“The good news is that the San Joaquin Valley has managed to store a little more groundwater since the drought of 2016. The bad news is that it is hard to keep account of what’s working and what’s not.  On Tuesday, the Public Policy Institute of California, a nonprofit policy research organization, released an update report on the replenishment of groundwater in the San Joaquin Valley, one of the areas of the state that is heavily dependent on groundwater. The report also identified those basins best suited to accept water recharge operations, with the highest number being in the eastern and southern regions of the valley.  In late 2023, following a very wet winter and spring, the institute surveyed recharge activities in local water agencies. … They found a 17% increase in the total water volume that was recharged in the valley, including areas that use only groundwater. … ”  Read more from SF Gate.

Sparks fly as Tule basin agency is accused of being “unable and unwilling” to curb over pumping

“Fireworks were already popping between board members of a key Tulare County groundwater agency recently over an 11th hour attempt to rein in pumping in the severely overdrafted area.  The main issue at the Eastern Tule Groundwater Sustainability Agency (GSA) meeting June 6 was whether to require farmers in subsidence prone areas to install meters and report their extractions to the agency, which is being blamed for almost single handedly putting the entire subbasin in jeopardy of a state takeover.  “I don’t know why we’re sitting here massaging this thing knowing damn well the state told us to do this,” said Eastern Tule board member Matt Leider of requiring the meters.  But fellow board member Eric Borba pooh poohed the need for urgency, suggesting the board take things “one step at a time.” … ” Read more from SJV Water.

Defining the ‘significant and unreasonable’ inadequacies in subbasin GSPs

“Despite varying interests and distinct stakeholder needs, one thing Groundwater Sustainability Agencies can collectively agree on is the need to avoid a probation determination from the State Water Resources Control Board.  Of the six critically overdrafted basins in the Central Valley, only the Tulare Lake Subbasin has officially been placed on probation. While the six basins cover different areas with unique water needs and landowner interests, there are several commonalities in the deficiencies the SWB found within the separate groundwater sustainability plans.  State Water Board staff has released three probationary hearing draft staff reports for the following basins — Tulare, Tule, and Kaweah. The subbasin GSPs share three specific inadequacies: chronic lowering of groundwater levels with insufficient Sustainable Management Criteria, continued land subsidence, and further degradation of groundwater quality. … ”  Read more from Valley Ag Voice.

California and Tribal partners secure critical water supply to support Native American farmers

“”Working together to support local Tribal farmers, the Department of Water Resources (DWR) and Santa Rosa Rancheria Tachi Yokut Tribe have expedited two water transfers to meet immediate water supply needs and to address long-term demands north of the Tulare Lake area. Working with the Tulare Lake Irrigation District, DWR and the Tachi Yokut Tribe entered into a contractual agreement to institute both a temporary and permanent transfer of water resulting in over 600-acre feet of additional water for the area.  “California remains committed to getting water to communities that need it most. This successful effort is a direct result of meaningful consultation and communication with our Tribal partners and the hard work of our staff to ensure we can move water to places in critical need,” said DWR Director Karla Nemeth. … ”  Read more from DWR.

Program to delay harvest protects birds and farmers

Listed as threatened under the California Endangered Species Act, tricolored blackbirds often build nests on dairy farmers’ forage crops due to loss of native habitat. To protect the birds and themselves from liability, farmers agree to delay harvest of their crops under a voluntary local program, which compensates them for crop losses due to the delay. Photo/National Audubon Society

“For multiple years, Simon Vander Woude’s Merced County dairy farm has served as a refuge for an imperiled bird species that has increasingly looked to agricultural fields as a nesting ground.  By agreeing to delay harvest where tricolored blackbirds nest, Vander Woude and other California farmers are helping to save a species that once faced potential extinction.  Tricolored blackbirds, which gained protection as threatened under the California Endangered Species Act in 2018, historically nested in freshwater marshes. But the loss of native wetland habitat has forced them to rely on winter silage fields planted by dairy farmers.  Because of the birds’ protected status, finding them in the field creates a hardship for farmers, as nesting season coincides with harvest and other farming activities. … ”  Read more from Ag Alert.

The nation’s most polluted beach is in California, study finds

“With summer just around the corner and the weather finally heating up, beach season is about to be in full swing, and beachgoers are flocking to the coasts of the United States in search of warm sand and a cool ocean breeze.  Many U.S. beaches often get recognition for this appeal, but several beaches recently received a less than favorable acknowledgment from a national environmental group as the most polluted beaches in the entire country.  Last year, labs run by Surfrider’s Blue Water Task Force processed 9,538 water samples collected from 567 distinct sampling sites around the U.S. Of the 567 beaches sampled, 362 of them yielded at least one high bacteria result that exceeded state health standards. … ”  Read more from KTLA.

The meaning of Dos Rios, California’s newest state park

“On Wednesday, June 12, the state of California officially opens Dos Rios, the first new state park in more than a decade. It’s a riparian forest restoration at the confluence of the San Joaquin and Tuolumne rivers, in the Central Valley, about an hour from San Jose—and the subject of Bay Nature’s Spring 2024 cover story, “The Everything Park,” by H.R. Smith.  We dubbed Dos Rios the Everything Park because a modern state park has an astonishing number of jobs to do—among them groundwater storage, wildlife habitat, and climate adaptation. People destroyed nearly all of the Central Valley’s riparian forest for agriculture or urban areas over the past century. This 1,600-acre restoration, which was led by the nonprofit River Partners, is part of an ambitious plan to restore 100,000 acres. (Seeing the landscape-scale engineering of this—how farmland has been transformed into floodplain—is fascinating, and worth a visit.) … ”  Read more from Bay Nature.

Healthy river advocates urge support for bill to improve climate resilience in coastal watersheds

“The California Salmon and Steelhead Coalition, a partnership comprised of California Trout, The Nature Conservancy, and Trout Unlimited, is calling on Governor Newsom to support Assembly Bill 1272 (Wood). This bill will ensure a climate-resilient future for California’s coastal watersheds, which support vibrant communities, important ecosystems, and iconic species.  The bill, authored by Assemblymember Jim Wood (D-Healdsburg), directs the State Water Resources Control Board and the California Department of Fish and Wildlife to develop guidelines for water use in certain coastal watersheds during times of water shortage. These principles and guidelines will allow for the development of locally generated watershed-level plans to protect public trust uses, public health and safety, and the human right to water. The plans will help water users anticipate how their businesses and communities will be impacted by drought, providing an incentive to invest in solutions that increase preparedness. AB 1272 passed both houses of the legislature in 2023 without opposition and awaits being sent to the Governor for his signature. … ”  Read more from The Nature Conservancy.

Should clean air and water be the right of every Californian? Not everybody thinks so

“A contentious proposal to amend California’s Constitution to enshrine environmental rights for all citizens has been delayed for at least another year after it failed to gain traction ahead of a looming deadline.  ACA 16, also known as the green amendment, sought to add a line to the state Constitution’s Declaration of Rights affirming that all people “shall have a right to clean air and water and a healthy environment.”  The single sentence sounds straightforward enough, but by the start of this week, the proposal had not yet made it through the state Assembly or moved into the state Senate. Both houses would need to pass the proposal by June 27 in order to get it on voter ballots this fall. … ”  Read more from the LA Times.

How California can rewrite the extraction business model and boost Salton Sea communities

Silvia Paz, executive director of Alianza Coachella Valley, writes, “California is at a policy and fiscal crossroads. It must decide whether to rewrite the extraction business model to benefit impacted communities, or to continue with the traditional model that causes unmitigated environmental and economic injustices.  The Salton Sea region is facing economic pressure to become a substantial domestic supplier of lithium, placing greater challenges on lower-income communities that already face significant disparities – yet contribute so much to the prosperity and quality-of-life of others. Without meaningful investment, these communities will fall further behind as their needs are sidelined in the rush for lithium development.  This is a story all too real to the farm laborers and low-wage tourism workers who call this region home. … ”  Read more from Cal Matters.

Restoring American River spring-run chinook salmon

“For decades, the possibility of restoring spring-run Chinook salmon in the American River has been ignored. With recent changes to the Nimbus Hatchery fish ladder and federal and state mandates to focus more on the recovery of Central Valley spring-run Chinook, it is time to recover the American River’s spring-run salmon.  The American River spring-run were never really lost. The river has always had modest numbers of these iconic salmon that attracted fishermen and even guides each spring to the lower river below Nimbus Dam. It wasn’t much of a secret. It was more common knowledge and a nice complement to spring shad and steelhead fishing. These spring-run salmon were generally believed to be strays from other Sacramento River spring-run streams and the Feather River Fish Hatchery. … ”  Read more from California Fisheries.

Triple-digits to bring wave of water

“Triple-digit heat arrived last week and will hang around this week bringing more water down the mountain to Tulare County.  This week’s forecast shows 95 degrees or above every day and a high of 105 for a number of them. Bakersfield, Fresno and Visalia could all match or set new record warm night-time temperature records. The first heat wave of 2024 hit inland California last week, and a spell of exceptionally warm nights.  That will bring down the snowpack in a hurry in the Sierra over the next two weeks with our dams already at capacity. The Sierras stored more water in snowpack than anticipated meaning the Friant-Kern Canal will receive uncontrolled spill from Friant Dam weeks longer than expected. That has led to a 5% surplus of Class II water supply adding to its 100% of contracted or Class I water supply. … ”  Read more from the Foothills Sun-Gazette.

“Evidence is stacking up against the state in one of multiple lawsuits over last year’s devastating floods in Merced County. One of the most stunning new pieces of evidence is a string of 12 emails from Merced County staff that went ignored by the state for more than four months before last year’s floods.  The lawsuit was filed against the California Department of Fish and Wildlife (CDFW) on behalf of the City of Merced, a local elementary school and 12 agricultural groups. All the plaintiffs took significant damage from flooding after water backed up in clogged waterways and broke through, or overtopped creek banks and levees.  The flooding came primarily from Bear Creek and Black Rascal Creek, both of which have flooded before. Flooding from Miles Creek also damaged nearly every home in the small, rural town of Planada. … ”  Read more from SJV Water.

Commentary: Ag-to-urban bill saves groundwater while building the housing Arizona needs

Craig McFarland, mayor of Casa Grande, writes, “Arizona’s challenges with water supply and housing affordability are linked. But not in the way you may think.  Despite a roughly seven-fold population increase, Arizona actually uses less water now than it did in the mid-1950s.  Improvements in agriculture and farming water efficiency have helped make this possible, but it’s largely due to the state’s transition from water-intensive agricultural activities to less thirsty residential and domestic uses.  Now, this same phenomenon has the ability to not only generate massive water savings and take pressure off Arizona’s limited groundwater supply, but also combat a housing shortage that has made Arizona one of the most expensive places to live. … ”  Read more from Arizona Central.

Tucson’s groundwater is partially contaminated by ‘forever chemicals.’ Feds want it fixed

Its reservoir is primarily filled by snowmelt from the Rocky Mountains that feeds into the Colorado River along its upper basin states: Utah, New Mexico, Colorado and Wyoming. Glen Canyon then works as a network that sends water to lower basin states, including Nevada, Arizona and California.  In 2022, it saw a record shrinkage — the lowest it had been since the 1960s when it was filled — but the last two years have brought wet winters, which are showing some signs of recovery for the massive lake.

Billion-dollar weather disasters are soaring again this year. Here’s why.

“May was another exceptionally busy month for severe thunderstorms and tornadoes in the United States, pushing weather disaster costs to their second-highest amount on record to date. Eleven separate billion-dollar weather disasters this year have together caused over $25 billion in damage and 84 deaths. Two such storm disasters occurred in May, the National Oceanic and Atmospheric Administration reported Monday, including the violent storm complex that blasted Houston mid-month, killing seven people. The repeated, costly thunderstorm outbreaks fit into a trend toward more such incidents that are driving a surge in weather-related property damage and insurance payouts across the United States.

Expecting the unexpected could help us prepare for climate extremes

“The U.S. Pacific Northwest experienced an unprecedented heat wave in summer 2021, with many locations in the region breaking all-time maximum temperature records by more than 9℉ (5℃). Although weather models forecasted the warmer-than-average conditions that summer, the extreme temperatures caught the climate science community by surprise. In the past year, so have catastrophic, deadly floods in such places as Libya and China and record-breaking wildfires in Canada.  Our collective unpreparedness for such extreme climate events should be a cause for concern, argue Sherwood et al. The authors contend that a reliance on models that don’t account for enough relevant factors and a tendency toward linear thinking have narrowed perceptions of climate change risks.  Central to their argument is the idea that society is too focused on the expected gradual consequences of climate change and not enough on high-impact, low-likelihood occurrences and tipping points—regime shifts in which systems can change rapidly and irreversibly. The authors suggest that as a result, we are overlooking critical potentialities in our efforts to adapt to and weigh mitigation options for a warmer future. … ”  Read more from EOS.

Environmental Defense Fund to study effects of artificially cooling earth
