California’s safe drinking water standards require a multistep
treatment process that includes filtration and disinfection. This
process removes and kills viruses, including coronaviruses such
Twenty years ago, the Colorado River
Basin’s hydrology began tumbling into a historically bad stretch.
The weather turned persistently dry. Water levels in the system’s
anchor reservoirs of Lake Powell and Lake Mead plummeted. A river
system relied upon by nearly 40 million people, farms and
ecosystems across the West was in trouble. And there was no guide
on how to respond.

UC San Diego says it detected traces of the novel coronavirus
in five areas of campus over the weekend after it greatly
expanded its search for the pathogen in wastewater samples
drawn from dozens of buildings.
A new partnership with Pasadena-based Jet Propulsion Laboratory
(NASA JPL) will help state agencies better understand climate
change impacts and identify opportunities to build resilience,
conserve biodiversity and use California’s natural and working
lands to store and remove carbon from the atmosphere.
Wetlands are among the most important ecosystems in the world.
They produce high levels of oxygen, filter toxic chemicals out of
water, sequester carbon, 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.
Drought— an extended period of
limited or no precipitation— is a fact of life in California and
the West, with water resources following boom and-bust patterns.
During California’s most recent drought, from 2012–2016, much of
the state experienced severe drought conditions – significantly
less precipitation and snowpack, reduced streamflow and higher
No portion of the West has been immune to drought during the last
century and drought occurs with much greater frequency in the
West than in any other regions of the country.
