Shasta Dam creates the largest storage reservoir in the state,
Shasta Lake. In years of normal precipitation, the Shasta system
stores and distributes about 20 percent of the state’s developed
water — about 7 million acre-feet —through its massive system of
reservoirs and canals.
Located 12 miles north of Redding, Shasta traps the cold waters
of the Pit and McCloud rivers and the headwaters of the
Sacramento River behind its 602-foot curved, concrete face.
Water is transported 450 miles from Lake Shasta in Northern
California to the San Joaquin Valley. Along the way, the
Central Valley Project has long-term agreements with more than
250 contractors in 29 of California’s total 58 counties.
Higher-than-normal rainfall during the past month has
dramatically changed Lake Shasta, with the water level of
California’s largest reservoir rising 60 feet since the end of
December. Gone are vast areas of shoreline that became parking
lots and campgrounds as the lake dried up and the water level
dropped during the past several years of low rainfall in the
North State. By Monday, the lake was 56% full, an improvement
over the 34% recorded Jan. 3. The California Department of
Water Resources said the lake was 87% of normal as of Monday,
compared to the 57% of normal at the beginning of January.
The past weeks following our recent large storms have been
awash in misinformation and hypocrisy about operating and
permitting water infrastructure in California. Even those who
closely follow the news about California water are likely
unaware that the data shows that more than half of the runoff
from the storms in early January was captured and stored in the
Central Valley. Or that the loudest voices criticizing
environmental protections for our rivers and fisheries during
the storms – which are requirements of the Trump
Administration’s 2019 biological opinions – are the very same
voices demanding that legislators and the courts keep those
biological opinions in place.
Climate change including multi-year droughts, extreme flooding,
and extreme weather swings negatively impact California.
Aridification of our ecosystem, and multi-year droughts are
damaging to cold-water-dependent species such as Chinook
salmon. Such is the case with the current drought we are
experiencing, which has exacerbated the stressors impacting the
Sacramento River’s threatened spring-run Chinook salmon and
endangered winter-run Chinook salmon. These stressors include
the inability to maintain suitable water temperatures,
increased predation, and diminished habitat quantity and
quality. Coupled with drought impacts in freshwater is
the recently discovered thiamine deficiency in adult Chinook
returning from the ocean which impacts the health of their
offspring.
California’s water supply has hit a new milestone for the year
in the wake of three weeks of wet weather. Water levels at two
of the state’s largest reservoirs are now at their highest
point in 2.5 years, Chief Meteorologist Mark Finan said.
… Lake Shasta and Oroville have both added more than 1
million acre-feet of water in the past month and the levels
continue to rise. Inflow rates into those reservoirs have
decreased considerably, which is to be expected during periods
of dry weather. As of Tuesday, Lake Shasta is at 55% of
its total capacity and Lake Oroville is at 62% of capacity.
Last summer, Lake Shasta peaked at about 40% of its total
capacity.
Without a doubt, weeks of rain and snow since late December are
absolutely helping with California’s water supply. But how much
help exactly is a question many have been asking. KCRA 3 Chief
Meteorologist Mark Finan goes over where water reservoirs in
Northern California stand. Spoiler alert: It’s a lot of good
news. … Shasta is the state’s biggest reservoir, able to
hold 4 1/2 million acre-feet of water. As of Jan. 17, it stands
at 52% capacity compared to 34% a year ago. … As of Jan.
17, [Folsom] is at 54% capacity compared to 56% a year
ago. The thing to understand about Folsom’s capacity right now
is that it is already in flood control mode, meaning that water
is already being released to balance out the reservoir because
there is still plenty of the year to go. And then there’s the
snowpack to consider when it melts.
No, California’s drought is not over, not by a long shot. But
weeks of near-constant rainfall have improved the situation
considerably, according to the U.S. Drought Monitor’s weekly
report released Thursday. The map updated Thursday shows most
of the state in moderate or severe drought after about seven
atmospheric river storms swept through the state since
Christmas Day. Only a small portion in the extreme northeastern
portion of the state remains in extreme drought, while the
northwestern corner of the state and much of Imperial County
dropped to the lowest level of drought, termed abnormally dry.
The Sacramento and Central valleys, which were in extreme and
extraordinary drought just three months ago, have seen
conditions improve to severe.
California is on the cusp of an opportunity squandered. The
atmospheric river and “cyclone bomb” projections suggest well
over 10 inches of rain and as many feet of snow could fall on
the state within a week’s time. What is California doing,
amidst the governor’s declared state of emergency, to squirrel
away as much of that runoff and flood water as the state’s
infrastructure will allow? With all this known water
coming into the system, why isn’t the State of California
moving as much water as can physically be moved into San Luis
Reservoir? Roughly half of the reservoir’s water at full pool
is owned by the federal government, with the other half
controlled by the state. A full San Luis Reservoir means
more water for Central Valley farmers and more available water
for the State Water Project. -Written by Todd Fitchette.
This tour explored the Sacramento River and its tributaries
through a scenic landscape while learning about the issues
associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of
California’s water and feed into two major projects: the State
Water Project and the federal Central Valley Project.

The deadliest and most destructive
wildfire in California history had a severe impact on the water
system in the town of Paradise. Participants on our Oct. 2-4
Northern California
Tour will hear from Kevin Phillips, general manager of
Paradise Irrigation District, on the scope of the damages, the
obstacles to recovery and the future of the water district.
The Camp Fire destroyed 90 percent of the structures in Paradise,
and 90 percent of the irrigation district’s ratepayer base. The
fire did not destroy the irrigation district’s water storage or
treatment facilities, but it did melt plastic pipes, releasing
contaminants into parts of the system and prompting do-not-drink
advisories to water customers.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
Bruce Babbitt, the former Arizona
governor and secretary of the Interior, has been a thoughtful,
provocative and sometimes forceful voice in some of the most
high-profile water conflicts over the last 40 years, including
groundwater management in Arizona and the reduction of
California’s take of the Colorado River. In 2016, former
California Gov. Jerry Brown named Babbitt as a special adviser to
work on matters relating to the Sacramento-San Joaquin Delta and
the Delta tunnels plan.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:

The Colorado River Basin is more
than likely headed to unprecedented shortage in 2020 that could
force supply cuts to some states, but work is “furiously”
underway to reduce the risk and avert a crisis, Bureau of
Reclamation Commissioner Brenda Burman told an audience of
California water industry people.
During a keynote address at the Water Education Foundation’s
Sept. 20 Water Summit in Sacramento, Burman said there is
opportunity for Colorado River Basin states to control their
destiny, but acknowledged that in water, there are no guarantees
that agreement can be reached.

and the steps being taken to prepare for another dry year should
it arrive.
This 25-minute documentary-style DVD, developed in partnership
with the California Department of Water Resources, provides an
excellent overview of climate change and how it is already
affecting California. The DVD also explains what scientists
anticipate in the future related to sea level rise and
precipitation/runoff changes and explores the efforts that are
underway to plan and adapt to climate.
Water as a renewable resource is depicted in this 18×24 inch
poster. Water is renewed again and again by the natural
hydrologic cycle where water evaporates, transpires from plants,
rises to form clouds, and returns to the earth as precipitation.
Excellent for elementary school classroom use.
The 24-page Layperson’s Guide to the Central Valley Project
explores the history and development of the federal Central
Valley Project (CVP), California’s largest surface water delivery
system. In addition to the project’s history, the guide describes
the various CVP facilities, CVP operations, the benefits the CVP
brought to the state and the CVP Improvement Act (CVPIA).
The 24-page Layperson’s Guide to the Delta explores the competing
uses and demands on California’s Sacramento-San Joaquin Delta.
Included in the guide are sections on the history of the Delta,
its role in the state’s water system, and its many complex issues
with sections on water quality, levees, salinity and agricultural
drainage, fish and wildlife, and water distribution.
A new look for our most popular product! And it’s the perfect

Our 24×36 inch California Water Map is widely known for being the
definitive poster that shows the integral role water plays in the
state. On this updated version, it is easier to see California’s
natural waterways and man-made reservoirs and aqueducts
– including federally, state and locally funded
projects – the wild and scenic rivers system, and
natural lakes. The map features beautiful photos of
California’s natural environment, rivers, water projects,
wildlife, and urban and agricultural uses and the
text focuses on key issues: water supply, water use, water
projects, the Delta, wild and scenic rivers and the Colorado
River.
Shasta Dam forms California’s
largest storage reservoir, Shasta Lake, which can hold about 4.5
million acre-feet.
As the keystone of the federal Central Valley Project,
Shasta stands among the world’s largest dams. Construction on the dam began in 1938
and was completed in 1945, with flood control as the highest
priority.
