The tool is accessible to the public at url: https://orsanco-hab.shinyapps.io/shiny-ohio-river/#.  This presentation will overview the science of large river HABs and the historical data that was used to develop a risk characterization framework and then a probabilistic prediction of HABs for 20 locations spanning the entire length of the Ohio River. Next, a general overview of the web-based application will be given, including details about data acquisition, data management, and the underlying statistical models. Finally, perspectives on using the tool to actively monitor the river’s water quality and make decisions about HAB sampling and risk communication will be given by the tool’s primary user.  Click here to register.
  • GRA SoCAL (Hyrbrid): How to Get the Most of Your Transducer Data from 6:30pm to 9:00pm.  Consultants and agencies dealing with water resources issues across the United States install transducers in monitoring wells to collect millions of groundwater level measurements daily. Typically, the analytical focus is on water level fluctuation over time. Such a focus deals only with long-term trends or, at best, a signature of a nearby pumping well. The information that can be extracted from the time domain is only a small part of a much larger picture; this is due to the limitations of tools that analyze data in the time domain. By switching to the frequency domain and using signal processing tools, it is possible to extract a full range of valuable information that can lead to a better understanding of the functioning of aquifers.

Water rules add to challenges for farmers

Already grappling with drought, lower commodity prices and higher production costs, more farmers are feeling the added pinch of groundwater regulations as local agencies implement plans that include pumping limits and new fees to balance long-term groundwater resources as required by the state.  Looking over his toppled almond orchard, Madera County farmer Jay Mahil of Creekside Farming Company Inc. says he must fallow 500 acres of almonds and winegrapes due to water shortages. Mahil and other farmers who face lower prices and higher costs are also subject to new, per-acre fees to help local agencies fund groundwater management. … ”  Read more from Ag Alert here: Water rules add to challenges for farmers

Back Forty: Hard truths about California’s water future

Teresa Cotsirilos writes, “Last month, Jay Lund, a distinguished professor of civil and environmental engineering at UC Davis, wrapped up a lecture on California’s drought with a slide titled, “Resistance is Futile.” It included a list of his predictions about the state’s water crisis, some of which bordered on apocalyptic. As climate change fuels extreme drought, heat and flooding, Lund explained, some of California’s native species will become unsustainable in the wild. Farmers, government agencies and environmental groups will continue to fight over dwindling water supplies. In the San Joaquin Valley, farmers could be forced to fallow 40 percent of their land. “These things will happen,” says Lund, who has been studying California’s water situation for over 30 years. “I don’t see anybody being willing to spend enough money to completely reverse these trends.”   I spoke with Lund recently about his predictions. Our conversation focused on the San Joaquin Valley, which is one of the most productive agricultural regions in the world. … ”  Read more from the Food & Environment Network here: Back Forty: Hard truths about California’s water future

These are the driest reservoirs in California

Despite recent rain storms across the state, California’s historic drought shows no signs of slowing down any time soon.  With the lack of meaningful regular precipitation, capacity at California’s reservoirs continue to decline, putting stress on the state’s water supply.  Across the board, nearly all of California’s major water supply reservoirs managed by the California Department of Water Resources are well below historic averages.  The state’s largest water reservoirs, Lake Oroville in Butte County and Shasta Lake in Shasta County, currently sit just shy of half of historical averages. … ”  Read more from KTLA here: These are the driest reservoirs in California

Dan Walters: Another step toward agreement on California’s water

For at least a decade, off and on, state water managers and local water agencies have pursued the holy grail of a master agreement to improve the environmental health of the Sacramento-San Joaquin Delta by increasing its water flows.  At any given moment, California’s water supply is a zero sum game. Therefore, increasing flows through the Delta to improve habitat for salmon and other species would require local water agencies, particularly those serving farmers, to take less from the Sacramento and San Joaquin rivers and their tributaries.  That’s not only a hard sell, but also could interfere with water rights, some of which stretch back to the 19th century. State officials have hoped that so-called “voluntary agreements” would forestall direct action that could touch off a legal donnybrook over those rights. … ”  Read more from Cal Matters here: Dan Walters: Another step toward agreement on California’s water

Districts agree to collaborate on Tuolumne River

Modesto Irrigation District, Turlock Irrigation District and the San Francisco Public Utilities Commission have signed a memorandum of understanding with the state to advance a voluntary agreement for the Tuolumne River.  MID and TID, which jointly operate the Don Pedro Reservoir on the Tuolumne River, joined dozens of other California water agencies in committing to collaborate with the state to finalize agreements that will provide water supply reliability to communities, while enhancing river ecosystems. Contra Costa Water District signed onto the agreement in September.  Details from the agreement signed last week are expected to be scrutinized more closely as the process unfolds. … ”  Read more from Ag Alert here: Districts agree to collaborate on Tuolumne River

“Change” candidates sweep Westlands Water District board election; may dump longtime General Manager Tom Birmingham

The math was not in Tom Birmingham’s favor.  It was clear weeks before the Nov. 8 election that the board of the massive Westlands Water District in western Fresno County would be changing. And that change would likely result in the controversial General Manager’s ouster.  There were four board seats up for election.  A preliminary vote count released by the district Monday night confirmed a sweep of all four seats by the so-called “change coalition.” With two existing board members already counted among the change coalition, that gives it a solid majority of six on the nine-member board.  And No. 1 on the coalition’s to-do list is “A change in leadership,” according Sarah Woolf, who along with Jon Reiter helped coordinate a group of increasingly frustrated Westlands farmers to run the slate of change candidates. … ”  Read more from SJV Water here:  “Change” candidates sweep Westlands Water District board election; may dump longtime General Manager Tom Birmingham

Anglers, scientists consider potential changes in sturgeon regulations

Fishing for white sturgeon has been relatively productive on the West Delta and Suisun Bay over the past two weeks, but some anglers and prominent scientists are supporting changes in fishing regulations to preserve the prehistoric fish for the future.  Hundreds of white sturgeon and some green sturgeon perished in San Francisco and San Pablo bays in late August in a massive fish kill spurred by a red tide algae bloom, but the exact number of fish killed is unknown.  Captain Zack Medinas of Gatecrasher Fishing Adventures reported “very good” sturgeon fishing on his latest few trips, but ponders how long this fishery will last at current rates of harvest. … ”  Read more from the Stockton Record here: Anglers, scientists consider potential changes in sturgeon regulations

Conservationists, fishermen, and tribes sue over fish farming slated for federal waters

Center for Food Safety (CFS), on behalf of itself and nine conservation, tribal, and fishing organizations, filed a federal lawsuit in U.S. District Court, Western District of Washington yesterday challenging the U.S. Army Corps of Engineers’ nationwide permit 56, which authorizes industrial finfish aquaculture structures in state and federal ocean waters around the country.   The Army Corps approved the nationwide permit despite scientific studies and industry in other countries demonstrating that commercial finfish aquaculture poses significant threats to marine ecosystems and endangered whales, salmon, sea turtles, and many other imperiled species, as well as to traditional fishing economies, Tribal Nations’ food security, and public health.  Nationwide permit 56 originated from a Trump-era executive order promoting rapid expansion of industrial marine aquaculture facilities under the guise of addressing pandemic-related food insecurity. The permit will allow the 16 adopting Army Corps districts—in Alaska, California, Oregon, Washington, Florida, Texas, Georgia, North Carolina, New York, New Jersey, Philadelphia, Hawaii, and Virginia—to streamline permitting for this new, ecologically destructive aquaculture industry. … ”  Read more from the Center for Food Safety here: Conservationists, fishermen, and tribes sue over fish farming slated for federal waters

Can seismic instruments act as early warning systems for flooding?

Predicting floods often depends on measuring water height with stream gauges. But for sudden and profound flooding events, gauging stations can be drowned early on, leaving nearby residents and city managers in the dark.  In a new paper, “A Seismic Approach to Flood Detection and Characterization in Upland Catchments,” published last month in Geophysical Research Letters, researchers looked at an alternative to stream measurements during floods. They turned to a seismic monitoring instrument, or seismometer, to reconstruct the signatures of the flood — not just the height of the water but the velocity, amount of sediment and debris the water was carrying, and the path of the flood through the valley. … ”  Read the full article at Civil Engineering Source here: Can seismic instruments act as early warning systems for flooding?

UC expert helps save water, increase supply

Earlier this year, officials in Southern California declared a water shortage emergency resulting in restrictions such as limiting outdoor water use to one day of the week.  While mandatory restrictions vary across the region, Amir Haghverdi, University of California Cooperative Extension specialist and associate professor of agricultural and urban water management at UC Riverside, is using research to pinpoint irrigation strategies that will help communities reduce their demand for water and increase supply.  Haghverdi and his team are responding to a hotter and drier California by working to identify changes that can make a substantial difference in water savings. … ”  Read more from the Western Farm Press here: UC expert helps save water, increase supply

Smarter ways with water:  People need to find better and more productive ways to become allies with water — which might mean giving it space for its processes

In just a few months this year, abnormally low water levels in rivers led China to shut down factories and to floods in one-third of Pakistan, killing around 1,500 people and grinding the country to a halt. A dried-up Rhine River threatened to tip Germany’s economy into recession, because cargo ships could not carry standard loads. And the Las Vegas strip turned into a river and flooded casinos, chasing customers away. It seems that such water disasters pepper the news daily now.  Many businesses have long lobbied against changing their practices to safeguard the environment, by refusing to implement pollution controls, take climate action or reduce resource use. The costs are too high and would harm economic growth, they argue. Now we are seeing the price of that inaction. … ”  Read more from Nature here:  Smarter ways with water

Farm groups highlight the importance of alfalfa in the face of ongoing western drought

With drought conditions continuing to blanket the Western U.S., and farmers struggling to find adequate water supplies, competing interests are pressuring the federal government to cut the water supply farmers are using to grow our food, including alfalfa, which is a foundational food chain crop.  In response, the Family Farm Alliance and California Farm Water Coalition have produced a White Paper titled, “Our Food Supply at Risk; The Importance of Alfalfa Production in the American West,” detailing the valuable role alfalfa plays as a principal feed source for the nation’s livestock and diary industries, its environmental benefits, and contribution to effective drought management.  Family Farm Alliance Executive Director, Dan Keppen, said reducing the acreage devoted to alfalfa may seem like an easy fix to save water, but a decision to do so has bigger ramifications for our nation’s food supply. … ”  Read more from the California Farm Water Coalition here: Farm groups highlight the importance of alfalfa in the face of ongoing western drought

The changing face of agriculture

Food, fiber and fuel make up the trifecta of agriculture. As we approach Thanksgiving and reflect on what we’re grateful for, those provisions often spring to mind—especially in time for cooking up holiday feasts and keeping warm in the cooler months. But rising threats like climate change, political instability, growing populations and increasing prices are upending the security of those agricultural products across the world.  Researchers at the CSU are seeking ways to make agricultural practices more sustainable and climate-resilient to ensure the industry will meet future global needs. To support these endeavors, the California 2022-23 state budget awarded the CSU one-time funding of $75 million, split evenly between Chico State, Fresno State, Cal Poly Pomona and Cal Poly San Luis Obispo.  See how these four universities are enhancing their agriculture programs, preparing the next generation of experts and securing the industry’s future success. … ” Read more from California State University here: The changing face of agriculture 

Western U.S. streamflow declines respond asymmetrically to seasonal climate warming

Although numerous studies have previously explored streamflow responses to annual climate warming, less attention has been given to the differing effects of seasonal (winter vs. summer) warming. It is well-known, for instance, that the seasonal timing of streamflow in snow-affected river basins is strongly affected by warmer winters, which lead to less snow, more rain, and earlier runoff. What has been less understood is how the total volume of runoff changes in a warmer climate, and in particular how the total (annual) streamflow volume responds to warmer winters as contrasted with warmer summers.  To address this gap, UCLA’s Land Surface Hydrology Group examined western U.S. streamflow declines in response to climate warming and found they are expected to be asymmetric depending on the season in which most warming occurs. … ”  Read more from Cal Ag Today here: Western U.S. streamflow declines respond asymmetrically to seasonal climate warming

Megadroughts in the common era and the Anthropocene

In recent years, severe droughts have affected many regions around the world, including western North America, Europe, East Africa, and China. In some cases, these events (and others) have been referred to as “megadroughts,” a term increasingly used in the media and scientific literature to refer to almost any extreme or impactful drought event. There is little consensus in the scientific community, however, on when a drought becomes a megadrought, nor is there any quantitative or established definition. A recently published paper by a team of international scientists synthesized information from the paleoclimate record, observations, and climate models to summarize our current understanding of megadrought dynamics around the world, from the last two thousand years to the end of the current century (Cook et al., 2022). What is a megadrought? Where in the world do they occur? And what are the consequences of climate change for megadrought risk and severity? … ”  Read more from NIDIS here: Megadroughts in the common era and the Anthropocene

Ski season 2022: California mountain resorts roll out the white carpet

It’s that time again! The first winter storm of the season on Nov. 1 and a big dump the next week created anticipatory excitement at California’s mountain resorts. Mammoth Mountain started turning lifts on Nov. 5, while many other resorts opened last weekend, two-plus weeks ahead of schedule. It’s an auspicious start for an industry that usually doesn’t start cranking up until late November to mid-December.  Pandemic-era restrictions in place for the last three seasons have been relaxed. No more “Mask up! Over the nose!” exhortations on the slopes, but keep that mask in your pocket nevertheless, as some resorts will require it indoors.  But some pandemic-era innovations remain in place. RFID technology, which uses a chip inside your pass card to automatically open a gate, will get you on board the lifts.

In its suit, the Navajo Nation argues that the Department of Interior has a responsibility, grounded in treaty law, to protect future access to water from the Colorado River. Several states and water districts have filed petitions opposing the tribe, stating that the river is “already fully allocated.”  The case highlights a growing tension in the region: As water levels fall and states face cuts amid a two-decade-long megadrought, tribes are working to ensure their water rights are fully recognized and accessible. … ”  Read more from Grist here: Tribes in the Colorado River Basin are fighting for their water.

Arizona’s water supply is shrinking, but its population is growing. Is it sustainable?

Meredith Deangelis moved to the community of Rio Verde Foothills, north of Scottsdale, 11 years ago.   The family settled on a four-acre property with a view of Four Peaks where their young daughter and three dogs loved to play. They started raising chickens.  It seemed like an ideal desert home, except for one thing.  “When I purchased my home, actually, I should have asked more questions,” Deangelis said.  Like hundreds of others in the area, the home relies on hauled water — a big truck periodically delivers water from Scottsdale to fill a tank on the property.  Deangelis knew that. She didn’t know that the city of Scottsdale might one day cut off that supply.  Scottsdale is more reliant on Colorado River water than most other Valley cities. And since Arizona’s Colorado River supply is now facing drastic cuts, Scottsdale is putting an end to non-resident water sales next year.

Groundwater is critical to rural Arizona — but there’s a struggle to regulate it

Every now and then it rains in the Arizona desert.  Some of that water finds its way into cracks and crevices and then pools underground. Over thousands of years, that water has filled basins, and if you drill deep enough, you might find it. Most of rural Arizona survives on groundwater, and most of it is unregulated.  Haley Paul of the Audubon Society says that lack of oversight is beginning to show, because as water tables drop, big companies are drilling deep wells.  “Every year, the water table is dropping,” Paul said. “And every year more people’s wells are going dry. And we’re just letting it happen.”  Big agriculture has discovered Arizona’s soil, sunshine and laissez faire mindset. … ”  Read more from KJZZ here: Groundwater is critical to rural Arizona — but there’s a struggle to regulate it

Airports and other places that rely on PFAS-enabled foams to fight fires should start to prepare to manage the wastes they’ll generate by switching to non-PFAS alternatives, attorneys and consultants say.  Congress ordered the Pentagon to release requirements for firefighting foams made without per- and polyfluoroalkyl substances (PFAS) by the end of January.  Once new PFAS-free foams that meet the military’s standards are available, that will open the door to military facilities along with oil refineries, airports, fire departments, and other private entities replacing their existing stocks of the PFAS-based foam, or AFFF (aqueous film-forming foam).  But swapping the PFAS-based fire suppressants at just one facility can generate tens of thousands of gallons of waste, said Matthew Magnuson, a chemist with the Environmental Protection Agency’s research office. … ”  Read more from Bloomberg Law here: Fear of PFAS disposal costs looms over firefighting foam switch

5 things to know about how SWOT will look at the world’s water

On Dec. 12, NASA will launch the Surface Water and Ocean Topography (SWOT) satellite into Earth orbit from Vandenberg Space Force Base in California atop a Falcon 9 rocket. The mission is a collaborative effort between NASA and the French space agency Centre National d’Études Spatiales (CNES) – with contributions from the Canadian Space Agency (CSA) and the UK Space Agency – that will survey water on more than 90% of the planet’s surface.  The satellite will measure the height of water in Earth’s freshwater bodies and the ocean, providing insights into how the ocean influences climate change; how a warming world affects lakes, rivers, and reservoirs; and how communities can better prepare for disasters, like floods.  Here are five ways that SWOT will change what we know about water on Earth ... ”  Read more from JPL here: 5 things to know about how SWOT will look at the world’s water 

NASA study: rising sea level could exceed estimates for U.S. Coasts

By 2050, sea level along contiguous U.S. coastlines could rise as much as 12 inches (30 centimeters) above today’s waterline, according to researchers who analyzed nearly three decades of satellite observations. The results from the NASA Sea Level Change Team could help refine near-term projections for coastal communities that are bracing for increases in both catastrophic and nuisance flooding in coming years.  Global sea level has been rising for decades in response to a warming climate, and multiple lines of evidence indicate the rise is accelerating. The new findings support the higher-range scenarios outlined in an interagency report released in February 2022. … ”  Read more from NASA here: NASA study: rising sea level could exceed estimates for U.S. Coasts
