  • WEBINAR: Voyage into the Past: Stories from the California Current: What Happens to Coral Reefs Hit by Disease? from 11am to 11:30am.  The USGS studies the roles that coral reefs play for shoreline protection, fisheries benefits, and tourism-based economies. Many Caribbean coral reefs are near collapse due to various threats. An emerging threat, stony coral tissue loss disease (SCTLD), is spreading across the Western Atlantic and Caribbean. Data from the U.S. Virgin Islands reveal how SCTLD spread has reduced the abundance of susceptible coral and crustose coralline algae and increased cyanobacteria, fire coral, and macroalgae. Some reef fishes will decline due to SCTLD, with the largest changes on reefs that lose the most susceptible corals and rugosity. Mapping these projected declines in space indicates how the indirect effects of SCTLD range from undetectable to devastating. The origins of SCTLD and whether it may spread beyond the Caribbean have implications for coral reefs in the U.S. Pacific.  Click here to enter the webinar.

California dodges a bullet on Colorado River cuts

“California and two other states have avoided the harshest water cutbacks the Trump administration could have imposed over the next two years to deal with the deepening crisis on the Colorado River.  The Times has learned that federal officials have agreed with an offer made earlier this year by California, Arizona and Nevada to reduce what they take from the river by at least 3.2 million acre-feet between now and the end of 2028.  Under the plan, California will cut its use of Colorado River water by about 12% through 2028, Arizona will take about 31% less and Nevada 28% less, according to two officials at state and local agencies who spoke anonymously since details of an announcement are still being finalized. … ”  Read more from the LA Times. | Read via Yahoo News.

Groundwater pumping increases subsidence creating major damage

“Corcoran is the proverbial canary in the mine when it comes to the invisible damage droughts are likely to inflect.  Between May of 2015 and September 2016 areas near the South San Joaquin Valley community dropped upwards of 25 inches in during that drought due to land sinking with the removal of water from underground aquifers.  The subsidence was the end result of jacked up groundwater pumping due to the Bureau of Reclamation cutting off water deliveries as growers scrambled to protect hundreds of millions of dollars invested in cropland and orchards.   … When 2017 delivered one of the wettest winters on record for the San Joaquin River water basin to break the back of the last drought, the Friant Water Authority could not use its canals at full capacity to deliver water to farmers.  That’s due to subsidence including one segment where the capacity was compromised by 40 percent with most of the loss occurring between 2016 and 2017. Subsidence just doesn’t damage and compromise canals. It also impacts bridges, roads, power lines, and even structures. … ”  Read more from the Manteca Bulletin.

New report documents challenges and applications for telemetered water monitoring and a path forward for California

“The California Water Data Consortium and partners recently released a new report with statewide telemetered water monitoring recommendations for the State Water Resources Control Board (SWRCB). The three-part report synthesizes lessons from global telemetry networks, outlines recommendations for a watershed-scale research study, and identifies practical statewide applications for telemetry to support California’s evolving water management needs.  Telemetry, the automatic collection and transmission of data through cellular, radio, or satellite communications pathway, has the potential to dramatically improve the speed and accessibility of water data needed for critical decision making. With the State Water Board’s launch of the California Water Accounting, Tracking, and Reporting System (CalWATRS) last year, California is better positioned to receive and use water data in near real time. However, telemetered water monitoring networks can be costly and technically complex to install, operate, and maintain over the long term. As a result, the state needs stronger research and clearer guidance on where telemetry investments are most critical, effective, and cost-efficient. … ”  Read more from the Water Data Consortium.

El Niño could become the strongest on record. Hawaii may feel it first

“The Pacific Ocean is exceptionally warm. Years-long marine heat waves, including one along the Southern California coast, are now overlapping with a rapidly intensifying El Niño that could become the strongest on record.  With the world’s largest ocean loaded with an extraordinary amount of heat, weather patterns around the globe – including in California – could see major impacts in the fall and winter.  Hawaii may not have to wait that long.  In past summers preceding a strong El Nino, more tropical storms and hurricanes have tracked close to the islands than in non El Niño years — with August and September a particularly dangerous stretch. Already, a weak spot may be opening in one of the islands’ usual atmospheric defenses against these powerful storms, similar to what has allowed past cyclones to march toward the islands in a strong El Niño year. … ”  Read more from the San Francisco Chronicle.

PG&E’s data center pipeline more than doubles in second quarter

“PG&E Corp. reported a 7.6-gigawatt increase in its data center pipeline during the second quarter as the artificial intelligence build-out gains momentum.  The California utility’s pipeline of proposed data center projects totaled 12.7 gigawatts at the end of June, up from 5.1 gigawatts in March, the company said Thursday in its latest earnings presentation. The surge underscores that the data-center boom won’t be limited to the states that have dominated AI infrastructure thus far, including Virginia and Texas.  The utility separates projects in the pipeline into different categories depending on how far along the interconnection application is. The current makeup of the pipeline shows that while dozens of projects have advanced enough to sign an application and pay a study fee, far fewer are close to getting connected. … ”  Read more from the San Jose Mercury News.

California can’t replant its forests fast enough to keep up with wildfires

“A windowless warehouse on the outskirts of Davis shelters pieces of California’s forests.  Icy air swirls and fogs around 42,000 pounds of seeds — the past and the future of these trees, frozen in cardboard boxes. It smells like the woods on a snowy day.  “This is like the mothership of forestry in California right here,” said Stewart McMorrow, staff chief for wildfire resilience at Cal Fire, standing outside the heavy metal door of the state seed bank at Cal Fire’s Lewis A. Moran Reforestation Center in Davis.  Private landowners especially rely on these seeds — some now more than a half-century old — to reforest property destroyed by wildfire.  At the pace California is burning, it’s nowhere near enough.  Climate change and more than a century of overzealous fire suppression are now fueling wildfires so severe that they’re wiping out the very forests that need fire to thrive — leaving iconic landscapes at risk of turning into brush and scrub, permanently.  Over the past quarter century, high-severity wildfires have burned 2.3 million acres of California’s forestland so completely that the trees are unlikely to return on their own — according to a working draft of the state’s new reforestation strategy obtained by CalMatters. … ”  Read more from Cal Matters.

Controlled burns have saved thousands of giant sequoias

“The use of small, controlled burns to clear out flammable underbrush has saved thousands of giant sequoias from devastating wildfires, new research finds.  The largest trees on Earth, sequoias can reach more than 300 feet tall and live for 3,000 years, but they grow only in a narrow band of the Sierra Nevada mountains in California, where hotter, drier weather has left forests increasingly prone to wildfires. With their thick bark and high canopies, the trees can withstand small fires, but the more intense blazes seen in a warmer climate have proved deadly for thousands of trees.  Together, the 2020 Castle Fire and 2021 KNP Complex Fire killed as many as 13,000 giant sequoias, or close to a fifth of all sequoias. According to the new study, the death count would have been considerably higher without the use of prescribed burns. … ”  Read more from Yale e360.

Why only a few wildfires become extreme

“Hot and dry conditions have become synonymous with the risk of extreme wildfires. But a new paper argues that such conditions are not by themselves sufficient for blazes, and most warm years do not result in the burning of exceptionally large areas.  The reason is that extreme fires — the few percent of fires that grow rapidly, keep spreading, and end up accounting for nearly all of the area burned — need brief-lived windows of opportunity: an unusual confluence in which winds, terrain, dry vegetation, and ignition coincide. Warm, dry conditions can prime broad regions for burning, but only certain weather setups allow a fire to grow rapidly and keep spreading. These conditions vary from one region to another and may last only a few days.  Understanding such windows of opportunity is critical, according to the paper. Wildfire activity is dominated by rare events. Only a small fraction of fires grow large, and yet that small fraction accounts for nearly all of the area burned. … ”  Read more from NCAR.

Steve Hilton says California must end California’s “war on agriculture”

“California’s agricultural industry has long been recognized as one of the world’s most productive food-producing regions, but according to California gubernatorial candidate Steve Hilton, state government has spent years making it increasingly difficult for farmers and ranchers to succeed.  During an extensive interview with Nick Papagni, “The Ag Meter,” Hilton laid out his vision for California agriculture, discussed his campaign for governor, and shared why he believes restoring support for farming should be one of Sacramento’s highest priorities. Throughout the conversation, Hilton also addressed affordability, water policy, energy, infrastructure, government spending, and what he believes must change if California hopes to remain competitive. … ”  Read more from AgNet West.

The valley water built

Geoffrey Vanden Heuvel, Director of Regulatory and Economic Affairs at Milk Producers Council and Vice Chair of the Water Blueprint for the San Joaquin Valley board, writes, “To most Californians, the San Joaquin Valley is farmland and freeway: the flat stretch of Interstate 5 or Highway 99 between the Bay Area and Los Angeles, crossed on the way to somewhere else.  But the farmland and the food it produces are only what the Valley is famous for. It is not the whole of what the Valley is.  Those drivers are passing one of the youngest and fastest-growing regions in California, home to more than four million residents, a population larger than half the states in the union, with an under-35 majority that is the workforce California is counting on for the next fifty years.  And that workforce is being educated here, at scale, by institutions the drive-through story never mentions. California’s first chartered university has called Stockton home for a century. Fresno State currently ranks fourth in the nation for moving students up the economic ladder, and it shares the Valley with Stanislaus State and CSU Bakersfield in a university system that leads the country in social mobility. A UC campus in Merced, opened in 2005, reached the top tier of American research universities in under twenty years. A network of community colleges is strung along the entire length of Highway 99, putting higher education within a short drive of nearly every Valley family. … ”  Read more from the Water Blueprint for the San Joaquin Valley.

California’s data center backlash is loud—and deeply misplaced

Opinion writer Tom Philp writes, “More than 100 recent protests across California and the U.S. over data centers represent the same fierce opposition that horse enthusiasts once mounted against Model T cars. The times eventually change. And so, in the end, do we.  Today, talk of a new data center brings home how artificial intelligence is wrongly changing our future. The physical embodiments of this rapid evolution are the buildings with the humming servers that are increasingly tapping precious supplies of electricity and water. We are worried about the wrong thing. California in particular is much more likely to successfully manage the resource demands of artificial intelligence than the technology itself. Trying to stop the demand for any given new data center is as meaningful as trying to thwart a meteor with a squirt gun. … ”  Read more from the Sacramento Bee.

VIC BEDOIAN: Feds Fail to Protect Endngered White Sturgeon

White Sturgeon are the largest freshwater fish in North America and an ancient species that once thrived in the San Francisco Bay estuary. Now they’re in decline. Federal officials announced Tuesday that although the White Sturgeon meets the criteria for endangered status, the government will not take any action to save it. The endangered species finding was compelled by a lawsuit filed in 2023 by San Francisco Baykeeper and other environmental advocates. Vic Bedoian reports from Fresno.

ECONEWS: Trump attacks the California Coast

The Trump Administration is going after California’s coast. To curb California’s power to stop harmful development off of its coast, NOAA has announced a new review of the California Coastal Management Program. The program is California’s way of implementing the Coastal Zone Management Act and allows more power for California to review and check federal projects off our coast. While NOAA conducts routine, periodic performance reviews of state coastal programs, it appears that this is deliberately to strip power from the state in order to advance more oil and gas developments and “space port” developments desired by Trump acolytes like Elon Musk.

Mexico and US team-up to build desalination plant in Baja

“Mexico says it’s finally going to hire a company to build a plant that turns the ocean into freshwater in Rosarito, reviving an idea shelved years ago amid protests that the government was privatizing water.  And, in the name of reducing how much water Mexico takes from the Colorado River, the United States is going to help get the water to the cities that need it. Construction could start as soon as Aug. 1, according to a federal Mexican project website, but the government had not yet selected a builder.  Mexican President Claudia Sheinbaum’s administration announced plans to restart the building of the desalination plant in May 2025. But multiple attempts by the Sheinbaum administration to secure a private builder have failed.  In March, the North American Development Bank – a special bank created by the United States and Mexico to pool equal shares of investment for infrastructure projects – announced it would lend Mexico up to $114 million to build and reinforce the pipes and pumps the plant needs to get water to rapidly-growing urban cities in Baja California.  Treated ocean water, the bank says, would replace some of the Colorado River water Mexico is entitled to under a treaty with the United States. … ”  Read more from the Voice of San Diego.

“DRI and OpenET are partnering with the Upper Colorado River Commission and the Bureau of Reclamation to expand evaporation monitoring on the Upper Colorado River Basin’s largest reservoirs. This summer, new monitoring stations are being established on Flaming Gorge, Blue Mesa, and Navajo Reservoirs. The initiative follows the success of the Lake Powell evaporation monitoring project – one of the longest-running reservoir evaporation monitoring efforts in the Western U.S., which has provided data since 2019. Establishing state of the art weather and evaporation monitoring stations at these reservoirs will directly inform improvements for evaporation models and our understanding of water availability in the Colorado River. … ”  Read more from the Desert Research Institute.

APS to convert Cholla power plant from coal to natural gas. It expects water usage to be the same

“Earlier this month, APS announced that it plans to convert its Cholla coal plant to natural gas by 2029. While APS says it will reduce emissions, the utility expects water use to be about the same.  Natural gas plants are often touted for using less water than their coal counterparts.  A report from the U.S. Energy Information Administration found that, on average, natural gas water usage was about seven times lower than coal. … ”  Read more from KJZZ.

Salt Lake City wants to limit nonresidential water use to 200,000 gallons daily

“Utah’s capital city approved an emergency measure earlier this year to crack down on the amount of water new nonresidential developments use daily.  The measure complicated the federal government’s desire to build an immigrant detention center on the city’s west side at the time, but the city could strengthen those restrictions as its leaders look to permanently include the measure in code.  Salt Lake City is considering a new ordinance that would limit new nonresidential properties to 200,000 gallons per day, mirroring the emergency order issued in March. Uses tied to agriculture would be exempt, as would water consumed by schools, government-owned or operated facilities that primarily provide social services, places of worship and hospitals. … ”  Read more from KSL.

Colorado basins supplying 70% of Lake Powell’s water face major midcentury shortages

“If the Colorado River Basin is the lifeblood of the American Southwest, keeping the region’s agricultural, ecological and economic systems thriving, Colorado’s West Slope River basins could be considered the heart. Together, they contribute about 70% of the water delivered to Lake Powell, the second-largest reservoir in the nation.  A new Cornell study, the most extensive of its kind, shows how drivers of water shortages, from melting snowpack to growing population demands, may affect this collective of six basins and Lake Powell—a major source of energy and water supply for 40 million people that has been in the grip of severe drought for the past 20 years.  One of the region’s most significant challenges, the study finds, is a potential 50% drop in the West Slope basins’ inflows to Lake Powell over the next several decades. The findings are published in Earth’s Future. The lead author is postdoctoral researcher Sai Veena Sunkara. … ”  Read more from PhysOrg.

Nearly 460 miles of rivers in Colorado under fishing restrictions as a result of heat and drought

“The small town of South Fork, Colorado, is named for a tributary of the Rio Grande River, which joins with the main river in the middle of town. This stretch of the Rio Grande is labeled a “Gold Medal” fishery by the state, meaning flyfishers have a better chance of catching more and bigger trout. It’s typically a prime destination for late afternoon casting right in sight of the nearby golf course.  Not this summer.  The Rio Grande River running through the town of South Fork is about 87% lower than normal for this time of year. Those trickling flows and well above normal water temperatures have led Colorado Parks and Wildlife to place a voluntary fishing closure on 74 miles of the Rio Grande from noon until midnight. … ”  Read more from Colorado Public Radio.

Colorado’s largest wildfires this summer could cost a quarter billion dollars, early estimates show

“The costs of Colorado’s summer wildfires are racking up.  It could cost taxpayers about $266 million to cover the response, suppression and recovery for the state’s four largest fires this summer according to a developing 90-day cost projection, state officials said during Thursday’s Drought Task Force meeting.  “The financial impacts on things that cascade from drought impacts and so forth are tremendous,” Chris Sorensen with the state emergency operations center told the task force. “In light of cutting $2.5 billion out of the state’s budget over the past 15 or 18 months, that’s a very notable number.”  The costs extend beyond finances to lives lost, homes destroyed and communities disrupted, Sorensen said. Four Colorado wildfire responders died fighting the fires. Hundreds of Coloradans lost homes.  “The impacts are widespread, and all interrelated,” he said. “We’ve heard so many things, but let’s keep in mind all of those impacts, including the lives that are lost.” … ”  Read more from the Colorado Sun.

Water is one of four fronts in Interior’s AI push

“On Wednesday, July 22, the U.S. Department of the Interior described the part it plays in what the federal government calls the Genesis Mission.   The Genesis Mission is a government-wide effort led by the White House Office of Science and Technology Policy. According to the Interior Department, it uses artificial intelligence to speed up scientific discovery, strengthen American energy production and support national security.  Artificial intelligence, in this setting, is not a chatbot. It is software trained on enormous piles of measurements so it can spot patterns and make predictions faster than people can. That software needs raw material. Interior says it holds a great deal of it. … ”  Read more from Western Water.

Interior releases major update on coal potential beneath federal lands

“The Department of the Interior today released a U.S. Geological Survey report on coal resources beneath federally managed public lands in the United States, estimating that there are 4.2 billion short tons of reported coal reserves associated with active mines and an additional 356 billion short tons of available coal resources.   If produced, that would be enough coal to supply all the nation’s needs for at least 600 years at the current rate of consumption.   “American Energy Dominance is more important than ever, and so is beautiful clean coal’s role in the production of electricity needed to fuel our future prosperity,” said Secretary of the Interior Doug Burgum. “Thanks to the USGS’s rigorous and independent assessment, we’re better equipped to manage America’s vast public lands responsibly while supporting energy security and economic opportunity.” … ”  Read more from the Department of the Interior.
