery and use of surface water by users who
would otherwise pump groundwater (known as in-lieu recharge).
Depending on the individual location, the sources of water for
groundwater recharge may include not only storm water and spring
runoff from snowmelt, but recycled municipal or industrial wastewater
as well (with proper treatment to address water quality issues).
