Located on the west side of the San Joaquin Valley in the Coast
Range foothills, San Luis Dam and Reservoir are used by the state
and federal governments to store water diverted from the Delta.
It is the largest offstream reservoir in the United States.
The San Luis Reservoir is a key water facility serving both the
State Water Project and the federal Central Valley Project. It
can hold 2 million acre-feet of water and is jointly owned by the
federal Bureau of Reclamation and California’s Department of
Water Resources. The state’s share of the San Luis
Reservoir water is 55 percent.
The Bureau of Reclamation and the California Department of
Water Resources are conducting exploratory work, including
clearing, excavation and controlled blasting of rock material
in the Basalt Hill area near B.F. Sisk Dam, located between Los
Banos and Gilroy, between 6 a.m. to 8 p.m. during April and
May. The exploratory findings on Reclamation lands will help
identify size and quality of granular material for the planned
Safety of Dams Modification project.
The James Irrigation District in western Fresno County has sued
the Westlands Water District over its plan to let farmers pump
salty groundwater into the Mendota Pool in exchange for water
from the San Luis Reservoir.
The preferred alternative to address seismic safety concerns at
the structure, commonly known as San Luis Dam, involves raising
the crest of the dam by 12 feet, adding shear keys to prevent
slippage and construction of downstream berms to strengthen the
structure… Work on the project is expected to begin in August
2021
President Donald Trump’s administration rolled out an
aggressive plan Tuesday to ship more water from the Delta to
farmers in the San Joaquin Valley, a move that’s certain to
trigger lawsuits by environmentalists concerned about
endangered fish species.
The Bureau of Reclamation and Valley Water released draft
environmental documents for public comment on the San Luis Low
Point Improvement Project, which addresses water delivery
interruptions and proposes to maintain reliable and
cost-effective water supply.
The Department of Water Resources (DWR) urged people to avoid
physical contact with the water at San Luis Reservoir in Merced
County until further notice and avoid eating fish from the lake
due to the presence of blue-green algae. DWR increased the
advisory from warning to danger after detecting an increased
amount of microcystins.
Venture through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
April 3, 2020 Update: This tour was originally scheduled for April 22-24 but has been postponed due to developments with COVID-19. If any tour attendee already registered cannot make the new dates, substitutions can be made. We can also provide refunds up until three weeks prior to the Sept. 30 start of the tour.

The San Joaquin Valley, known as the
nation’s breadbasket, grows a cornucopia of fruits, nuts and
other agricultural products.
During our three-day Central Valley Tour April
3-5, you will meet farmers who will explain how they prepare
the fields, irrigate their crops and harvest the produce that
helps feed the nation and beyond. We also will drive through
hundreds of miles of farmland and visit the rivers, dams,
reservoirs and groundwater wells that provide the water.
A coalition of environmental groups has called on California
members of Congress to prioritize the San Luis (B.F. Sisk)
Dam seismic remediation over federal funding for new California
dams. San Luis Dam is in a very seismically active area.
Independently reviewed risk assessments for Reclamation have
shown that a large earthquake could lead to crest settlement
and overtopping of the dam, which would result in large
uncontrolled releases and likely dam failure.
This tour ventured through California’s Central
Valley, known as the nation’s breadbasket thanks to an
imported supply of surface water and local groundwater. Covering
about 20,000 square miles through the heart of the state,
the valley provides 25 percent of the nation’s food, including 40
percent of all fruits, nuts and vegetables consumed throughout
the country.

Get a unique view of the San Joaquin Valley’s key dams and
reservoirs that store and transport water on our March Central
Valley Tour.
Our Central Valley
Tour, March 14-16, offers a broad view of water issues
in the San Joaquin Valley. In addition to the farms, orchards,
critical habitat for threatened bird populations, flood bypasses
and a national wildlife refuge, we visit some of California’s
major water infrastructure projects.

Last summer it was a jarring symbol of California’s historic
five-year drought. San Luis Reservoir — the vast lake along
Highway 152 between Gilroy and Los Banos, the state’s
fifth-largest reservoir and a key link in the water supply for
millions of people and thousands of acres of Central Valley
farmland — was just 10 percent full.
San Luis Reservoir west of Los Banos is on its way to filling
for the first time since 2011 as rain and snow bring the state
additional relief from a punishing drought. Statewide, a series
of storms over the past two weeks have allowed water managers
to fill major reservoirs to above-normal levels for this time
of year.
Robert Haskins walked across a vast expanse of cracked mud,
littered with old beer bottles and millions of tiny clam
shells, that in most Augusts would be 50 feet underwater. But
the San Luis Reservoir, the vast inland sea along Highway 152
that is a key part of Silicon Valley’s water supply, is only 10
percent full, its lowest level in 27 years.
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.
This 3-day, 2-night tour travels the length of the San Joaquin
Valley, giving participants a clear understanding of the State
Water Project and Central Valley Project.
30-minute DVD that traces the history of the U.S. Bureau of
Reclamation and its role in the development of the West. Includes
extensive historic footage of farming and the construction of
dams and other water projects, and discusses historic and modern
day issues.
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 history of the project, the guide
describes the various CVP facilities, CVP operations, the
benefits the CVP brought to the state, and the CVP Improvement
Act (CVPIA).
This 3-day, 2-night tour travels the length of the San Joaquin

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.
