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.
The spring waters that emerge from the volcanic rocks of
northern California’s Cascade Range are of critical importance
for water security for both fish and people, yet relatively
little is known about them and how they have been affected by
recent drought and other climate change impacts. In 2023,
CalTrout and our partners embarked on a three-year study to
provide a scientifically based toolset to better understand,
manage, and advance the protection of the cold, clean spring
waters in the Upper Sacramento Basin. Building on our
past efforts to assess baseline conditions of springs in the
Mount Shasta region, this study will define and quantify source
areas and flows, assess ecosystem sensitivity to climate
change, and determine how these systems support the diverse
life history of wild cold-water fish. Study locations include
the spring-fed streams above Shasta Reservoir: the McCloud,
Upper Sacramento, Rising, and Fall rivers, Hat Creek, and
Burney Creek, which feeds the iconic Burney
Falls.
The Medicine Lake Highlands complex of public lands, some 30
miles northeast of Mt. Shasta in California’s Cascade region,
is a truly remarkable place. … This area has been
called Sáttítla for time immemorial by the Pit River
Tribe. It is remote and hardly a blip on most people’s radar.
Yet it is on the radar of resource developers. The Pit River
Tribe has been fighting for three decades to safeguard this
landscape and the waters, cultural values and habitats it
provides from proposed development. Last November, the
Tribe launched a new initiative to permanently protect the
Sáttítla region as a national monument. Trout Unlimited,
Backcountry Hunters and Anglers and other conservation-oriented
angling and hunting groups are supporting this campaign.
California’s scorching July heat not only
shattered temperature records, it also removed billions of
gallons of water from the state’s largest reservoirs. From July
1-18, about 4.1 billion gallons of water evaporated from
California’s biggest reservoir, Shasta Lake. This loss
highlights challenges water managers face not just this summer,
but in a hotter, drier future with a thirstier
atmosphere. “If we have less coming in and more going out,
we’re going to be struggling to manage the system moving
forward if there’s more demand,” said Christopher Pearson, an
associate research hydrologist with the Desert Research
Institute. “The system gets out of whack, just like your
checkbook does.”
Once abundant, Chinook have been devastated by habitat loss,
water diversions from the rivers where they spawn and drought.
They are trending toward extinction. And while recovery is a
possibility, it will be an upstream push. The salmon need
improved spawning grounds and more floodplain nursery
habitat.They also need more cold water. And in 2023 and 2024,
both exceptionally wet years, they got it—until, that is, they
didn’t. Water temperatures in the middle Sacramento River
soared to lethal levels this spring, exceeding basic
environmental objectives and threatening salmon born last
summer and fall. With no agency taking firm ownership of the
problem, the mishap raises the question of who’s at the wheel
in managing the state’s reservoirs and rivers for fish and
who’s to be held accountable if salmon disappear.
The continued wet weather in the Northstate has left quite an
impact at Shasta Lake. California’s largest reservoir rose a
foot from Thursday to Friday, and 5 feet from January 26 to
February 2. Currently, Shasta Lake sits at 1,035 feet, roughly
30 feet from capacity. That’s an increase of 47 feet from this
date last year. … Overall, the weather station at Shasta
Dam has reported 36.56 inches of rain since the water year
began on October 1.

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.

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.

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.
