First Snow Survey of 2014 Shows Dry
Conditions California Braces for Possible
Third Dry Year
SACRAMENTO – As California’s dry weather pushes into
the new year, the Department of Water Resources (DWR) today announced that its
first snow survey of the winter found more bare ground than snow.
Manual and electronic readings record
the snowpack’s statewide water content at about 20 percent of average for this
time of year. That is a mere 7 percent of the average April 1 measurement, when
the snowpack normally is at its peak before melting into streams and reservoirs
to provide a third of the water used by California’s cities and farms.
“While we hope conditions improve, we
are fully mobilized to streamline water transfers and take every action
possible to ease the effects of dry weather on farms, homes and businesses as
we face a possible third consecutive dry year,” said DWR Director Mark Cowin.
“And every Californian can help by making water conservation a daily habit.”
The last time California’s statewide
snowpack was this dry was in 2012 when it also was 20 percent of the historical
average. The readings today and in 2012 are the driest on record.
Today’s electronic readings indicate
that water content in the northern mountains is 11 percent of normal for the
date and 4 percent of the April 1 average. Electronic readings in the central
Sierra show 21 percent of normal for the date and 8 percent of the April 1
average. The numbers for the southern Sierra are 30 percent of average for the
date and 10 percent of the April 1 average.
In addition to the sparse snowpack, many
areas of California ended calendar year 2013 with the lowest rainfall amounts
on record. Normally one of California’s wettest spots with an average annual
rainfall of nearly 100 inches, Gasquet Ranger Station in Del Norte County ended
the year with only 43.46 inches. Sacramento, which normally gets about 18
inches, ended up with 5.74 inches of precipitation. And downtown Los Angeles,
which since 1906 has averaged 14.74 inches of rain, ended the year with 3.4
inches, beating the previous low of 4.08 inches recorded in 1953.
DWR and cooperating agencies conduct
manual snow surveys around the first of the month from January to May. The
manual measurements supplement and check the accuracy of real-time electronic
Results of today’s manual readings by
DWR off Highway 50 near Echo Summit are as follows:
The average January 1 snowpack water
content at Phillips Station is about 12 inches and the April 1 average 27.6 inches.
Phillps had its lowest water content reading of 0.1 inch in 2012, in a snow
depth of only 0.6 inches. On January 2 last year (2013) at Phillips there were
12.1 inches of water in 48.8 inches of snow. Besides 2012, the driest years at
Phillips were 1987 (0.9 inches of snowpack water content), 1981 (2 inches),
1976 (2.7 inches) and 2000 (3 inches).
Records at Phillips go back 50 years.
DWR currently estimates it will be able
to deliver only 5 percent of the slightly more than 4 million acre-feet of State
Water Project (SWP) water requested for calendar year 2014 by the 29 public
agencies that collectively supply more than 25 million Californians and nearly
a million acres of irrigated farmland. It is hoped the initial 5 percent
delivery estimate – tied with calendar year 2010 for the lowest initial
allocation ever -- will increase as winter storms develop. The initial 2010
delivery estimate, made on the heels of the 2007-2009 drought, was eventually
increased to 50 percent as winter storms developed.
The final SWP allocation for calendar
year 2013 was 35 percent of the slightly more than 4 million acre-feet
requested. In 2012, the final allocation was 65 percent. It was 80 percent in
2011, up dramatically from an initial allocation of 25 percent. The final
allocation was 50 percent in 2010, 40 percent in 2009, 35 percent in 2008, and
60 percent in 2007. The last 100 percent allocation – difficult to achieve even
in wet years because of Delta pumping restrictions to protect threatened and
endangered fish – was in 2006.
DWR weather watchers note that it’s
early in the season and this winter could still turn out wet. The concern,
however, is that irrigation-dependent San Joaquin Valley farms and some other
areas will be hard hit if we have another dry year without the cushion of
reservoir storage that we had in calendar year 2013 due to the storms in late
2012 before California began sliding toward drought.
Lake Oroville in Butte County, the State
Water Project’s (SWP) principal reservoir, today is at only 36 percent of its
3.5 million acre-foot capacity (57 percent of its historical average for the
date). Shasta Lake north of Redding, California’s and the federal Central
Valley Project’s (CVP) largest reservoir, is at 37 percent of its 4.5 million
acre- foot capacity (57 percent of average for the date).
San Luis Reservoir, a critical
south-of-Delta reservoir for both the SWP and CVP, is a mere 30 percent of its
2 million acre-foot capacity (43 percent of average for the date) due both to
dry weather and Delta pumping restrictions last winter to protect salmon and
Delta smelt. Delta water is pumped into the off-stream reservoir in winter and
early spring for summer use in the Bay Area, San Joaquin Valley, Central Coast
and Southern California.
The continuing dry weather prompted
Director Cowin on December 13 to mobilize DWR’s drought management team “to
offset potentially devastating impacts to citizen health, well-being and our
Governor Edmund G. Brown Jr. has united
DWR and other agencies in an Interagency Drought Task Force.
DWR and other agencies will streamline
transfers of water from areas of relative abundance to areas of critical need,
monitor water supply impacts in small rural communities whose groundwater
sources are stressed by prolonged dry conditions, and take other steps to
mitigate the effects of dry weather.
