DWR DISTANCE LEARNING: Navigating the Maze: Salmon in the Delta from 1pm to 1:30pm

Join DWR Senior Scientist, Dr. Brett Harvey, for a live presentation and chat as he describes the journey taken by juvenile salmon through the Sacramento-San Joaquin Delta.  Before the salmon born in California’s Central Valley can get to the ocean, they must first make it through the San Francisco Upper Estuary, a maze of channels and sloughs that includes the Delta. Along the way, they need good habitat – places where they can find food without becoming food themselves. Only a small percentage of juvenile salmon survive this part of the journey.  Dr. Harvey will describe this journey, and some of the things we are doing to help more juvenile salmon make it from their birth rivers to the ocean.  Watch on DWR’s YouTube Channel or register and join through Zoom to ask Dr. Harvey questions.

Past wildfires offer future roadmap for forest management’s effects on water

Forest restoration is often associated with mitigating wildfire risk and improving ecosystem health throughout the Sierra Nevada. But restoration also dramatically affects water use within forests and the amount of runoff that flows downstream.  The Sierra Nevada provides more than 60 percent of California’s water supply and sustains a globally important agricultural region. Quantifying the water-related benefits can be critical in showing the true value and cost-benefit of forest management. But until now, there hasn’t been enough locally relevant data to incentivize restoration projects.  New research from UC Merced’s Sierra Nevada Research Institute (SNRI) fills this data gap and provides a method to monetize the water-related benefits of forest thinning. … ”  Read more from UC Merced here:  Past wildfires offer future roadmap for forest management’s effects on water

The consequences of spraying fire retardants on wildfires

Wildfires started burning in California early again this dry season—more than two million acres have burned so far. Larger and larger wildfires are occurring as new heat records are being broken each year.  Firefighting efforts have leaned heavily on aerial spraying of fire retardants, but their environmental and health effects are little studied, says Jordyn Ellorin, VG19, a native Californian who received an M.S. in conservation medicine (MCM) from Cummings School of Veterinary Medicine. … ”  Read more from Phys Org here:  The consequences of spraying fire retardants on wildfires

Creek Fire ignites fire management debate on 102 million trees killed by beetles, drought

When the Creek Fire exploded to 160,000 acres in just 72 hours, ripping through a jewel of the Sierra Nevada just south of Yosemite National Park, California and the world looked on in horror and surprise.  But the stage had long been set for the megablaze, one of a half-dozen transforming millions of acres of Golden State landscapes to ash. Droughts supercharged by climate change dried out vegetation, aiding its transition into fuel. And as observers ranging from foresters to Californians living in the wildland urban interface predicted, the state’s zealous, century-long fight to suppress fires meant this flammable concoction grew to unstable levels. … ”  Read more from the USA Today here: Creek Fire ignites fire management debate on 102 million trees killed by beetles, drought

Analysis: Trump blames California for fires. He should check to see whose land they’re on.

With wildfires raging and smoke choking the West Coast’s cities and towns, President Donald Trump has repeatedly blamed state officials in California, Oregon and Washington for the conflagrations, suggesting they have done a poor job of managing their forests—even suggesting that they somehow rake the forests to prevent fire.  But when Trump met California officials this week for a briefing on the wildfires, CalFire director Thomas Porter showed him a map of California’s fires, most of which were located on territory the map colored green. … ”  Read more from Politco here: Analysis: Trump blames California for fires.

In a dry state, farmers use oil wastewater to irrigate their fields, but is it safe?

For decades, farmers in California’s Kern County have turned to wastewater from oil production to help irrigate their crops during extended dry spells.  The wastewater provides an alternative to groundwater, which has become increasingly scarce as farmers have pumped more than they could replenish.  But the use of the recycled water, a byproduct of oil and natural gas extraction that is mixed with surface water for irrigation, has stirred controversy. … ”  Read more from Inside Climate News here: In a dry state, farmers use oil wastewater to irrigate their fields, but is it safe?

Transforming water management in the U.S. West with NASA data

Building upon more than two decades of research, a new web-based platform called OpenET will soon be putting NASA data in the hands of farmers, water managers and conservation groups to accelerate improvements and innovations in water management. OpenET uses publicly available data and open source models to provide satellite-based information on evapotranspiration (the “ET” in OpenET) in areas as small as a quarter of an acre and at daily, monthly and yearly intervals.  Evapotranspiration is the process by which water is transferred from the land to the atmosphere, by water leaving the soil (evaporation) and water lost through plant leaves and stems (transpiration). Evapotranspiration is an important measure of how much water is used or “consumed” by agricultural crops and other plants. … ”

Click here to continue reading this press release.

In the arid western United States, where the majority of water used by people is for irrigation to grow crops, having an accurate measure of evapotranspiration is critical to balancing water supplies and water demand. Until OpenET, there has not been an operational system for measuring and distributing evapotranspiration data at the scale of individual fields across the western United States. OpenET will be available to the public next year, supplying evapotranspiration data across 17 western states.

“What OpenET offers is a way for people to better understand their water usage and, more importantly, their water loss through evapotranspiration,” said Denise Moyle, an alfalfa farmer in Diamond Valley, Nevada, and an OpenET collaborator. “Giving farmers and other water managers better information is the greatest value of OpenET.”

The OpenET platform is being developed through a unique collaboration of scientists, farmers and water managers from across the western United States, as well as software engineers specializing in data access and visualization for large Earth observation datasets.

Led by NASA, the nonprofit Environmental Defense Fund (EDF), the Desert Research Institute (DRI) and data applications developer HabitatSeven, with funding from the Water Funder Initiative and in-kind support from Google Earth Engine, OpenET primarily uses satellite datasets from the Landsat program, which is a partnership between NASA and the U.S. Geological Survey (USGS). Additional data comes from NASA’s Terra and Aqua satellites, the National Oceanic and Atmospheric Administration (NOAA) GOES series of satellites and others.

“OpenET will empower farmers and water managers across the West to build more accurate water budgets and identify stress, resulting in a more resilient system for agriculture, people and ecosystems,” said Maurice Hall, head of EDF’s Western Water program. “We envision OpenET leveling the playing field by providing the same trusted data to all types of users, from the small farmer to regional water planners.”

California’s Delta Watermaster Michael George is responsible for administering water rights within the Sacramento-San Joaquin River Delta, which supplies drinking water to more than 25 million Californians and helps irrigate 3 million acres of farmland. For him, the development of OpenET signals an exciting opportunity for the future of water in the West.

“OpenET represents a game-changing leap forward for water management,” George said. “It will help landowners and water managers in the Bay-Delta save millions of dollars that would otherwise have to be spent on water meters to more accurately measure water use, as required by state law.”

In addition to helping Delta farmers save costs, OpenET data will improve water management in the area, according to Forrest Melton, program scientist for NASA’s Western Water Applications Office. He is also with the NASA Ames Research Center Cooperative for Research in Earth Science and Technology (ARC-CREST).

“The importance of careful, data-driven water management in the Delta and other regions can’t be overstated,” he explained. “In addition to supplying water for drinking and growing food, the Delta provides critical habitat for endangered species. For a water manager, trying to balance all of these demands is almost impossible without accurate, timely data.”

The OpenET team is currently collaborating with water users on several case studies across the West. In California’s Central Valley, the Rosedale-Rio Bravo Water Storage District is already starting to use OpenET data as the foundation for an online water accounting and trading platform to help farmers in the district manage groundwater sustainably. In Colorado, high-altitude ranchers will be using OpenET as they experiment with different irrigation strategies to conserve water.

Landsat science team member Justin Huntington of DRI emphasized the value of getting this type of early feedback on the OpenET system from future users. “Working closely with farmers and water managers on the design of OpenET has given us invaluable insights into how to best make ET data available to support water management in Diamond Valley and other basins across the West,” he said.

Because the OpenET system uses open source software and open data sources, it will help water managers establish an agreed upon measure of evapotranspiration across agricultural areas, said Melton. Different estimates of evapotranspiration have previously been a source of confusion for water managers, he said, explaining that water users and managers currently have to evaluate a variety of methodologies to measure water use and evapotranspiration, which often leads to different numbers and debates over accuracy.

OpenET provides a solution to those debates, said project manager Robyn Grimm. “OpenET brings together several well-established methods for calculating evapotranspiration from satellite data onto a single platform so that everyone who makes decisions about water can work from the same playbook, using the same consistent, trusted data,” said Grimm, who is also a senior manager at EDF.

The need for a resource like OpenET is also pressing beyond California and across the American West, Melton said.

“Our water supplies in the West are crucial to providing food for the country and beyond, and yet these supplies are under increasing levels of stress,” Melton said. “OpenET will provide the data we need to address the challenge of water scarcity facing many agricultural regions around the world and ensure we have enough water for generations to come.”

Evaporation adds up. How much? Google it – someday

There are lots of new water gizmos popping up these days but there’s only one Google.  Which makes the massive tech company’s involvement in a proposed water measurement tool both intriguing and slightly suspicious to some agricultural water managers.  The same goes for another partner in the effort, the Environmental Defense Fund, a well-known advocacy group that has been at odds with farming interests in past years. … ”  Read more from SJV Water here:  Evaporation adds up.

Metropolitan board cuts spending in response to pandemic, lower water sales

In response to lower water sales and concerns about the financial impacts of COVID-19 on its member agencies and the public, the board of directors of the Metropolitan Water District of Southern California today voted to approve a cost-cutting plan to reduce district expenditures. The cuts will save about $11.7 million, while allowing Metropolitan to continue providing the safe, reliable water supply Southern California depends on. Staff will continue exploring additionalopportunities for savings to bring back to the board for a mid-cycle budget review next summer. The full consequences of the pandemic’s financial impact on Metropolitan’s member agencies are not yet known, and declining revenue, low water sales, and an increased reliance on district reserves necessitate fiscal discipline, Metropolitan board Chairwoman Gloria Gray said. …

While most of our member agencies are successfully managing through these difficult times, there is a lot of uncertainty ahead. So it is critical that we take every step possible to cut spending without sacrificing the essential service we provide to the region,” Gray said. “COVID-19, wildfires and other challenges to our water supply due to climate change require us to maintain and adapt our water system to ensure Southern California’s people, businesses, hospitals and communities have the water they need through these difficult times.”

The board also directed staff to develop a penalty-free payment deferment program, evaluate potential new revenue-generating programs, and place a moratorium on non-emergency, unbudgeted spending. The latest cuts come on top of additional measures to reduce spending made in April, when the board approved the biennial budget.”

Santa Ana Water Board delays decision on Orange County desalination project

The Santa Ana Regional Water Quality Control Board, which was expected to make a decision September 17 on the waste discharge permit renewal  for a proposed seawater desalination facility in Orange County, has postponed action for several weeks at the request of the applicant.  Poseidon Waters, the company that plans to build the $1 billion plant on 12 acres of the AES Huntington Beach Generating Station, requested additional time to address concerns raised in three days of public hearings, among them: the need and cost of desalinated water; Orange County Water District’s commitment to purchase the supply; the harm to marine life caused by the facility’s intake process; and whether the Bolsa Chica wetlands Marine Life Mitigation Plan satisfies the state’s Ocean Plan requirements for seawater desalination plants. …

Reclamation projects Colorado River drought operations for the next 5 years

Modeling results for the Colorado River Basin operations released today by the Bureau of Reclamation indicate continued drought and an increased chance of potential water shortages by 2025. The Colorado River Basin is in its 21st year of an extended drought. As reservoir levels decline, Lake Powell and Lake Mead operations are potentially impacted. The Colorado River Simulation System modeling results, released at least three times per year, provide water managers with information needed to plan accordingly for the future. … ”

Click here to continue reading this press release.

“Reclamation’s technical experts provide leading-edge scientific modeling which helps Colorado River water managers make their operational decisions,” said Commissioner Brenda Burman. “That science helps us protect the water resources in the Basin, ensuring sustainable, reliable water and hydropower for the 40 million people who depend on this river.”

Due to the below average runoff this year (55% of average for the water year), the CRSS projections indicate an increase by as much as 12 percent in the chance of Lake Powell and Lake Mead falling to critically low reservoir levels by 2025 as compared with the projections released this spring. The chance of a Lower Basin shortage determination increased by as much as 20 percent through 2025, assuming a dry hydrologic future similar to what the Basin has experienced over the past 2 decades.

These increases put the chances of reaching critically lower levels near 20 percent and a Lower Basin shortage near 80 percent by 2025. The CRSS projections can be found at https://www.usbr.gov/lc/region/g4000/riverops/coriver-projections.html.

A key source of Reclamation’s technical capability comes through a partnership with University of Colorado-Boulder, where Reclamation helped establish and continues to support the Center for Advanced Decision Support for Water and Environmental Systems. In collaboration with the Colorado River regional operations offices, Reclamation uses the best available science to develop reliable projections to guide water management and operational decisions.

The extended drought increases the importance of ongoing drought contingency actions and operational adjustments that Reclamation and partner entities have taken on the river. These actions successfully demonstrate that voluntary, compensated water conservation projects can conserve water for the Colorado River system storage and help mitigate the impacts of drought.

Dams alter nutrient flows to coasts

The right balance of nutrients is crucial for a healthy coastal ecosystem. If rivers deposit too much nitrogen and phosphorus in coastal areas, algae that flourish on those nutrients can cause dead zones; if too little silicon flows downstream, organisms that depend on it will die off. Human interventions, whether through the addition of nutrients or through direct alteration of river flows, tend to upset natural nutrient balances. In a new study, Maavara et al. modeled how dams affect ratios of nitrogen, phosphorus, and silicon in coastal waters around the world. ... ”  Read more from EOS here: Dams alter nutrient flows to coasts
