The attention is on Southern California right now, but an
atmospheric river’s path will extend inland with potential
flooding — and possible drought relief. If you’re watching the
weather, it’s still a little early to tell whether these storms
will go where they can hope Las Vegas the most. That’s anywhere
in the Upper Colorado River Basin, where there’s a chance they
could produce snow to help the river that supplies 90% of the
water used in Southern Nevada. … The paths of this
year’s atmospheric rivers are unlike the ones that slammed
the Sierras last year. Those storms carried snow straight
east through Northern Nevada and Utah, feeding the Rocky
Mountains with snowpack levels that reached 160% of normal by
the end of winter.
Beyond evacuations, mudslides, outages and road flooding, the
atmospheric river that drenched Southern California over the
last few days brought eye-popping rainfall totals to the region
— with still more to come Tuesday. Rainfall topped 11 inches in
some areas of Los Angeles County in three days, easily
surpassing the average amount recorded for the entire month of
February, according to the National Weather Service. “And
February is our wettest month,” said Ryan Kittell, a
meteorologist with the National Weather Service in Oxnard… As
of 10 p.m. Monday, downtown Los Angeles had recorded 7.04
inches of rain over the prior three days. The February average
is 3.80 inches. That three-day total is nearly 50% of the
average amount of rainfall for an entire year for downtown Los
Angeles.
Last week, Assemblywoman Esmeralda Soria introduced AB 2060 to
help divert local floodwater into regional groundwater
basins. AB 2060 seeks to streamline the permitting process
to the California Department of Fish and Wildlife in support of
Flood-MAR activities when a stream or river has reached
flood-monitor or flood stage as determined by the California
Nevada River Forecast Center or the State Water Resources
Control Board (SWRCB). This expedited approval process would be
temporary during storm events with qualifying flows under the
SWRCB permit.
Partners have pulled together to support the recovery of
endangered Sacramento winter-run Chinook salmon in the last few
years. However, the species still faces threats from climate
change and other factors. That is the conclusion of an
Endangered Species Act review that NOAA Fisheries completed for
the native California species. It once returned in great
numbers to the tributaries of the Sacramento River and
supported local tribes. The review concluded that the species
remains endangered, and identified key recovery actions to help
the species survive climate change. While partners have taken
steps to protect winter-run Chinook salmon, blocked habitat,
altered flows, and higher temperatures continue to threaten
their survival.
Water regulation in Arizona has devolved into a game of
chicken. The governor and farmers are rivals revving their
engines, hoping their opponent will flinch first. Caught
in the middle is Gila Bend, a groundwater basin south of
Buckeye, where the state could decide to impose its most
stringent form of regulation, whether folks like it or not.
Both sides are using Gila Bend as a bargaining chip to win
support for competing legislative proposals. But to what
end? - Written by Joanna Allhands, Arizona Republic digital

The continued wet weather in the Northstate has left quite an
impact at Shasta Lake. California’s largest reservoir rose a
foot from Thursday to Friday, and 5 feet from January 26 to
February 2. Currently, Shasta Lake sits at 1,035 feet, roughly
30 feet from capacity. That’s an increase of 47 feet from this
date last year. … Overall, the weather station at Shasta
Dam has reported 36.56 inches of rain since the water year
began on October 1.
Tesla will pay several district attorney’s offices $1.5 million
over violations of hazardous waste laws, per an agreement it
reached this week in San Joaquin County Superior Court. The
payment stems from Tesla’s handling, transporting and disposing
of hazardous materials from its facilities in California. Tesla
knew about policies and procedures for handling that waste and
violated the law by disposing of waste at unauthorized spots.
It also failed to determine whether waste created at its
facilities was hazardous and didn’t properly label and store
it.
Colorado legislators in 2022 passed a bill that delivered $2
million to programs across the state for removal of turf in
urban areas classified as nonfunctional. By that, legislators
mean Kentucky bluegrass and other thirsty-grass species that
were meant to be seen but rarely, if ever, otherwise
used. Now, they are taking the next step. The Colorado
Senate on Tuesday, Jan. 30 voted in favor of a
bill, Senate Bill 24-005, that would prevent thirsty turf
species from being planted in certain places that rarely, if
ever, get foot traffic, except perhaps to be mowed.
The U.S. Senate Indian Affairs Committee is holding an
important hearing Thursday on S. 2385, a bill to
refine the tools needed to help Tribal communities gain access
to something that most non-Indian communities in the western
United States have long taken for granted: federally subsidized
systems to deliver safe, clean drinking water to our homes.
… This is the sort of bill (there’s a companion on the
House side) that makes a huge amount of sense, but could easily
get sidetracked in the chaos of Congress. The ideal path is for
the crucial vetting to happen in a process such as Thursday’s
hearing, and then to attach it to one of those omnibus things
that Congress uses these days to get non-controversial stuff
done. Clean water for Native communities should pretty clearly
be non-controversial.
How will selling groundwater help keep more groundwater in the
San Joaquin Valley’s already critically overtapped aquifers?
Water managers in the Kaweah subbasin in northwestern Tulare
County hope to find out by having farmers tinker with a pilot
groundwater market program. Kaweah farmers will be joining
growers from subbasins up and down the San Joaquin Valley
who’ve been looking at how water markets might help them
maintain their businesses by using pumping allotments and
groundwater credits as assets to trade or sell when water is
tight.
State health officials know that extreme heat can cost lives
and send people to the hospital, just like wildfire smoke. Now,
new research finds that when people are exposed to both hazards
simultaneously — as is increasingly the case in California —
heart and respiratory crises outpace the expected sum of
hospitalizations compared to when the conditions occur
separately. … The study joins a growing body of research
about the intersection of different climate risks. Last month,
California-based think-tank the Pacific
Institute published a report about how converging
hazards — including wildfires, drought, flooding, sea level
rise and intensifying storms — are harming access to drinking
water and sanitation in California and other parts of the
world. The deadly 2018 Camp fire in Butte
County impacted an estimated 2,438 private wells, the
report said.
For as long as he can remember, Rob Sowby has heard people call
Utah the second-driest state in the nation. Over the years,
that claim has become nearly inescapable, echoed by everyone
from state departments, city governments and water conservancy
districts to national news outlets without a clear citation for
what data it’s based on. … Now a Brigham Young
University civil engineering assistant professor focused on
sustainable water supplies, he decided to get to the bottom of
it. Using precipitation data, he found that Utah is actually
the nation’s third-driest state, behind Nevada and
Arizona.
The dam removal projects- aimed at sustaining the salmon
population, are underway, with the latest drawdown being three
reservoirs on the Klamath River. The removal process has
already dramatically changed the landscape in Southern Oregon
and far Northern California, along the course of the river. The
lowest of the three remaining dams- Iron Gate, was initially
breached on January 9, followed by the J.C. Boyle reservoir on
January 16. A concrete plug in the tunnel at the base of Copco
1 was blasted away on January 23, with the reservoirs draining
quickly, leaving vast expanses of fissured mud that was the
consistency and color of chocolate cake batter. Shaping its new
course, the Klamath River is winding through the bare
landscape, but the transformation has had some unintended
consequences and saddened some residents.
An “extremely dangerous situation” was unfolding in the
Hollywood Hills area and around the Santa Monica Mountains
Monday, as a powerful, slow-moving storm triggered mud flows
and debris flows that damaged some homes and forced residents
to evacuate. Damage reports piled up early Monday as the storm
system steadily pummeled Southern California, and downtown L.A.
broke a 97-year-old rainfall record. On Sunday, downtown
had seen 4.1 inches of rain, which broke the record for the
calendar day set on Feb. 4, 1927, when 2.55 inches of rain was
recorded. Sunday was the third wettest February day on record
and tied for the 10th wettest day for any time of year since
record keeping began in 1877, the National Weather
Service said.
The return of fully planted rice crops to the Sacramento Valley
following years of drought has restored another essential
feature of the region. After harvest, reservoirs replenished by
last year’s historic storms enabled farmers to flood more of
their fields this winter, creating wetland habitat for
migrating waterfowl. … Today, around 300,000 acres of the
valley’s rice paddies are flooded each winter to provide food
and shelter for 7 million ducks and geese, according to the
California Rice Commission. More than 200 species of wildlife,
including threatened species such as Sandhill Cranes, rely on
the fields. Especially over the past decade, state and federal
programs have been developed to incentivize winter flooding,
defraying some of the cost, and rice farmers have embraced
their role in wildlife conservation.
… In California, just figuring out who holds a water right
requires a trip to a downtown Sacramento storage room crammed
with millions of paper and microfilmed records dating to the
mid-1800s. Even the state’s water rights enforcers struggle to
determine who is using what. … Come next year, however,
the board expects to have all records electronically accessible
to the public. Officials recently started scanning records tied
to an estimated 45,000 water rights into an online database.
They’re also designing a system that will give real-time data
on how much water is being diverted from rivers and streams
across the state. … Proponents say the information
technology upgrade will help the state and water users better
manage droughts, establish robust water trading markets and
ensure water for fish and the environment.
Twenty early to mid-career water professionals from
across California have been chosen for the 2024 William R.
Gianelli Water Leaders cohort, the Water Education Foundation’s
highly competitive and respected leadership
program. The cohort includes engineers,
lawyers, resource specialists, scientists and others from a
range of public and private entities and nongovernmental
organizations.
… California’s 2024 Water Year could still be quite dry
and/or bring floods, but it seems unlikely to become among
California’s wettest years, if only because the water year’s
first months have been dry. Today, the Northern Sierra
precipitation index is about 66% of average for this time of
year. San Joaquin and Tulare basin precipitation indices
are at 46% and 40% of average, respectively. … Given the
precipitation so far, 2024 is highly likely to be wetter than
the very driest years of record, but is also highly unlikely to
be among the very wettest years in the past 100 years or
so.
The Topock Marsh has seen a significant drop in water levels
recently, with dry patches visible and locals concerned about
the effects on wildlife. The 4,000-acre Bureau of Reclamation
marsh is adjacent to the Colorado River in the Havasu National
Wildlife Refuge. Managed by the U.S. Fish and Wildlife Service,
it serves as a recreation area and wildlife habitat for the
Tri-state.
… Without more investment and regulatory relief,
Californians face a future of chronic water scarcity. Our
system of water storage and distribution is in trouble. We have
depleted aquifers, nearly empty reservoirs on the Colorado
River, and a precarious network of century-old levees that are
one big earthquake away from catastrophic failure. Then there’s
always the next severe drought. Even if the governor
aggressively pushes for more investment in water supply
infrastructure and more regulatory relief so projects can go
forward, the state is again staring down a budget deficit.
Bonds to fund water infrastructure projects are going to have a
hard time getting approval from voters already overburdened
with among the highest taxes in America. - Written by Edward Ring, senior fellow with the
California Policy Center.
