The 32-page Layperson’s Guide to the Colorado River covers the
history of the river’s development; negotiations over division
of its water; the items that comprise the Law of the River; and
a chronology of significant Colorado River events.
Natalie van Doorn, a research ecologist with the U.S. Forest
Service, said that many of the trees commonly planted in urban
areas in California are temperate species that require a lot of
water to survive in hot and dry conditions. … Across the
U.S., metropolitan areas may lose an average of 6 percent of
their tree species as warming trends
continue. … Alison Berry, a professor of plant
sciences at the University of California-Davis, said that
drought stress was likely a bigger factor than heat.
After many years of hard work, North Coast dam removal efforts
are now rapidly accelerating. On Friday, Pacific Gas and
Electric Co. announced that it is pulling the application to
relicense the Potter Valley Project, a series of two dams and a
large diversion on the Upper Eel River. On Feb. 6, the
California Water Resources Control Board is coming to Arcata to
take comments on their final 401 (Clean Water Act) permit to
remove four dams on the Klamath River. What does this all mean?
Are we really about to see the Eel and Klamath River dams come
Before I started my fellowship at the Delta Stewardship
Council, I knew precisely two things about the Sacramento–San
Joaquin Delta: 1) its approximate location and 2) that, in some
way, it involved water. Fortunately for me, the nature of my
fellowship as a science communicator allowed me to learn a
little about a lot over a short period of time.
Congressmen John Garamendi and Doug LaMalfa have reintroduced
legislation to provide farmers access to discounted rates under
the National Flood Insurance Program. The
bipartisan Flood Insurance for Farmers Act of
2019 (H.R.830) would also lift the de
facto federal prohibition on construction and repair of
agricultural structures in high flood-risk areas designated by
the Federal Emergency Management Agency.
Warnings of doomsday on the river are nothing new. Too many
people, farms and factories depend on too little water, which
is why the Colorado now rarely flows to its end point at the
Gulf of California. The sprawling Southwest has sucked the
river dry. Yet the region has thrived in spite of the
naysayers. Until now, it appears.
The proposed tunnel path stretches 35 miles from west of Elk
Grove to just below Discovery Bay. The tunnels would take water
from three intakes along the Sacramento River to existing
aqueducts south of Discovery Bay, and then the water will be
sent to Southern California. Along the proposed path, there are
at least 22 levees that would sit above the tunnels….
The concern is not so much the levees themselves, but the kind
of soil that is below the levees.
A federal appellate court decision issued on January 25, 2019
will affect the relicensing of hydroelectric dams on the
Klamath River and efforts to accomplish dam removal under an
existing settlement agreement.
Maintaining functional wetlands in a 21st-century landscape
dominated by agriculture and cities requires a host of hard and
soft infrastructures. Canals, pumps, and sluice gates provide
critical life support, and the lands are irrigated and tilled
in seasonal cycles to essentially farm wildlife. Reams of laws
and regulations scaffold the system.
New data released measure changes in land subsidence in the
Sacramento Valley over the past nine years, finding the
greatest land surface declines in Arbuckle. According to the
Sacramento Valley GPS Subsidence Netwook Report and
accompanying fact sheet … land in the Arbuckle area has sunk
2.14 feet compared with baseline measurements recorded in the
same location in 2008, according to a press release from the
Department of Water Resources.
It took more than a decade to create, but a revised state
definition of wetlands and procedures to protect them from
dredge-and-fill activities requires still more work to make the
plan more clear and to reduce its impact on farmers, ranchers
Go deep into one of California’s most pressing issues –
groundwater – by visiting an extensometer that
measures subsidence, an active aquifer storage and recovery
well, a recycling facility that recharges water into the ground
Avoiding a long-expected crisis on the Colorado River, a water
source for 40 million people, is coming down to a final few
days of frenzied negotiations. A 19-year drought and decades of
overuse have put a water shortfall on the horizon. If
California and six other states, all with deeply entrenched
interests, can’t agree on a plan to cut their water consumption
by Jan. 31, the federal government says it will step in and
decide the river’s future.
City leaders met with Oregon state legislators this past week
to discuss the earliest stages of funding an $80 million
plan to fortify the city’s water system and ensure drinking
water is free from harmful algal toxins. The need for
cleaning out cyanotoxins and developing a backup water
system became apparent to city officials last summer when Salem
experienced a month-long drinking water crisis.
The California Department of Fish and Wildlife and the State
Water Resources Control Board, or SWRCB, are extending outreach
to the cannabis cultivating community with presentations at
four permitting workshops in Northern California. The
presentations are ideally suited for cannabis cultivators,
consultants and anyone interested in the topic. SWRCB will
cover policy and permitting, and other important information.
Computers will be available for applicants to apply for water
rights and water quality permits.
In Arizona, the Colorado River Drought Contingency Plan now
hinges on the approval of tribal nations. The plan is meant to
levy water cuts to seven Western states in order to prevent the
river and its reservoirs from reaching critical levels — but
after a state lawmaker introduced legislation that undermines
parts of the Gila River Indian Community’s water settlement,
the tribe has threatened to exit the plan. Without tribal
buy-in, Arizona’s implementation design will collapse….
Water conservation in the Las Vegas Valley is imperative as the
city continues to grow. The resources provided by the Colorado
River are stretched thin, as the river is responsible for
supplying the majority of the water to Southern Nevada, six
other states—California, Arizona, New Mexico, Wyoming, Utah,
Colorado—and Mexico. Combine these existing allotments with
drought conditions that have reduced the river’s average flows
by 30 percent annually, and it’s clear that Las Vegas must be
proactive in its conservation efforts.
The San Diego City Council is set to vote Tuesday on whether to
join a California lawsuit against the International Boundary
Water Commission (IBWC) over sewage flow from Tijuana, Mexico
into the United States. … The lawsuit alleges millions
of gallons of waste, including untreated sewage, trash,
pesticides and heavy metals have been discharged from the
IBWC’s treatment facilities in violation of the Clean Water
Droughts and floods have always tested water management, driven
water systems improvements, and helped water organizations and
users maintain focus and discipline. California’s
2012-2016 drought and the very wet 2017 water year were such
A federal court of appeals ruled Friday that PacifiCorp, which
currently owns and operates several dams along the Klamath
River, can no longer continue to use a controversial tactic
which has allowed the company to avoid implementing mandatory
requirements meant to protect the health of the Klamath River
for over a decade. The decision marks a victory for the Hoopa
Valley Tribe, who filed the lawsuit, and may expedite the
removal of several Klamath River dams.
