Our California Water Map, recently updated, is one of our
most popular products. We also offer magazines, documentaries,
posters, layperson guides and more. Our catalog offers a wide
array of resources to help you understand the complex issues of
water in California and the Southwest.
California’s groundwater is a great natural resource and has
contributed to the state becoming the nation’s top agricultural
producer and a leader in high-tech industries. Groundwater is an
asset that is increasingly relied upon by municipalities,
industry and agriculture and it will play an important role in
the future sustainability of California’s overall water supply.
Participants on our Northern California
Tour Oct. 2-4 will get updates on changes planned or
completed at key dams that anchor California’s two major water
delivery projects — Shasta Dam and Oroville Dam.
The tour will visit Shasta Dam, keystone of the federal Central Valley Project,
for a firsthand look at plans to raise the height of the
structure and increase storage capacity, and hear from some who
oppose the expansion. A tour of the Shasta Powerplant and a
houseboat outing on Shasta Lake, already California’s largest
reservoir, are also part of the tour.
The Colorado River Basin’s 20 years
of drought and the dramatic decline in water levels at the
river’s key reservoirs have pressed water managers to adapt to
challenging conditions. But even more extreme — albeit rare —
droughts or floods that could overwhelm water managers may lie
ahead in the Basin as the effects of climate change take hold,
say a group of scientists. They argue that stakeholders who are
preparing to rewrite the operating rules of the river should plan
now for how to handle these so-called “black swan” events so
they’re not blindsided.
Newsom saw SB 1 as a mortal threat to something he’s been
supporting since shortly before he took office: a tentative
truce in California’s longstanding water wars. The truce
revolves around the flow of water in and out of the Delta from
California’s most important river systems, the Sacramento and
The administration of Gov. Gavin Newsom has imposed a de-facto
moratorium on hydraulic fracturing while it studies permitting
procedures for the politically controversial oil
well-completion technique better known as fracking.
There’s a lot to like about the Bay Area’s efforts to prepare
for sea level rise: the collaborative efforts, the detailed
studies and, laudably, the voters who are willing to tax
themselves with an eye to future needs. But if the long-term
threat is as grim as scientific projections indicate, local
experts say the region needs to respond with increased urgency
— an urgency that is at odds with the Bay Area’s often
cumbersome decision-making processes.
Something is amiss on Sherman Island, a whale-shaped swath of
farm and grazing land at the confluence of the Sacramento and
San Joaquin rivers. If you don’t know what ails the place, it
might be hard to pinpoint the problem.
Wetlands are among the most important ecosystems in the world.
They produce high levels of oxygen, filter toxic chemicals out of
water, reduce flooding and erosion, recharge groundwater and provide a diverse
range of recreational opportunities from fishing and hunting to
photography. They also serve as critical habitat for wildlife,
including a large percentage of plants and animals on
California’s endangered species
As part of the historic Colorado River Delta, the Salton Sea
regularly filled and dried for thousands of years due to its
elevation of 237 feet below sea level.
The most recent version of the Salton Sea was formed in 1905 when
the Colorado River broke
through a series of dikes and flooded the seabed for two years,
creating California’s largest inland body of water. The
Salton Sea, which is saltier than the Pacific Ocean, includes 130
miles of shoreline and is larger than Lake Tahoe.
