How long will the record heat wave last in the western U.S.?

“Many areas in the southwestern United States have endured day after day of heat more typical of early summer than early spring. The region will face yet another week of intense heat, but there are signs of a major change before the end of March.  “The heat wave has already lasted five to seven days and appears likely to continue through Friday,” said AccuWeather Vice President of Forecasting Operations Dan DePodwin.  “Phoenix has never experienced more than five days in a row with highs of 100 degrees Fahrenheit or greater during March or April,” DePodwin said. “There are a couple of days with a high near 100 forecast this week, but if temperatures surpass the upper 90s on those days, we could be looking at 10 days in a row of triple-digit heat.”  Many locations from California to parts of Colorado and Texas have tied or broken daily record highs for a long string of days. Some have shattered old records by several degrees. Some have set new early-season high temperature records, wiping out marks set in March and April, even though April is still a week away. … ”  Read more from AccuWeather.

What the surprisingly early heat wave means for California’s summer

“An extraordinary heat wave toppled records this week across the Western United States. In California, it brought the hottest temperatures ever recorded in March.  The final days of winter felt like summer, and across the state, many have wondered what it means for actual summer. If the temperature in Death Valley soared to a record-breaking 104 degrees in the middle of March, would it rise even higher in July?  No one can say for sure in March what the temperature will be in July. Meteorologists can create seasonal forecasts that look several months into the future and estimate whether temperatures will be above or below normal, but those forecasts are not precise. They can’t reliably forecast specific weather beyond seven or 10 days.  But while this heat wave doesn’t dictate California’s summer temperatures, its effects will linger in other ways into the months to come. Here are three of them. … ”  Read more from the New York Times.

California’s warm, dry streak could soon end. Here’s when rain may return

“California’s herky-jerky wet season is at an inflection point.  There has hardly been any rain this month, and the mountain snowpack is melting at a startling rate, which means drought could return by summer.  But the wet season isn’t entirely over.  Weather models are arriving at a consensus: California’s next chance of precipitation will come as March ends and April begins. It’s not a guarantee, as the start of the stormy window is still a week away, but it appears to be the best shot of widespread rain and snow in nearly six weeks.  California hasn’t seen the end of the massive high-pressure system that’s dominated much of the Western U.S. for the past two weeks, driving temperatures up. It’ll stick around for at least five more days and threaten more temperature records in Central and Southern California. … ”  Read more from the San Francisco Chronicle.

As early season heat wipes out Sierra snowpack, can a new approach help California catch more runoff?

“To replenish California’s chronically depleted aquifers, the state’s Department of Water Resources is taking a hard look at a new line of attack: Pairing more sophisticated reservoir operations with groundwater recharge. Water managers are aiming to make greater use of the increased floodwater that’s expected to come with flashier, more intense storms and earlier snowmelt.  The new approach is known as FIRO-MAR, which stands for Forecast-Informed Reservoir Operations-Managed Aquifer Recharge.  In December, DWR released a study focused on the five main tributary watersheds of California’s second-largest river, the San Joaquin, that provides the most comprehensive assessment of the concept’s potential yet. The study suggests that by weaving together better weather forecasts, more-flexible reservoir operations and strategically targeted recharge locations, “FIRO-MAR has the potential to increase the volume of recharge more than fourfold, and it can greatly diminish the size and frequency of flood flows.” … ”  Read more from Western Water.

How do you measure snow from space? First, climb a mountain.

“At 4:30 a.m. on a recent Wednesday, three alpine scientists arose from fitful sleep in a chilly research lab in the Colorado mountains, 11,500 feet above sea level. They drank some grainy coffee, strapped into their skis and headed out into the moonlight, dragging a sled loaded with gear.  They had a satellite to meet.  The scientists were on an unusual mission. They needed to measure the depth of the snow at a particular mountaintop location just as a new satellite passed directly overhead. That satellite, equipped with powerful radar, has the potential to be the first one capable of estimating how much water is on the ground, in the form of fallen snow, from outer space.  It would be an extraordinary technological milestone, providing global data on snowpack, precipitation and how much water might be available to feed rivers and reservoirs downstream in spring and summer. But first, the satellite would need to be calibrated. … ”  Read more from the New York Times.

Five overlooked facts about California’s water supply

Somewhere in the Sierra Nevada. Photo by Vlad Karpinksy.

“California’s vast Sierra Nevada mountains act like a giant sponge that squeeze moisture from the clouds drifting eastward from the Pacific Ocean.  The forests that flank these then mountains capture and filter rain and snow before it reaches streams, rivers and aquifers. Many of our National Forests, which cover more than 20 million acres of the state, are located in higher elevation areas and play a large role in capturing precipitation. California’s National Forests supply 65 percent of the state’s water while occupying only 20 percent of the total land area.  With national attention on California’s record drought, decision-makers and the public are racing to find solutions. While leaders have implemented water conservation measures and engineers are exploring infrastructure solutions, little attention has been given to the source of California’s water – National Forest headwaters. … ”  Continue reading from the National Forest Foundation.

A bit of good news: It’s possible to turn around a groundwater crisis

“Generally, when you hear “water use” and “sustainability,” you expect those words to be followed by some bad news. Humanity’s enduring ability to ignore the math of declining water supplies is almost impressive. But there are cases where actions have successfully reversed our loss of water resources. A new paper in Science by Scott Jasechko of the University of California, Santa Barbara, examines documented cases of groundwater recovery around the world to identify which strategies have worked.  Groundwater is invaluable for many reasons. For one, it’s (usually) cleaner than surface water. It’s also right under your feet and often close enough to the surface that it doesn’t take much energy to pump it up. And there’s loads of it down there, no matter the season. Because of this, humans use a lot of it for drinking water, agriculture, and every other use you can think of. … ”  Read more from Ars Technica.

Environmental group raises alarm over draft approval of California’s Sites Reservoir

Proposed location of Sites Reservoir

“The State Water Resources Control Board on Friday unveiled a draft approval that would advance Sites Reservoir, marking another step forward for what would be the largest reservoir project for California since the 1970s. The draft decision came two months after the Bureau of Reclamation gave the project a green light on environmental review, moving a plan forward that would store up to 1.5 million acre-feet of water west of Colusa County in the Sacramento Valley.  Sites Project Authority, or a joint regional agency behind the project, welcomed the move following the federal approval and reiterated the project would strengthen California’s water supply and protect the environment at the time. With the draft approval, members of the public can submit written comments through May 22. “This draft decision recognizes some of the harms the reservoir would bring but it doesn’t address all of the serious threats to the Sacramento River ecosystem and the imperiled fish populations the project would cause,” said Harrison Beck, an attorney at the Center for Biological Diversity on Monday. … ”  Read more from the Sacramento Bee.

Bill would create an official designation for California’s iconic surf spots

“A Southern California lawmaker hopes to create a new designation for the state’s iconic wave breaks through the creation of “surfing reserves.” Excepting perhaps Hawaii, California’s coastline is home to more world-famous waves than any state. Breaks dot the coast, from renowned Malibu and San Diego beaches to the monstrous Mavericks big wave spot near Half Moon Bay to dozens of lesser known waves (including some consciously kept secret by local surfers) running from the Mexico to Oregon borders. Assemblymember Jacqui Irwin, D-Thousand Oaks, seeks to officially recognize popular breaks, particularly as they face threats from rising seas, coastal erosion and pollution. She’s introduced a bill that would create a process for local governments to designate treasured breaks as “surfing reserves” with the California Ocean Protection Council — a conservation body the Legislature created in the 1970s. … ”  Read more from the Sacramento Bee.

California sues Trump to keep shut oil pipeline on Santa Barbara coast

“California sued the Trump administration Monday to block what it says is an unprecedented power grab: using emergency authority to force the restart of an offshore oil operation shut down more than a decade ago.  The lawsuit, filed in federal court in San Francisco, argues a March 13 order by U.S. Energy Secretary Chris Wright oversteps his authority under the Defense Production Act, a Cold War-era law.  “No matter how much President Trump may claim there’s a so-called national energy emergency — it’s just not true,” Attorney General Rob Bonta told reporters. “The U.S. already produces significantly more oil and gas than we use — it’s a completely fabricated claim intended to curry favor with the oil industry.” … ”  Read more from Cal Matters.

Protecting California’s water – SB 872

Michelle Paul, California Farm Water Coalition, writes, “From the moment California’s earliest residents called the vast, fertile soils of California’s Central Valley home, efforts began to solve one of the state’s oldest challenges: harnessing the water. With rainfall and snowpack varying dramatically year to year, and because most people and farms are in the state’s arid regions, water must be carefully managed and transported long distances to ensure all communities can thrive.  California’s water infrastructure has developed over more than 220 years, beginning with the construction of a stone dam on Mission Creek in 1807. Since then, countless projects have been added to meet the evolving needs of each region. Today, nearly every part of the state’s engineered water supply system is interconnected, either through hydrology or connections between physical infrastructure.  The most obvious examples of this are the federal Central Valley Project and the California State Water Project, mostly built between 1940 and 1979 to meet agricultural, urban, and now, environmental water supply needs. They both share the Sacramento-San Joaquin Delta, and both systems need upgrades and repairs after, in some cases, 80 years of water deliveries. … ”  Continue reading this commentary.

California’s water crisis isn’t a drought—it’s bad policy

Mohamed Moutii, a Research Associate with the Arab Center for Research, a Research Fellow with the Institute for Research in Economic and Fiscal Issues (IREFeurope), and a member of the Ibn Khaldun Initiative for Free Thoughts, writes,  “In late December, winter storms brought rain and snow that modestly improved California’s reservoirs and snowpack. Officials quickly cautioned, however, that this would not solve the water crisis. The message was clear: despite years of restrictions and emergency measures, policymakers still have no path to long-term water security.  California’s water shortages are routinely attributed to drought, climate change, and population growth, while residents are urged to ration water, shorten showers, and accept fines as a civic responsibility. Yet household behavior does not drive scarcity. California’s water shortage is essentially the product of government policy—decades of price suppression, subsidizing waste, and allocating water according to political rules rather than economic value.  Until water is treated as the scarce resource it is—correctly priced and efficiently allocated—no amount of rain or restrictions will fix a crisis of the state’s own making. … ”  Read more from the Daily Economy.

Water tank project faces possible hold as Redway District board meets Wednesday; Planned shutoff March 30

“A dispute over an unpaid subcontractor is threatening to complicate a state-funded water storage project in Redway, according to the board packet prepared for Wednesday’s Redway Community Services District meeting.  Sonoma Reinforcing, a subcontractor that supplied welded rebar cages and HRC T-heads for the project, has filed a stop notice against general contractor Mercer Fraser over an unpaid bill. RCSD Office Manager Glenn Gradin explained in an email that a stop notice instructs the project’s owner, in this case the district, to withhold payment to Mercer Fraser until the subcontractor is paid. If Sonoma Reinforcing isn’t paid, the company could place a lien on the property within 30 days of the project’s notice of completion.  Gradin said the district doesn’t expect it to go that far. “We are confident that we will not be going down this path,” he wrote. “But time will tell.” … ”  Read more from the Redheaded Blackbelt.

Regional partnerships advance Redding-area restoration, community and ecosystem health

“In partnership with state natural-resource agencies, River Partners, a nonprofit river restoration organization based in Chico, is restoring a pair of sites along a critical ecological corridor between Redding and Red Bluff that spans two Northern California counties.  River Partners is leading two projects along the Sacramento River at Battle Creek. The Rancho Breisgau floodplain and Battle Creek Ranch restorations will help boost salmon recovery, wildlife habitat, water resources, and local communities through improved access to nature.  Key partners in the restoration include the U.S. Bureau of Land Management (BLM) and California Wildlife Conservation Board (WCB). River Partners is also partnering with local Tribes, adding to the area’s decades-long legacy of collaborative conservation.  River Partners President Julie Rentner believes that working with a diverse group of partners on these efforts will help guide the work and lead to multi-benefit solutions and positively impact wildlife and communities.  “The Battle Creek watershed is vital for a healthy Sacramento River ecosystem and salmon recovery,” said Rentner. “And this type of partnership in restoring critical landscapes is an absolute win-win for the ecology and will help keep the region thriving.” … ”  Read more from River Partners.

When summer heat arrives in March

“The Bay Area is baking this week. Cue our modern human adaptations to summer: On go the shorts—and the A/C, if we have it. But how are our wild neighbors faring?  A high-pressure system is sitting over much of the West Coast, creating a heat dome: sinking air warms as it compresses and acts like a lid, trapping heat near the surface. The resulting heat wave is by many measures extraordinary, with record temperatures 20–30 degrees above average. Winter is over, and suddenly.  A temperature jolt like this can disrupt the harmonious change of season. If flowers bloom before insects emerge, for example, that could in turn make life harder for the birds that eat those very insects. Such phenological mismatches—a desynchronizing of seasonal biological timing—could stress native flora and fauna. But it might not be so bad in some parts of the San Francisco Bay Area. An absence of drought conditions and a strong maritime layer are likely buffering the region from the most extreme negative effects—though some experts still say they are concerned. … ”  Read more from Bay Nature.

‘Yikes’: Bay Area heat lingers, Sierra Nevada snowpack melting fast

“Although March’s hottest days may be behind us, the unseasonable heat that baked California last week is set to continue, forecasters said Monday. While great for beach goers, the high temperatures threaten to melt the entirety of the state’s dwindling snowpack by the end of the month.  National Weather Service meteorologist Rachel Kennedy wrote in the Bay Area’s daily forecast discussion that while temperatures won’t be as warm as last week’s, they’ll still be about 10 to 15 degrees above normal.  Across inland areas, high temperatures will reach the upper 70s to low 80s through Tuesday, with the 60s to 70s along the coastline. Karleisa Rogacheski, a lead meteorologist with the weather service’s Bay Area office, said temperatures are expected to cool overnight, with morning lows in the upper 40s to mid-50s.  “That’s the story: we are going to bebop around the 70s, it’s going to still be that summer-like pattern,” Rogacheski said. … ”  Read more from KQED.

25 years of change: A quarter century of hard work has restored nature to the San Francisco Bay Area in places where it was once unimaginable.

“When Bay Nature was born 25 years ago, the greater Bay Area stood at a tipping point. Environmental movements of the 1970s had galvanized a core group of people committed to bringing nature back. Thanks to key achievements—the Clean Water Act, the founding of land trusts, new state and federal funding—stinking landfills became parks, and areas once slated for bulldozing were protected.  Now environmental groups had to do something with the places they had saved. “It went from ‘You’re not going to develop this’ to ‘We’re going to restore this,’” says David Loeb, who cofounded Bay Nature with Malcolm Margolin and was its publisher and editor in chief for 17 years. After news-grabbing purchases come far less glamorous years of developing restoration blueprints, applying for permits, cleaning up trash, and rearing native plants. Meanwhile the threats to nature have grown and changed, Loeb says. Development continues to encroach upon natural areas, but climate change now drives much of the restoration work. New invasive species are always arriving. Yet many places have been transformed for the better, and more people are invested in local nature. “It’s not just a specialized cadre,” Loeb says. “You have a whole ecosystem of people now.” … ”  Read more from Bay Nature.

How stormwater studies can make the San Francisco Bay cleaner

“As stormwater sampling across the San Francisco Bay Area reveals more poorly regulated chemicals, those who want clean water in the Bay face a tricky question: what can be done about it?  A raindrop falling over a Bay Area city or suburb might land on a dizzying number of human-made surfaces: artificial turf, roofs, cars, pavement, windows, solar panels, construction sites, and many others. By the time water heads toward San Francisco Bay as stormwater runoff, it can collect hundreds of chemicals from these painted, treated, or worn-down surfaces. In all Bay Area cities except portions of San Francisco, stormwater flows straight to the Bay.  “The fundamental challenge of stormwater is that the scale is just really big,” says Karen Cowan, the executive director of the nonprofit California Stormwater Quality Association. “It’s the world we live in, for all practical purposes.” … ”  Read more from the San Francisco Estuary Institute.

State Water Board receives climate report, agrees action for Mono Lake is needed

“[Last] week the California State Water Resources Control Board focused on Mono Lake’s low level in a five-hour discussion at their regular meeting in Sacramento. A new Mono Lake report and hydrology model from the UCLA Center for Climate Science was the impetus for the agenda item, and there was robust discussion, followed by extensive public comments. At the conclusion, Board members agreed: a formal, decision-making hearing about Los Angeles Department of Water & Power (DWP) water diversions is necessary, this year.  The UCLA team presented a project overview and key findings. The report shows that while climate change is a factor, ongoing DWP water diversions are the main cause of the present-day low lake level. The report also shows that current diversion levels are unlikely to allow the lake to rise. However, Mono Lake recovery is still achievable if water diversions are reduced—a clear opportunity for meaningful action by the Board. … ”  Read more from the Mono Lake Committee.

A short-term pitch from Nevada has been the new starting point for the upper and lower basin states.  “Right now, we’re in discussions with the lower basin about a potential short-term agreement,” Lopez told New Mexico’s Interstate Stream Commission in a March 19 meeting.  Nevada proposes increasing water releases from upper basin reservoirs like Flaming Gorge by at least 500,000 acre feet to help prevent Lake Powell from dropping too low.  The latest forecasts predict Powell could drop enough to stop producing hydropower by December. … ”  Read more from KUER.

ASU hosts national water policy event, experts stress urgency of water in the Southwest

“Transforming Water, West gathered scholars, innovators and policymakers on March 20 to discuss solutions to counter the United States’ water challenges.  Previously known as the Rethinking Water series, the organizers rebranded the event to showcase a transition from thinking about water solutions to taking action to implement them. Urgency was stressed throughout the conference, with scientists sharing concerns about how current population growth contradicts the availability of water in the Southwest.  “We are in the midst of an area which is experiencing fairly critical water conditions,” said Upmanu Lall, the director of the Water Institute at ASU. “They are acknowledged to a certain extent, but what is going to be done about those is not really being talked about nearly as much.” … ”  Read more from Arizona State University.

Arizona hires high-powered law firm, setting the stage for a legal battle over Colorado River water

“Arizona is preparing for a legal battle over its rights to Colorado River water.  Following an extraordinarily dry winter along the river basin and what’s expected to be an exceptionally hot and dry spring across the West, where high temperatures in March have already blown past records, the pressure to maintain access to the state’s fair share of river water is growing.  The Colorado River is a vital source of drinking water for 40 million people in the seven basin states, Mexico and 30 Native American tribes, and provides water for farming operations and hydroelectricity.  Reaching a water usage agreement is imperative to the basin states as the river’s water supply continues to decline, as it has done for the past 25 years due to a persistent drought spurred on by climate change. … ”  Read more from the Arizona Mirror.

New water rules could put the squeeze on southern Arizona vineyards

“Arizona’s wine industry has seen exponential growth in the past three decades, going from a couple of wine producers in the early 1990s to about 168 today. Now, winemakers, viticulturists and their allies fear that new groundwater rules in southeastern Arizona could stunt that growth.  To make wine, you need wine grapes, and nearly 80% of all the fruit used by Arizona winemakers is grown in the Willcox groundwater basin. … ”  Read more from Arizona Central.

Cocopah Tribe launches habitat restoration project along Colorado River

“The Cocopah Indian Tribe’s Environmental Protection Office successfully completed its first ecological restoration project, restoring 40 acres at the Cocopah North Reservation.  Part of the project included a three-day workshop led by Fred Phillips of Fred Phillips Consulting. The workshop brought together more than 30 participants and volunteers, who contributed to hands-on fieldwork while learning planting and restoration techniques.  Phillips has specialized in large-scale restoration and ecological landscaping projects for over two decades. During that time, he has worked on numerous initiatives, including tribal projects in the Yuma wetlands along the Colorado River. When the Cocopah Tribe selected him for this project, he worked closely with the tribe to design a plan aimed at improving both habitat conditions and the quality of water flowing into the Colorado River. … ”  Read more from KAWC.

Colorado lawmakers step in — again — to urge federal action on stalled tribal water access

“The Southern Ute and Ute Mountain Ute Indian tribes have been pushing for the federal government to uphold its water-related responsibilities for years. Now, Colorado legislators are jumping back into the fight.  Lawmakers in the Colorado House of Representatives unanimously passed a resolution advocating for tribal water access Friday, during Ute Day at the Capitol. The resolution — which lists a series of longheld tribal water priorities and urges federal agencies to respond — awaits consideration in the Senate.  It calls on the feds to take action on everything from releasing frozen funding for tribal water projects to repair deteriorating federal water systems and improving access to reservoirs like Lake Nighthorse near Durango. … ”  Read more from the Colorado Sun.

Colorado lawmakers move to protect beavers as a way to mitigate the threat of wildfires

“A lack of snow and unseasonably warm temperatures in Colorado have significantly increased the risk of wildfires this year, and some state lawmakers are taking an unusual approach to help lower that risk.  HB26-1323 would outlaw the killing of beavers on public lands in Colorado, except in cases where beavers threaten infrastructure or public safety.  Supporters say not only do the dams built by beavers help regulate the state’s water supply, but the wetlands created by them also act as natural firebreaks, provide refuge for other wildlife during fires, and reduce downstream pollution after fires. … ”  Read more from CBS Colorado.

Blue states rip EPA’s ‘compliance first’ approach to enforcement

“Democratic state attorneys general called on the Environmental Protection Agency to retract a memo instructing regulators to advise industries on how to comply with environmental laws before issuing penalties.  The 13 attorneys general claim the memo puts the interests of businesses over the environment and public health. Without strong enforcement, industries have little incentive to comply with laws, the attorneys general allege.  “This administration’s approach gives polluters a tacit green light to break federal environmental laws,” Washington Attorney General Nick Brown said in a statement. … ”  Read more from the Capital Press.

Global review finds freshwater fish in peril

“Many freshwater fish worldwide are in crisis, according to a new global assessment, but varied solutions based on specific environmental needs may curb further population decline.  On Tuesday, researchers with the Convention on the Conservation of Migratory Species of Wild Animals (CMS) — an environmental treaty of the United Nations — formally introduced the first comprehensive report specifically designed to identify all transboundary migratory freshwater fish of conservation concern. The assessment evaluates the conditions and health of over 15,000 species.  The release of the assessment coincides with the CMS Conference of the Parties (COP15) taking place March 23 through March 29 in Campo Grande, Brazil.  Three hundred and twenty-five species of migratory freshwater fish are singled out in the assessment and need international protection, the researchers say. … ”  Read more from the Courthouse News Service.
