“RECORD DROUGHT SURE TO BRING CHANGES”
There is no longer any doubt about it:
Even if California gets a bit of rain and snow over the next few weeks – and
there is very little in forecasts for most of the state through Feb. 1 – we are
in the midst of the worst drought since the mid-1970s.
One good measure of this may be
the levels of water in California reservoirs – a total of just under 7.7
million acre feet as of Jan. 5, compared with the typical average storage of
about 12 million acre feet at this time of year. One acre foot represents about
what a typical suburban family uses in a year. So California has only about 64
percent of its normal water supply on hand, one reason why Central Valley farms
have been told to expect little flow from either the state Water Project or the
federal Central Valley Project this year.
Even worse, snow levels in the Sierra Nevada
Mountains, source of most California water, are only about 20 percent of
normal, providing little hope for refilling reservoirs as they are drawn down
further, short of a spring deluge a la what the state experienced in 1978.
It shapes up as an unmitigated
disaster, one that some call as catastrophic as a major earthquake. This is a
bigger problem than any wildfire, because it has the potential to cause
multiple massive blazes. Some analyses indicate the ongoing drought was one
major reason the Rim Fire near Yosemite National Park burned so widely last
summer. The state had gotten a record-low 4.58 inches of precipitation from
January to June of last year, and then a major July heat wave added to
tinderbox conditions sustaining that wildfire, the 14th most
damaging in United States history.
So far, this drought has produced no
major changes in state policy and practices, although some cities are already
telling restaurants to serve water only on request, a 1970s-era tactic. But if
past is prologue, as historians often tell us, we can count on bigger changes.
Here’s a little bit of disaster
history: The Field Act, passed on the heels of the Long Beach Earthquake of
1933, changed forever the way schools all over California are constructed.
After the 1971 San Fernando quake severely damaged the Olive View Medical
Center, building standards changed radically for hospitals and nursing homes.
The drought of 1975-77 produced major water conservation changes, among them
wide government distribution of low-flow toilets. These now are standard in new
homes.
What might result from today’s
drought, which saw California get less rain- and snowfall in 2013 than in any
year since record-keeping began? Some politicians hope it will further the
cause of Gov. Jerry Brown’s $25 billion “peripheral tunnels” project, which
probably wouldn’t raise the amounts of water flowing south from the Delta of
the Sacramento and San Joaquin rivers, but could keep the flow steadier, thus
smoothing out supplies for farms and homes in years like the last two.
The problem with this is that not even
drought can change the high cost of that project. But strict water conservation
measures that may come later this year could produce some votes for a $10
billion-plus water bond in November’s election, no sure thing to pass even
under these conditions.
Most likely right now appears to be a
much tougher set of rules regulating how much water farmers can draw from
underground aquifers. Brown hinted strongly at this in his early-January preliminary
budget. There are currently few such restrictions, and in dry years, farmers
who have wells pump more water than normal.
The preponderance of drier-than-usual
years in the decade before conditions reached today’s point of actual drought
caused more such pumping than usual, although no one can quantify it. One
result has been land subsidence of as much as one foot per year in some areas.
Driving some Central Valley highways today, motorists can see instruments and
wellheads that once were on the surface perched 10 or more feet in the air.
Subsidence, in turn, can lead to
problems moving surface water in canals, something water agencies cannot
long tolerate. Which makes it wise to expect regulation of ground water
pumping, among other new drought-spurred actions.
