Stretching along the eastern edge of the state, the Sierra Nevada
region incorporates more than 25 percent of California’s land
area and forms one of the world’s most diverse watersheds.
It features granite cliffs, lush forests and alpine meadows on
the westside, and stark desert landscapes at the base of the
eastside. Wildlife includes bighorn sheep, mule deer, black bear
and mountain lions, hawks, eagles, and trout.
The majority of total annual precipitation – in the form of rain
and snow – falls in the Sierra Nevada. Snowmelt from the Sierra
provides water for irrigation for farms that produce half of the
nation’s fruit, nuts and vegetables, and also is a vital source
for dairies, which have made California the largest milk producer
in the country.
In addition, Sierra snowmelt provides drinking water to Sierra
Nevada residents and a portion of drinking water to 23 million
people living in cities stretching from the Bay Area to Southern
Lawsuits from environmental groups are snagging badly needed
efforts to log forests in California’s fire-prone Sierra Nevada
mountains, lawmakers and witnesses told a House of
Representatives subcommittee Thursday.
When Andy Wirth became the CEO of Squaw Valley Ski Resort in
November 2010, he did so amid a precipitation-laden winter that
saw enormous snow loads give skiers at Lake Tahoe plenty of
coveted powder days.
The peak of the Lake Tahoe wildflower season is typically
somewhere around the middle of July, but, with remaining snow
melting away and water in scarce supply, area blooms are off to
an early start and may not last long.
South Tahoe Public Utilities District’s (STPUD) hope to have
mandatory water reductions reduced drowned on April 17 when the
State Water Resources Control Board released revised numbers of
California’s water districts.
The fourth year of the devastating drought that has dried up
wells, forced mandatory rationing and jeopardized California
crops has also put a burden on backcountry skiers in search of
their powdery fix.
The Sierra snowpack is a ghastly one-fifth the size of the
smallest one ever recorded in the mountain range, state leaders
said Wednesday as California’s storm season ended in
disappointment for the fourth straight year. … Gov. Jerry
Brown, who watched a snow measurement Wednesday at Lake Tahoe,
announced the state’s first mandatory water reductions, aiming
at cutting water use by 25%.
Standing in a dry brown meadow that typically would be buried
in snow this time of year, Gov. Jerry Brown on Wednesday
ordered the first mandatory water cutbacks in California
history, a directive that will affect cities and towns
We are officially in uncharted territory. The Sierra Nevada
snowpack, which typically supplies nearly a third of
California’s water, is showing the lowest water content on
record: 6 percent of the long-term average for April 1.
The water frozen in snow throughout the Sierra Nevada is 8% of
average — less than a third the size of the smallest on record.
On Wednesday when this disappointing wet season ends, the
headlines will be the next alarm bell in the state’s damaging,
With the state entering its fourth year of drought, some
conservationists are looking at thinning Sierra forests to
increase the amount of water that flows into area rivers. …
On Friday, the Association of California Water Agencies also
released its own report that calls for better headwater and
forest management – and for better collaboration among federal,
state and other agencies, and other stakeholders.
The Lake Don Pedro community is operating in emergency
mode. For the last several weeks, work crews have drilled
well after well, hoping to find groundwater. … Lake
McClure depends entirely on rain and snow runoff from the
Merced River watershed.
Levels at Sierra reservoirs that supply water for 1.3 million
East Bay customers are as low as they’ve been in nearly 40
years, and it could take a miracle to make them better before
the onset of the long dry season, officials were told Tuesday.
With a fourth year of drought looming, state and federal
agencies have launched an ambitious partnership to improve the
Sierra’s ability to store and filter water, as well as reduce
fire risks, by restoring its forests. Called the Sierra Nevada
Watershed Improvement Program …
Had it not been for a couple of days of snowfall during the
weekend, the ground would have been bare, Frank Gehrke of the
Department of Water Resources said Tuesday during a snow survey
at Philips Station near Sierra-At-Tahoe Road.
Snow levels in the Sierra Nevada are at or below what they were
during the driest years in California’s recorded history,
surveyors said Tuesday, dashing hopes that last weekend’s storm
would begin to pull the state out of its increasingly frightful
California received a double dose of bad drought news on
Tuesday, with state officials saying the snowpack in the Sierra
Nevada is far below normal and that residents again aren’t
coming close to meeting Gov. Jerry Brown’s call for a 20
percent cut in water use.
Water consumption statewide declined just 8.8 percent in
January compared with the same month of 2013 – far below the
state’s goal of 20 percent – according to data presented to the
State Water Resources Control Board on Tuesday.
A storm system heading to Northern California may bring only a
fraction of an inch of rain to the Bay Area, but skiers and
snowboarders turned desperate by the drought are stoked after
learning that nearly a foot of fresh powder could fall in some
parts of the Sierra.
This is the fourth lousy winter season in a row for the ski
industry, and it has been economically devastating for the
area. Some of the smaller resorts are barely hanging on, while
larger players are carving out new ways to turn a profit.
While residents’ efforts to conserve water are helping,
officials say locals must continue such practices as a
multi-year drought grips California and other western states
with no immediate relief in sight.
I [Kevin MacMillan] moved to the Tahoe in July 2007, meaning
this is my eighth winter* here. “Winter” has an asterisk next
to it because even I know, with my meager experience here, that
what we’re currently enduring is (hopefully?) some sort of
Because of the lack of snow depth, the U.S. Forest Service
has asked snowmobile users in the Lake Tahoe Basin to
avoid bare dirt and patchy snow, and not to ride across streams
or over small trees and brush.
Today, snow sensors scattered through the Sierra, satellite
imagery and aerial flybys augment the 106-year-old “manual
survey.” The technology helps to provide a clearer update of
California’s water conditions that water agencies depend on to
perform the increasingly crucial job of managing our
diminishing water supply for the rest of the year.
Traditionally California’s wettest month, January’s meager
rainfall has produced a miniscule improvement in the crucial
winter snowpack in the Sierra Nevada that historically provides
about 30 percent of the state’s water needs.
The latest survey of California’s mountain snowpack on Thursday
brought the bad news slamming home: This month will rank as the
driest January in state history at many locations, virtually
assuring a fourth straight year of drought. On Thursday, the
statewide snowpack was 25 percent of normal for the date.
As California caps what may be its driest January on record,
Frank Gehrke will lead a bevy of surveyors on Thursday to a
predetermined spot on Echo Summit in an exercise that has

temporarily closed due to a lack of snow, and forecasters say
the lingering drought should persist or get worse in the months
ahead across most of California and Nevada.
The 862-acre mountain that rises to 8,200 feet — a relatively
small site by California standards — was the latest in two days
to ground operations as January temperatures climb to
near-record highs and weeks pass without wet weather.
Meteorologists are currently watching a weak El Niño event
simmering in the Pacific Ocean, waiting and wondering if it
will ever get strong enough to possibly produce a healthy
Sierra snowpack to help improve drought conditions.
Snow levels that didn’t quite measure up turned a snowshoe
party in the Sierra into an exercise in hand-wringing on
Tuesday as it became clear that recent storms have done little
to end California’s historic drought.
Measurements of Sierra Nevada snowpack on Tuesday [Dec. 30]
showed more snow than surveyors recorded a year ago. But state
water officials said it was far from enough to signal a
potential end to California’s continuing drought.
Forty-five years ago, in December 1969, President Richard Nixon
signed a unique Bi-State Compact approving California and
Nevada’s plan to create the Tahoe Regional Planning Agency. It
was the first such undertaking of its kind, uniting two states,
six local jurisdictions, and the federal government in a shared
mission to protect Lake Tahoe’s sensitive environment from
Buoyed by big December storms, the snowpack is about 150
percent of where it usually is at this time in the year,
according to the California Department of Water Resources. And
more may be on the way, weather forecasters said.
With a string of storms pummeling the Sierra Nevada, Mother
Nature gifted a December dump of powder just in time for the
holidays. That means sledding, building snowmen, carving snow
angels and snowball fights.

upcoming storm and its potential for producing a powder day. A
friend, a little more grizzled in his Sierra Nevada lifestyle,
promptly shut me down with a “I’ll believe it when I see it.”
Complete recovery from the drought gripping California and
other western states is not likely this winter, according to a
recent forecast. … Tahoe’s drought is predicted to persist,
according to a NOAA drought outlook map for Oct. 16, 2014,

Visitor Center, prompting a warning from the U.S. Forest
Service. The annual Kokanee salmon run at the visitor center
has become a popular tourist spectacle …”
Rangers at Yosemite National Park are in a constant battle to
keep wild black bears — with their ultra-keen noses and
powerful paws and jaws — far away from humans. … The
instances of bears raiding campgrounds and parking lots for
human food are up by 35 percent from Jan. 1 to Oct. 19 compared
to the same period last year — the second such increase during
the state’s three consecutive dry years.
Lingering drought has helped push Lake Tahoe’s water level
below its natural rim for the first time in five years, cutting
off flows into the Truckee River, which has been reduced to a
shallow stream as it meanders down the Sierra through Reno.
On a local level, the Truckee Donner Land Trust has executed
roughly 42 purchases — some funded with public money — overall
varying in size from about 300 acres to more than 7,000 acres
of open space since 1990, when a small group of hikers bought a
160-acre parcel in the Coldstream Valley near Donner Lake.
A coalition of advocacy groups on Monday challenged the
government’s denial of federal protections for the snow-loving
wolverine, arguing in a lawsuit that officials disregarded
evidence a warming climate will eliminate denning areas for the
so-called “mountain devil.”
Rugged and isolated, the Rubicon River Valley on the border of
El Dorado and Placer counties was for many years an idyll of
old growth trees and icy swimming holes. … Experts now worry
that the devastation and the extreme temperatures of the fire,
which scorched much of the soil and reduced its ability to hold
together and absorb runoff, could lead to floods and mudslides
when winter storms arrive.
The Sierra Nevada water year for 2014 ended on Sept. 30 and the
snowfall and precipitation totals aren’t pretty. The 194.5
inches of snowfall measured last season at the Central Sierra
Snow Lab tied with 1924 as third least snowiest since 1879,
well under the 409 inch seasonal average.
