“Fall has arrived in California. After a scorching summer with temperatures climbing above 100 degrees, nearly 70% of California is now experiencing either abnormal dryness or drought, according to the latest date from the U.S. Drought Monitor. The return of dry conditions marks a sharp shift from earlier this year.  In January, none of California was experiencing drought conditions, marking the first time in 25 years that the state had been completely drought-free, according to the U.S. Drought Monitor. Months of hot, dry summer weather have since erased that milestone. … ”  Read more from the Sacramento Bee.

Whether it’s ‘super’ or ‘Godzilla,’ El Niño is already breaking records

“By now, you’ve seen the headlines, and there’s more of them every day: It’s “jaw-dropping.” It’s poised to make global warming worse. California has just declared a statewide state of emergency. This year’s El Niño — a shift in Pacific Ocean trade winds that scrambles global weather patterns — has been hotly discussed as one of the strongest on record, and one that could bring about potentially disastrous consequences. One study projects that it may cause as many as 451,000 heat-related deaths around the world by February.  The current El Niño has also been given an array of eye-catching descriptors. When Jeffrey Shaman, a climatologist at Columbia Climate School, heard the phrase “super El Niño” for the first time earlier this year, he said, “I literally googled it.” The phrase isn’t officially used by the National Oceanic and Atmospheric Administration or the World Meteorological Organization. But he still sees value in the label as a way of communicating the significance of this year’s likely unprecedented El Niño to the general public.  “It’s colloquial, and there’s nothing wrong with that at all,” Shaman said. … ”  Read more from Grist.

California’s largest new water storage project takes a major step forward

Proposed location of Sites Reservoir

“During Climate Week, Governor Gavin Newsom today announced that Sites Reservoir — one of the biggest water projects in modern state history — is moving closer to construction. Late last week, the Sites Project Authority moved the project forward, signaling that a revised water right permit from the State Water Resources Control Board can support a viable reservoir project. This moves the project forward into an investment period, which puts the project closer than ever to construction,” said Governor Newsom.  “Next, the final permit will go before the State Water Board on November 4.  “California is moving with urgency to build the water infrastructure our changing climate demands. Sites Reservoir will help us capture more water when storms bring it, store it for when communities, farms, and the environment need it most, and strengthen our resilience to drought, floods, and a changing climate. The latest action moves this critical project another major step closer to construction.” … ”  Read more from the Office of the Governor.

Solano County Supervisors put spotlight on Delta, its diversity

“The Solano County Board of Supervisors this week recognized Sept. 20-26 as Sacramento-San Joaquin Delta Week.  Supervisor Wanda Williams noted that about 12 million individuals visit the Delta each week. She said the Delta is home to 500,000 acres of agricultural land that provides food for worldwide distribution, provides habitat for 750 species of animals and plants and provides a portion of water to about 27 million Californians.  The recognition was established in 2022 by then state Sen. Bill Dodd.  “The Delta is vital to our state as both a natural resource teeming with abundant wildlife and fish and a vital economic driver for tourism, recreation and Delta farmers. It is a cherished watershed and the very lifeblood of California’s water system. We must continue to protect it for future generations by preventing pollution and further marshland degradation and promoting its environmental health,” Dodd said at the time. … ”  Read more from the Daily Republic.

Report shows major progress in California on preparing for wildfire

“California is bringing a simple message to Climate Week NYC: Climate action means protecting people where they live.  In California, that means reducing the threat of catastrophic wildfire. It means making forests healthier. It means giving firefighters more time and better tools to protect homes and communities.  Governor Gavin Newsom today highlighted a new report on California’s work to reduce pollution and the risk of catastrophic wildfire while protecting California communities and lands. Over five years, California trained hundreds of firefighting personnel, prepared thousands of acres to resist wildfire and prevented smoke and millions of metric tons of carbon from entering the air. … ”  Read more from the Office of the Governor.

He knows his community is going to burn again. Now he’s making sure they’re ready

“As the Lucas Fire tore through Mendocino and Lake Counties, two portable fire hydrants sprouted from Lake County’s Keeling Park, pumping water directly from Clear Lake.  It was the first test of a homegrown solution to a problem the state is only beginning to reckon with: water systems never built to fight climate-fueled wildfire, with no specific guidance, mandate or funding to adapt.   Wildfires have burned roughly two-thirds of rugged, remote Lake County in less than 15 years — straining already overburdened water systems. So when lightning struck and the Lucas Fire sparked, Chief Shannon Banks of the Northshore Fire Protection District called local water companies to set up the new hydrants.  “We always in the past have looked for alternative water sources,” Banks said. “These pumps just make it a lot easier.” … ”  Read more from Cal Matters.

Fast, severe wildfires can change how forests grow back

“Climate change–driven drought is making wildfires larger and more frequent. A new analysis of nearly 3,500 recent wildfires in the western United States and Canada showed that when a fire spreads swiftly, it will burn a larger area and more of that area will be severely burned.  What’s more, the faster a fire spreads, the greater will be the distance between severely burned trees and living seeds that could regrow them is. This distance suggests that forests might not grow back the same after a fast, severe wildfire, opening the door for significant and unpredictable ecosystem changes.  “We are experiencing in many settings fire regimes that are completely outside of the box as to what those forests evolved with and are adapted to,” said Jonathan Coop, an ecologist at Western Colorado University in Gunnison and lead researcher on the project. “This is the context in which we are observing postfire ecosystem trajectories that are leading in very different directions than a return to the prefire forest type.” … ”  Read more from EOS.

Ducks Unlimited on why Healthy Rivers and Landscapes works for waterfowl, wildlife and California

“Each winter, millions of waterfowl travel the Pacific Flyway, one of North America’s major bird migration routes, relying on California’s wetlands, rivers and working lands to rest and refuel along the way. The Sacramento Valley is especially important, providing critical wintering habitat for waterfowl along the Flyway.  For Jeff McCreary, Director of Operations for Ducks Unlimited’s Western Region, protecting this migration “superhighway” illustrates why water management in California must consider the connections between rivers, wetlands, working lands, fish, wildlife and communities.  It is also why Ducks Unlimited supports the Healthy Rivers and Landscapes (HRL) program. … ”  Read more from the Northern California Water Association.

Protecting California’s coastal waters helps heal the ocean — and its tribal caretakers

Eva Pagaling, a community member of the Samala, the Santa Ynez Band of Chumash Indians and the Yakama Nation, writes, “My path to advocating for ocean protection began when I was about 10, watching my dad and other Chumash community members build our traditional maritime tomols, or canoes, using redwood planks and yop, the tar and pine pitch.   Our tomols link generations of our people, who have paddled and fished in our ancestral waters off California’s Central Coast for millennia. From San Luis Obispo to Malibu and the Northern Channel Islands, our people have fostered a reciprocal relationship that has sustained thriving marine ecosystems.  Colonization nearly severed our maritime traditions, beginning with the forced removal of our people from our islands and coasts.  During the 1800s, our ancestors were enslaved to construct the California mission system. That led to the padres burning all our tomols, an act of ethnocide intended to break our spiritual and physical ties to the ocean. … ”  Read more from Cal Matters.

Is the Humboldt County coast ready for king tides, storm surge, and super El Niño this winter?

“With water already running about a foot higher than usual in Humboldt Bay and a powerful El Niño strengthening offshore, North Coast residents could see a winter where several coastal threats may arrive at once. Forecasters say king tides, Kelvin waves, unusually warm ocean waters, and stronger storm systems could combine, leading to flooding and erosion in low‑lying neighborhoods such as King Salmon and Fields Landing.  In two months, the California coastline will be impacted by king tides, higher waves that usually arrive around the end of the year. The Times-Standard reached out to several government agencies to see how they are preparing for the next potentially catastrophic event. … ”  Read more from the Eureka Times-Standard.

Building momentum the focus for Nature-Based Solutions Forests and Mountain Meadows Summit

“In its efforts to combat the impacts of climate change and help protect communities and landscapes from extreme weather events, such as wildfires, the state is harnessing one of its greatest powers: Nature.  Since 2020, California has invested billions in funding to advance nature-based solutions – projects that restore health and resilience to the land to protect natural resources and communities while also durably storing carbon. These projects come in many forms, such as removing overly dense fuels from forests, using beneficial fire to prevent more damaging wildfires, restoring mountain meadows, and replanting forests after a high-severity wildfire. By working with nature, these efforts strengthen ecosystems while also helping landscapes adapt to a changing climate.  To build momentum around efforts to advance these critical solutions and celebrate initial progress, the California Natural Resources Agency is organizing a series of NBS summits across the state. The California Natural Resources Agency, Sierra Nevada Conservancy, California Tahoe Conservancy, and The Nature Conservancy hosted one of these summits focused on forests and mountain meadows in Tahoe City on Thursday, Sept. 10. … ”  Read more from the Sierra Nevada Conservancy.

Volunteers invited to help restore a meadow for 29th annual Tahoe Forest Stewardship Day

“On Saturday, September 26, Keep Tahoe Blue and the Tahoe Resource Conservation District will welcome volunteers of all ages and skill levels to participate in fun, hands-on projects to help restore Johnson Meadow in South Lake Tahoe to a healthier, more resilient ecosystem that protects Lake Tahoe’s famous water clarity.  Guided by restoration professionals, volunteers will stabilize the banks of the Upper Truckee River and restore vital meadow habitat. Tools, training, and lunch will be provided. No experience is required to participate. The volunteer event is part of a larger, multi-year restoration effort at Johnson Meadow.  When they are healthy, Tahoe’s forests, meadows, marshes, wetlands, and streams act as natural filters, removing polluting particles from flowing water before they reach the Lake itself. These filters also improve Tahoe’s climate resilience, so the Lake can better withstand extreme weather, fire, drought, and other impacts of a changing climate. … ”  Read more from South Tahoe Now.

Why Colorado’s largest natural lake remains full despite drought

“Grand Lake, Colorado’s largest natural lake, remains filled to the brim this summer while reservoirs across the state sit low.  A federal law passed nearly 90 years ago requires it to stay full so it can carry water to the Front Range.  Colorado’s reservoirs are about 60% full on average, a result of extreme drought and last winter’s historically low snowpack. Marinas elsewhere have watched their docks settle onto dirt. Neighboring Lake Granby is at 53% of capacity.  The 389-foot-deep Grand Lake is different. Nearby reservoirs pump water into it, and gravity then moves that water through a 10-foot pipe toward the east. Grand Lake Town Manager Steve Kudron said the water serves more than 1.5 million people, including Estes Park.  Senate Bill 80, passed in 1939, established the lake as a conveyance for moving water to the Front Range.  “This lake will actually never change beyond 6 inches,” Kudron said. … ”  Read more from Denver’s Channel 9.

America’s water systems face a growing cybersecurity threat

“America’s water systems are increasingly in hackers’ crosshairs. In recent years, dozens of water utilities experienced cybersecurity attacks that forced them to take systems offline, operate manually, or suspend billing or customer account services. Over just a few days this past July, the FBI received reports of cyber incidents affecting water systems across at least seven states.  Although most incidents have not contaminated water or caused sustained outages, cyber threats are increasing as more utilities adopt internet-connected technologies—often without appropriate safeguards. Preventing, responding to, and recovering from cyberattacks can impose significant costs on utilities, including for cybersecurity training and staff, vulnerability assessments, and software and equipment upgrades.  “Things that even 10 years ago we never thought about are all now adding to the cost of what it takes to run a water supply system,” said Mike Grimm, vice chair of the American Water Works Association’s Water Utility Council, earlier this year. … ”  Read more from Governing.
