Acronyms are so prevalent in the water industry that stringing
several together can form an impressive-sounding
sentence. That’s exactly what Hanford High School junior
Morgan Carroll did at an April 5 workshop in Sacramento called
Water 101 put on by the Water Education
Foundation. After winning a game of bingo no
less. The bingo game kept the audience of water managers and
government and nonprofit employees on its toes during a talk on
what could be a very dry topic, especially after lunch: The
role of regulatory agencies in state and federal water law.
… Part of being on the team is keeping tabs on current
events in the water industry. Students subscribed
to Aquafornia, the foundation’s daily
news summary, and found out about the workshop that way.
They’re in makeup, dental floss and menstrual products. They’re
in nonstick pans and takeout food wrappers. Same with rain
jackets and firefighting equipment, as well as pesticides and
artificial turf on sports fields. They’re PFAS: a class of
man-made chemicals called per- and polyfluoroalkyl substances.
They are also called “forever chemicals” because the bonds in
their chemical compounds are so strong they don’t break down
for hundreds to thousands of years, if at all. They’re also in
our water. A new study of more than 45,000 water samples
around the world found that about 31 percent of groundwater
samples tested that weren’t near any obvious source of
contamination had PFAS levels considered harmful to human
health by the Environmental Protection Agency.
Wetlands have flourished along the world’s coastlines for
thousands of years, playing valuable roles in the lives of
people and wildlife. They protect the land from storm surge,
stop seawater from contaminating drinking water supplies, and
create habitat for birds, fish and threatened species. Much of
that may be gone in a matter of decades. As the planet warms,
sea level rises at an ever-faster rate. Wetlands have generally
kept pace by building upward and creeping inland a few meters
per year. But raised roadbeds, cities, farms and increasing
land elevation can leave wetlands with nowhere to go. Sea-level
rise projections for midcentury suggest the waterline will be
shifting 15 to 100 times faster than wetland migration has been
clocked. -Written by Randall W. Parkinson, Research Associate

University.
Pasadena Water and Power (PWP) has launched a new multi-year
campaign called “The Ripple Effect” aimed at promoting water
sustainability and resilience in the community. Acting General
Manager David Reyes urged all PWP customers to become local
water stewards for Pasadena and the region by participating
in the campaign. “We invite every member of our
community to embrace their role as local water stewards,” said
Reyes. “Each one of us holds a vital place in shaping
Pasadena’s water future.” About one-third of
Pasadena’s water supply comes from local groundwater, with the
remaining two-thirds imported from other sources. PWP
emphasized that understanding where the community’s water comes
from helps foster a greater appreciation for
this critical resource.
The California Department of Transportation (Caltrans) begins
construction this month to install a trash capture device along
northbound State Route 99, preventing trash in storm water
runoff from entering the Tuolumne River at Zeff Road. The trash
capture system will be located at the inlet of two existing
culverts on the southeast side of SR-99 and the Tuolumne River,
a location identified as a significant trash generating area.
The project will help the department achieve zero trash from
stormwater discharge into the lower reaches of the Tuolumne
River. It is consistent with the Caltrans’ Statewide Trash
Implementation plan and in compliance with the State Water
Resource Control Board water quality objectives for trash
pollutants.
… U.S. Geological Service data shows Teton Valley’s aquifer
steadily declined in recent decades as development increased
and crop watering systems became more efficient, reducing
infiltration by replacing flood irrigation with pivots and
sprinklers. In addition, the area’s transition from
agricultural valley to recreation hub has meant less acreage
being watered: farms replaced by subdivisions full of houses
with domestic wells, each one a straw guzzling from the
valley’s all-important aquifer. … Recharge has benefited
farmers and fish in western communities like Idaho’s Eastern
Snake River Plain and California’s Central Valley, and the
group believes the data shows it can work in the Teton Basin.
They hope it can. In addition to providing a bulwark against
future water shortages or legislative changes to water rights
laws, they want to do something groundbreaking: create a
market-based system to pay farmers for incidental recharge.
The Nesting Bird Habitat Incentive Program is still accepting
applications for the Delayed Cereal Grain Harvest and Fallow
Agriculture programs until end of day Wednesday, April 10. If
you have winter planted cereal grains, winter planted cover
crops or farm fields that will be left fallow this growing
season, these programs could be a great fit for your
operations. You must be willing to leave them undisturbed and
or delay harvest until at least July 15th. Below are key
details for each of the program.
Genes are the blueprints that inform development and behavior,
and over time they are molded by evolution into adaptations
that allow species to persist in an ever-changing world.
However, animals adapted to one environment sometimes find
themselves suddenly dropped in another. Such is the case for
certain hatchery-raised steelhead (Oncorhynchus mykiss) in
California’s Central Valley. The genes of steelhead play an
important role in determining their life history, and may
influence the timing of migration and maturation. To evaluate
how such genes may be impacted by hatchery practices,
researchers from UC Santa Cruz and the National Marine
Fisheries Service dove into the genetics of steelhead from four
hatcheries in the Sacramento River Basin (Goetz et al. 2024).
The findings of their investigation show just how influential
genes are in determining the path that a steelhead’s life will
take.
Powerful pumps that supply much of California’s population with
water have killed several thousand threatened and endangered
fish this year, prompting a coalition of environmental groups
to demand that state and federal agencies take immediate steps
to limit “alarming levels” of deaths. In
a letter to state and federal water managers, leaders
of five fishing and environmental groups said the estimated
losses of threatened steelhead trout and endangered winter-run
Chinook salmon have exceeded maximum annual limits for water
intakes in the Sacramento-San Joaquin River Delta.
Spring storms brought more snow to mountains across the Western
U.S., bringing water for struggling Lake Powell with them. The
National Weather Service Colorado Basin River Forecast Center
on Friday estimated that Lake Powell will receive 5.7 million
acre-feet of water between April and July as snow melts off the
mountains. An acre-foot is roughly enough water to sustain two
houses for a year. That volume is 89% of the normal runoff for
that time period recorded between 1991 and 2020. Facing
extreme drought and climate change since the turn of the
century, Lake Powell dropped to a historic low of 22%
full in Feb. 2023. The reservoir currently stands at
about 32% full.
New California legislation seeks to permanently ban paraquat, a
powerful and widely used weedkiller that has been linked to
Parkinson’s disease and other serious health issues. Assembly
Bill 1963, introduced recently by Assemblymember Laura Friedman
(D-Glendale), would sunset the use of paraquat beginning in
January 2026. The herbicide, which is described by the U.S.
Environmental Protection Agency as highly toxic, is regularly
sprayed on almonds, grapes, cotton and other crops in the
state. … California is the nation’s top user of paraquat
…
The Navajos live in the same 1,400-mile-long Colorado River
Basin that brings fresh water to millions in Southern
California, yet about 30% of homes on the reservation were
built without indoor plumbing. With the absence of pipes
connecting homes in this isolated corner of the reservation to
a water source, many Navajos must spend hours each week driving
to a community center in the tribal settlement of Dennehotso to
refill portable tanks. … Some see hope in a
proposed landmark agreement that would settle all
outstanding water rights disputes between the Navajo, Hopi and
San Juan Southern Paiute tribes and the state of Arizona. If
the final terms of the agreement are approved by the tribal
government, the Navajos will ask Congress for $5 billion in
federal funding to expand the reservation’s water delivery
infrastructure.
Arizona House Republicans convened in a newly created committee
Thursday afternoon to discuss an investigation into the state’s
Democrat attorney general. The conservative lawmakers announced
the creation of the House Committee on Executive Oversight
Wednesday in response to Attorney General Kris Mayes’ ongoing
investigations into “megafarms” she says are overusing
groundwater and draining the wells of rural Arizonans. …
Mayes has recently indicated in multiple town halls across
rural Arizona, specifically La Paz County, her intent to file a
public nuisance complaint against large industrial farms and
corporations that she says are sucking rural Arizonans dry.
Nearly half of US prisons draw water from sources likely
contaminated with toxic PFAS “forever chemicals”, new research
finds. At least around 1m people incarcerated in the US,
including 13,000 juveniles, are estimated to be housed in the
prisons, and they are especially vulnerable to the dangerous
chemicals because there is little they can do to protect
themselves, said Nicholas Shapiro, a study co-author at the
University of California in Los Angeles.
After years of heated debates and delays, the world’s largest
dam removal is currently underway on the Klamath River across
the California-Oregon border. … removing structures of
this size come with negative side effects—from droves of dead
fish to muddy waters. As a result, critics have recently spoken
out against the project, deeming it an “environmental
disaster.” But scientists say that they expected many of these
short-term impacts before the effort began and they will soon
fade. For today’s newsletter, I decided to dig into the science
behind dam removal, and how the rocky start to the Klamath
River project could yield a healthier river system overall.
A bill that would allow graywater systems to be included in new
homes throughout Colorado received rare unanimous approval from
the Colorado House on Friday. Graywater is made up of water
that has been used a single time from appliances like laundry
machines, baths or sinks and can be used again for non-drinking
purposes like toilet flushes and irrigation. Conservationists
point to graywater uses as a way to cut down on water
consumption as the drought in the West has deepened in recent
years.
Hydropower generated for electricity from Oregon and Washington
dams fell to historically low levels last year, and experts
expect it could drop further by year’s end. Officials at the
U.S. Energy Information Administration recently published data
showing that hydropower generation in the Northwest between
Oct. 1, 2022 and Sept. 30, 2023 dropped to a 22-year
low. … Across the West, hydropower generation in
2022 and 2023 was down 11% from 2021, according to the data.
California was an outlier, doubling the amount of hydropower
generated due to record rainfall and snowpack.
… [C]occidioides, a fungus that causes a disease called
coccidioidomycosis, better known as valley fever. If inhaled,
microscopic spores from the fungus can lodge in the lungs.
About a third of those infected with cocci never have any
symptoms, and most of those infected clear the disease and
develop immunity. But for between 1 and 5% of those who inhale
it, cocci spreads through the bloodstream and wreaks havoc in
the body that can sometimes be lethal. And the changing climate
has allowed valley fever to spread far beyond its traditional
territory of Arizona and parts of Southern California.
The Marin Municipal Water District has adopted its strategic
work plan as it strives to reduce potable water use and
increase supply. The work plan, approved unanimously at
Tuesday’s board meeting, outlines the steps needed to implement
the five-year strategic plan the district adopted in February.
The strategic plan includes targets for water supply, drought
resiliency, land stewardship and fiscal responsibility.
After 12 years of planning, gathering funding then completing
and re-doing – and re-doing again – environmental studies, the
City of Bakersfield has finally gone out to bid for the
northern extension of the Kern River Parkway Trail. “I’m very
excited, it’s been a long time coming,” Councilman Bob Smith
said of the 6-mile long addition to the nearly 40-mile-long
path that runs the length of the Kern River from Gordon’s Ferry
on the east all the way to the Buena Vista Lake Aquatic
Recreation Area on the west. This extension will take runners,
hikers and cyclists north at Coffee Road along the Friant-Kern
Canal up to 7th Standard Road, about a half mile west of the
Gossamer Grove development.
