Here comes El Nino: It’s early, likely to be big, sloppy and add even more heat to a warming world

“An early bird El Nino has officially formed, likely to be strong, warp weather worldwide and give an already warming Earth an extra kick of natural heat, meteorologists announced.  The National Oceanic and Atmospheric Administration Thursday issued an El Nino advisory, announcing the arrival of the climatic condition. It may not quite be like the others.  It formed a month or two earlier than most El Ninos do, which “gives it room to grow,” and there’s a 56% chance it will be considered strong and a 25% chance it reaches supersized levels, said climate scientist Michelle L’Heureux, head of NOAA’s El Nino/La Nina forecast office.  “If this El Nino tips into the largest class of events … it will be the shortest recurrence time in the historical record,” said Kim Cobb, a climate scientist at Brown University. … ”  Read more from the Associated Press.

DWR and partners experiment with soft release method to improve Delta smelt survival

DWR Environmental Scientist Trishelle Temple releases Delta smelt into a cage as part of an experimental soft release. The fish acclimate in the cage for 48 hours before being released into the Sacramento Deep Water Ship Channel. Photo by DWR.

“Delta smelt are a fish that have gone from vast abundance to the brink of extinction. After seeing some positive results with releasing hatchery-raised Delta smelt into the wild in 2022, the Department of Water Resources (DWR) and partners are now experimenting with hard and soft release methods to see if there is a chance for even greater success and improved species survival.  DWR Senior Environmental Scientist Trishelle Tempel explains the difference between the two methods.  “In a hard release we essentially load the fish up and put them directly in the river, but in a soft release we take those same fish and put them in an enclosure and that gives them time to get used to their surroundings, maybe slow down some of their stress levels, and hopefully prepare them for better success when they get out into the water,” Tempel said. … ”  Read more from DWR News.

Improved passage lets threatened sturgeon, salmon and other species return to spawn in Sacramento River

“Dozens of adult sturgeon and hundreds of other large fish including threatened Chinook salmon have moved safely from receding floodwaters within the Yolo Bypass back to the Sacramento River thanks to the coordinated operation of the Fremont Weir Adult Fish Passage among the California Department of Water Resources (DWR), the California Department of Fish and Wildlife (CDFW), NOAA Fisheries and Yolo County.  Over one 48-hour period when the Fremont Weir Adult Fish Passage was opened on April 28 and 29, the facility’s fish-counting sonar counted 55 sturgeon passing through the facility to the Sacramento River to migrate upstream and spawn. Sturgeon are large fish that often measure 6 to 7 feet long and certain species can live over a century. They must reach the river to spawn, which they do only every few years.  In another 24-hour window between May 3 and 4, seven more sturgeon passed through the facility. Hundreds of other large fish and Pacific lamprey were also counted moving back to the Sacramento River during the two operational windows in April and May. … ”  Read more from CDFW.

“Seizing the opportunity from an extremely wet winter and spring to boost groundwater levels, the State Water Resources Control Board since late December 2022 has authorized the diversion of 1.2 million acre-feet of water – more than enough to fill the Folsom Reservoir – for underground storage, wildlife refuges and other purposes.  “Planning for future dry conditions is critical to protecting our communities, health, and our environment,” said California Secretary for Environmental Protection Yana Garcia.  “The state has taken unprecedented action to leverage the benefits of our recent wet weather by replenishing our groundwater resources through recharge, and we look forward to achieving even more progress in the future with partners across the state. This is just one example of how our state is creating a more resilient water supply for all Californians in the face of climate-driven weather extremes.” … ”  Continue reading from the State Water Resources Control Board.

Lake Oroville approaches the top

“The water level at Lake Oroville has approached “the top” at 899 feet elevation for the second day in a row on Wednesday.  The last time the lake approached full capacity in the spring was in 2012, according to an email from DWR information officer Jason Ince.  Ince said there are no plans to test the emergency spillway, but there will be potential for waves to splash over the crest if the weather is particularly windy. He said wave splash will not affect the integrity of the spillway structure or dam.  Employees dressed in yellow safety vests were seen by the spillway Wednesday and were conducting a regularly scheduled inspection that began Monday, Ince said.  The lake’s elevation reached 890 feet on May 13 and has been climbing up to 899 since then. Water will flow over the top of the emergency spillway’s weir at 901 feet elevation, should the lake rise that high. … ”  Read more from the Chico Enterprise-Record.

How indigenous and environmental coalitions pushed for beaver restoration in California’s budget

“It’s taken years of drought and intense wildfires for California officials to recognize that the state’s current water management system is underprepared to meet the needs of its changing climate. For many wetland conservationists, water managers, and especially California Indigenous water protectors, one solution has always been at hand—bring in the beavers.  New state funding is boosting a restoration program to help relocate beavers to areas in need of wetland conservation. This is one of the many efforts legislators and state departments are now focusing on to advance climate resilience—and will reveal how beavers are beneficial, not detrimental, to California’s waters and lands.  “They are the best engineers that we could possibly hire in order to help us with watershed management, and we need them, for many reasons,” says Sherri Norris, the executive director of the California Indian Environmental Alliance, a nonprofit coordinating 34 California tribes working toward environmental action and justice. “[Beavers] are a part of the natural landscape, they align with the governor’s 30×30 plan, and they are a part of nature-based solutions.” … ”  Read more from Non Profit Quarterly.

Wild horse deaths in California Sierra show a delicate ecosystem off balance

East of Yosemite national park, Mono Lake is an ancient body of water, home to millions of brine shrimp and waterfowl and providing stunning views. It’s also home to a herd of more than 500 wild horses that began arriving in the area around 2015.  This spring, as snow drifts from a record-setting winter storm began to melt, officials were surprised to find the horses turning up dead.  “Visitors should be prepared to come across horse carcasses and manure,” officials with the Inyo national forest posted on Facebook in mid-May, saying there had been reports of “several horse carcasses” around the lake, accompanied by unsettling photos of skeletal remains.  Experts believe the harsh winter conditions are likely behind the deaths, putting a spotlight on the precarious relationship between the horses and this rugged landscape – both in terms of the dangers it poses to them, and the dangers they pose to it. … ”  Read more from the Guardian.

New report highlights how to finance green infrastructure establishment costs

“The Environmental Policy Innovation Center and WaterNow Alliance’s new report, Navigating Green Infrastructure Maintenance with Capitalized Establishment Costs, offers a key pathway to scaled investment in green infrastructure. For two decades, local stormwater managers have recognized green infrastructure (GI) as an effective, multi-benefit approach to manage stormwater. GI provides significant benefits for combating the water quality and climate change related challenges that municipalities face. In addition, GI is a centerpiece One Water strategy; it can capture and reuse stormwater to enhance water supply reliability, creating resilience to drought. Beyond these water management benefits, GI generates community and economic co-benefits including local green jobs, among others. Yet, GI has mostly remained on the fringes of stormwater management. A “nice to have” amenity. It makes up only 10% of stormwater management organizations’ expenditures and only 3% of the Clean Water State Revolving Fund’s investments.   To realize its potential and have a substantial impact for communities, GI needs to scale up. … ”  Continue reading at Water Now.

Researchers find why San Andreas fault hasn’t caused a big earthquake in L.A. — yet

“The southern San Andreas fault in California is in a seismic drought, going more than 300 years without a major earthquake.  New research shows the lack of seismic activity may be due to the drying of the nearby Salton Sea and provides clues on future potential earthquake triggers, including projects aimed to refill the body of water.  One of the largest faults in the world, the 800-mile-long San Andreas marks the meeting of the North American and Pacific plates in western California. The fault has three sections, but the southern section from the Salton Sea to Parkfield, Calif., has been historically the quietest — and that’s not a positive. The pent-up energy, when released, could be catastrophic to nearby populated cities.  The new study, published Wednesday in Nature, investigated earthquake activity along the southern San Andreas fault over the last 1,000 years. Collecting field data from rocks near the fault, Hill and his colleagues found earthquakes occurred about every 180 years, give or take 40 years, and coincided with high water levels of the nearby ancient Lake Cahuilla. …  ”  Read more from the Washington Post (gift article).

Commentary: California needs smart water policy, guided by data

Justin Fredrickson, a water and environmental policy analyst for the California Farm Bureau, writes, “Advocates for California agriculture have had quite a bit to say about the state’s maddening failure to capture more water in wet years when it’s available. We have also expressed related concerns about fixing the burdensome water rights permitting process, which can begin to correct some of this problem.  Despite legislative and administrative attempts to authorize temporary 180-day and five-year permits to allow harvesting floodwater to recharge depleted groundwater supplies, few permits have been secured. The timing of approvals is also often out of sync with the timing of available water.  A March 10 executive order by Gov. Gavin Newsom during the atmospheric storms made it easier for agricultural landowners to divert excess water to recharge aquifers and reduce flooding dangers. It was a major step, yet the long-term process needs to be further streamlined for a durable solution. … ”  Read more from Ag Alert.

The Tulare Basin represents the wrong approach to flood planning

Sacramento Bee opinion writer Tom Philp writes, “When it comes to flood protection in the San Joaquin Valley, it is a tale of two stories. In most of the San Joaquin River watershed, where the state and locals work together year in and year to better protect the region. And then there is where it is now flooding, the Tulare Basin, which has preferred to be left alone. There is an explanation, involving the state’s unofficial king of the Boswell lineage. The Legislature in 2008 declared that for San Joaquin Valley flood planning purposes, the Tulare Basin, which is spans parts of Tulare and Kings counties between Stratford, Corcoran and Kettleman City, is simply not in the San Joaquin Valley. … ”  Read more from the Sacramento Bee.

FEATURE: Water rights key to San Joaquin Valley aquifer recharge

Written by Robin Meadows

It sounds like such a simple fix for California’s groundwater woes. In phenomenally wet years like this one, when reservoirs are so full water is still being released to make room for snowmelt, just use some of that liquid wealth to inundate agricultural lands above severely overdrafted aquifers.

But nothing is simple in the world of California water. This approach, called managed aquifer recharge, has a host of complications including sorting out who has rights to floodwaters, how to allocate those rights equitably, and whether plans for securing those rights for recharge are realistic.

Many of us also spend long hours commuting over or along this tidal estuary, regularly viewing its waters from the bridges above. It’s easy to take the Bay for granted — but what would it mean to lose it?  The Bay is vulnerable to the accelerating impacts of climate change, but as the world warms, it’s also becoming a looming threat to those who inhabit its low-lying shores. Sea levels are projected to rise, putting many shoreline communities at risk of inundation. Algal blooms are expected to return with greater frequency as temperatures warm. Marine heat waves and ocean acidification are accelerating, posing threats to Bay waters and coastal ecosystems. And invasive species, like the European green crab, are on the rise, boxing out native species and altering the ecosystems that give San Francisco Bay its unique character. … ”  Read more from the Nob Hill Gazette.

Cows help reduce wildfire risk, restore native habitats in eastern Orange County

“Among climate advocates, beef typically gets a bad rap.  To stock feedlots for factory-farmed cattle, which is how 70% of America’s cows are raised, crews often clear forests and use lots of water to grow grain. And once those cows eat, their burps and flatulence and decomposing manure emit high levels of planet-warming greenhouse gases.  Even grass-fed cattle are sometimes allowed to graze in one area too long, or return to the same area too frequently, turning grasslands into virtual deserts.  But pilot projects underway in eastern Orange County are offering up some promising evidence that suggest carefully planned cattle grazing might actually help restore native plant and animal life while also reducing wildfire risk. … ”  Read more from the OC Register.

Water supplies for homeowners and businesses are protected. Growth has been planned for and will continue. My message to Arizonans is this: we are not out of water, and we will not be running out of water.” … ”  Read more from the Arizona Chamber Business News.

Boulder County cities and towns pursue solutions to future Colorado River shortages on their own

“This winter dropped a lot of snow on the mountains above Boulder. Our reservoirs are in good shape for now as Boulder Creek babbles. But that’s not our only water source.  Boulder and many other cities along the Front Range rely, at least in part, on water from the strained Colorado River. Younger cities with fewer senior rights for local water sources — like Superior and Erie — rely on it almost entirely.  Because every city is responsible for its own water portfolio, as the Colorado River becomes a potentially unreliable source, wholly dependent cities could be far worse off than others. This isn’t a far-fetched idea. A Colorado State University study shows that for every degree Fahrenheit of global warming, flows of the Colorado River decrease by 4%. And already, the Windy Gap Project — responsible for supplying a portion of Colorado River water to Front Range cities — sometimes doesn’t provide any water at all. … ”  Read more from KUNC.

National dam safety practices reviewed in tri-agency report

“The results of a yearlong study by an independent external peer review panel to assess the use of risk-informed dam safety practices is now available to the public. The verdict – the way the nation operates its dams across three federal agencies is appropriate and sound but can benefit from some areas of improvement.  The U.S. Army Corps of Engineers (USACE), alongside the Federal Energy Regulatory Commission and the Bureau of Reclamation, contracted with a panel of dam experts, all external to their agencies, to review their dam safety practices at the direction of U.S. congress. The review took place following the 2017 spillway failure at California’s Oroville Dam, which triggered broad industry concerns about the safety of dams nationwide. … ”  Read more from the Army Corps of Engineers.
