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.
Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed

The landmark Sustainable Groundwater Management Act, or SGMA,
requires some of the state’s thirstiest areas form local
“Groundwater Sustainability Agencies” and submit long-term
plans by Jan. 31 for keeping aquifers healthy. Together, those
plans will add up to a big reveal, as groundwater managers
finally disclose how badly they believe their aquifers are
California increased its efforts Friday to keep the federal
government from allowing oil and gas drilling on more than 1
million acres of public land, suing to block the Trump

More rain and snow area headed to Northern California on

for what’s been a relatively dry January. … The Department of
Water Resources’ precipitation index was at 63 percent of
normal for the Valley and Sierra. The Sierra snowpack is 82
percent of normal.
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.
