Desalination: Should California use the ocean to quench its thirst?

As the state’s water supplies continue to dwindle during this drought, it’s always worth weighing the pros and cons of desalinization to meet the state’s water needs.  Groundwater keeps shrinking, reservoirs keep drying. Is it time for California to use desalinization to increase its depleted water supplies?  Here we are again: California is enduring another punishing drought, this one only a few years after the last one ended, which was the most severe drought in the state’s nearly 500 years of recorded history. Low winter snowpack combined with scorching summer temperatures and the driest winter months in 100 years have severely impacted the state’s water supply. … ”  Read more from Capitol Weekly here: Desalination: Should California use the ocean to quench its thirst?

PG&E plans to decommission Potter Valley Project

Pacific Gas & Electric does not believe it’s necessary to reexamine its license terms for endangered species at the Potter Valley Project as it prepares to decommission the dams, according to a letter the utility submitted to federal regulators.  PG&E submitted letters to the Federal Energy Regulatory Commission on Friday stating that it would take about 30 months to submit an application to surrender its license once its plan and schedule for doing so receives approval from the federal agency. On Tuesday, PG&E sent another letter stating that the letter sent by the National Marine Fisheries Service stating the terms for endangered fish species should be reevaluated in the interim contained “legal and factual inaccuracies” though it was willing to revisit some terms “so long as any revisions reflect the same level of effort and funding as is currently required.” … ”  Read more from the Eureka Times-Standard here: PG&E plans to decommission Potter Valley Project

Fish conservation groups criticize PG&E’s refusal to protect listed salmon and steelhead in the Eel River

On Monday, July 11th Pacific Gas & Electric Company (PG&E) proposed a schedule for filing a license surrender application and decommissioning plan for the Potter Valley Project. This filing with the Federal Energy Regulatory Commission (FERC) sets the stage for eventual removal of the Project.  … PG&E, in a separate filing on July 12th, responded to a March 17, 2022 letter from the National Marine Fisheries Service (NMFS) citing new evidence that the Project is harming endangered salmon more than previously believed, asking PG&E to re-initiate consultation under the Endangered Species Act (ESA), and to immediately adopt interim measures to limit the damage to fish in the meantime. In this filing, PG&E refuses to re-initiate consultation, claiming it is not necessary and that additional protective measures for fish are not required. … Read more from Cal Trout here: Fish conservation groups criticize PG&E’s refusal to protect listed salmon and steelhead in the Eel River

Partners return winter-run chinook salmon eggs to McCloud river: Drought action moves endangered salmon back into their historical habitat for first time since construction of Shasta Dam

The Winnemem Wintu Tribe, the California Department of Fish and Wildlife (CDFW), the National Oceanic and Atmospheric Administration (NOAA) Fisheries and the U.S. Fish and Wildlife Service (USFWS) on Monday celebrated the return of endangered winter-run Chinook salmon eggs to the McCloud River upstream of Shasta Reservoir for the first time since the construction of the Shasta Dam in the 1940s.  The partners collected approximately 20,000 fertilized winter-run Chinook salmon eggs from USFWS’ Livingston Stone National Fish Hatchery near Redding and drove them more than three hours over 80 miles to the Ah-Di-Na Campground within the Shasta-Trinity National Forest on the banks of the McCloud River. The eggs were placed into specialized incubators alongside the McCloud River’s cold waters where the species once spawned. Another 20,000 eggs will be transferred to the incubators in the McCloud River in early August. Both cohorts will be released into the river as fry. ... ”  Read more from the Department of Fish & Wildlife here: Partners return winter-run chinook salmon eggs to McCloud river: Drought action moves endangered salmon back into their historical habitat for first time since construction of Shasta Dam

Mapping a state’s secret water:  How groundwater mapping could be a game-changer for California

In California, hidden under the ground are aquifers that have the capacity to store an estimated 1.3 billion acre-feet of water—26 times all of the state’s reservoirs combined. All California needs to do is guide the floods caused by torrential rainfall into the ground, instead of out to sea. “If we just capture the upper 5 to 10 percent of flood flows, that is enough water to compensate for the loss of water due to climate change,” says Fogg.  Here’s the problem: We don’t know where to build this infrastructure. Because we can’t see groundwater, our understanding of it—where it is, which direction it flows, and how it connects to the surface—is limited. “It’s been out of sight, out of mind,” says Fogg.  That’s beginning to change. In 2021, California’s Department of Water Resources began an ambitious collaboration with a team of scientists to map the state’s complex groundwater network. The project will provide the data that local municipalities can use to begin harnessing the floods when they come. … ”  Read more from the Sierra Club here: Mapping a state’s secret water:  How groundwater mapping could be a game-changer for California

California’s 2021-22 snowpack – prelude to a drought

The Sierra Nevada Conservancy’s service area provides water to more than 75 percent of Californians and vast swathes of Central Valley farmland. Much of this water supply falls as snow across the high-elevation landscapes of California’s Sierra Nevada and Cascade mountains where it is stored as snowpack through the winter and spring. As the heat of summer arrives, snowmelt makes its way into reservoirs where it can be allocated throughout the state during the dry season.  The majority of California’s engineered water system relies on the upper watersheds’ natural infrastructure that captures and stores precipitation. Managing these landscapes to maximize spring snowpack accumulation complements water conservation efforts and will be increasingly important as our climate continues to warm. … ”  Read more from the Sierra Nevada Conservancy here: California’s 2021-22 snowpack – prelude to a drought

Californians struggle to cut water use

Californians are saving more water, but it’s still not enough to meet Governor Newsom’s goal of reducing water use by 15 percent, reports Hayley Smith in the Los Angeles Times. “After months of middling efforts — including a 17.6% increase in urban water use in April — residents in May saved 3.1% more water than in the same month in 2020, the baseline year against which current data are measured, according to new figures from the State Water Resources Control Board.” … ”  Read more from Planetizen here: Californians struggle to cut water use

Column: My broken sprinkler sent me on a quest. Can dowsers help us through the drought?

Columnist Steve Lopez writes, “So how did I end up with a city employee traipsing across my front yard with divining rods on a recent evening, searching for underground water?  The answer begins with a boneheaded blunder on my part. I accidentally clipped a sprinkler head on the edge of the driveway while pulling into my yard, and water began bubbling up from underground.  I’d never used those sprinklers and thought the line was dead when I bought the house five years ago. Clearly it was not, and water was now running down the street in the middle of a drought. So I called the emergency number for the Pasadena Water Department, and the operator promised to send a troubleshooter. … ”  Continue reading from the LA Times here: Column: My broken sprinkler sent me on a quest.

Atmospheric rivers help coastal wetlands build up sediment

Extreme precipitation from hurricanes and atmospheric rivers can lead to increased flooding in the world’s coastal zones, where more than 630 million people reside. Tidal marshes act as important buffers in these areas, absorbing the initial impact of storm surges and strong winds. In addition, tidal marsh ecosystems rely on storm events to deposit sediments that help with marsh accretion.  In a new study, Thorne et al. focused on tidal marsh accretion and elevation change in the San Francisco Bay after an atmospheric river event in 2016-2017. The authors installed deep rod surface elevation table instruments and feldspar marker horizon plots at five marsh sites differing in salinity and tidal range to determine vertical accretion and elevation changes. … ”  Read more from EOS here: Atmospheric rivers help coastal wetlands build up sediment

For western wildfires, the immediate past is prologue

Since 1984, satellites have observed a growing trend in summer wildfire activity in the western United States, with the total burned area increasing by 104,000 acres (42,100 hectares) per year on average [Abolafia-Rosenzweig et al., 2022]. From 1984 to 2000, wildfires across an area including all or parts of 11 states burned about 27.4 million acres in total, whereas from 2001 to 2018, this figure grew to about 55.9 million acres. … In spring 2020, Jimy Dudhia, a scientist at the National Center for Atmospheric Research, asked us whether established relationships between climate and fire can be used to forecast fire activity accurately. This question ignited our curiosity, fueling research to find out whether weather in the winter and spring can reliably predict the severity of the fire season the following summer. … ”  Read more from EOS here:  For western wildfires, the immediate past is prologue

A case for retreat in the age of fire

Wildfires in the American West are getting larger, more frequent and more severe. Although efforts are underway to create fire-adapted communities, it’s important to realize that we cannot simply design our way out of wildfire – some communities will need to begin planning a retreat.  Paradise, California, is an example. For decades, this community has worked to reduce dry grasses, brush and forest overgrowth in the surrounding wildlands that could burn. It built firebreaks to prevent fires from spreading, and promoted defensible space around homes.  But in 2018, these efforts were not enough. The Camp Fire started from wind-damaged power lines, swept up the ravine and destroyed over 18,800 structures. Eighty-five people died.  Across the America West, thousands of communities like Paradise are at risk. … ”  Read more from The Conversation here:  A case for retreat in the age of fire

Gov. Gavin Newsom asked California to conserve water voluntarily. Guess how that’s going

California’s largest reservoirs may be half-empty or worse, but state officials strove to portray the latest lackluster water conservation data in glass-half-full terms. The results nevertheless continue to show that a year after Gov. Gavin Newsom set a voluntary water conservation target, Californians are broadly volunteering to ignore it. Urban consumers used about 3% less water in May than they did two years ago, well short of Newsom’s goal of conserving 15% more than in 2020. The Sacramento region did slightly worse than the statewide average in the latest available data, consuming 2.4% less.  The month did constitute a dramatic improvement over the relative binge of the previous two months, when Californians used about 18% more water than they did during the same period in 2020. … ”  Read more from the Sacramento Bee here: Gov.

Working together is key to protecting groundwater

Paul Gosselin, deputy director of the Sustainable Groundwater Management office at the California Department of Water Resources, writes, “Nearly eight years ago, during our last severe drought in 2014, the Legislature took bold action to enact landmark groundwater legislation known as the Sustainable Groundwater Management Act, or SGMA. Less than a decade later, the West is experiencing continued historic drought impacts that have researchers claiming this to be the most gripping drought in over 1,200 years.  While they may be out of sight and underground, California’s groundwater basins are a critical part of our state’s water supply, providing about 40% of the state’s supply in average years and up to 60% in dry years, like the severe drought conditions we’re currently experiencing.  Millions of people across the state depend on groundwater for their drinking water, business and irrigation needs. Much of California’s vibrant agricultural production relies on groundwater. The sustainability of California’s groundwater is critical to California agriculture, communities and environment. … ”  Read more from Ag Alert here: Commentary: Working together is key to protecting groundwater

The case for banning front lawns in California is stronger than ever

Dennis Wyatt, editor of the Manteca Bulletin, writes, “Man-made climate change is not the source of California’s water woes.  I guarantee that some people will read those 11 words and dismiss anyone who utters them as a climate change denier or at least a member of the Flat Earth Society.  But the science and history are absolutely clear that when it comes to our water supply we are basing our solutions on the wrong facts.  The biggest lake in California just 173 years ago — Tulare Lake — no longer exists. It covered an area that was larger than Clear Lake — the largest body of water self-contained in California — and even drawled Lake Tahoe that straddles the California-Nevada border.  Early in the 20th century before Los Angeles sucked it almost dry, Owens Lake was 12 miles long, 8 miles wide with water depth ranging from 23 to 50 feet cover 108 square miles.  Tulare Lake did not disappear because of man-made climate change nor did Owens Lake dry up because of it. … ”  Read more from the Manteca Bulletin here: The case for banning front lawns in California is stronger than ever

STATE WATER BOARD: Update on the Strategy to Optimize Resource Management of Stormwater (STORMS) program

Traditionally, stormwater was viewed as a flood management problem in which the runoff needed to be conveyed as quickly as possible away from urban areas and ultimately into waterways to protect public safety and property.   Consequently, stormwater was considered a problem and not a resource.

However, in recent years, stormwater management has been receiving more attention as drought has put more pressure on water supplies, and municipal governments have been held increasingly responsible for pollutants washed from urban areas within their jurisdictions that are discharged into waterways.

In 2016, the State Water Board adopted a stormwater strategy to develop innovative regulatory and management approaches to maximize opportunities to use stormwater as a resource.  At the June 21st meeting of the State Water Resources Control Board, staff updated the Board members on the Strategy to Optimize Resource Management of Stormwater (STORMS) program.

The crisis of the Colorado River system

Lake Powell, July, 2021. Photo by Jay Huang

It should be obvious to anyone – trying to fill a bathtub with the drain wide open is foolish.  This is precisely what the operators of the Colorado River system (Lakes Powell and Mead) have been attempting to do for the past 20 years. They have disregarded the increased withdrawals by the Lower Basin states (California, Arizona and Nevada) and the ubiquitous arid nature of the Southwest.  The Colorado River system and the Colorado Compact administration was set up with a series of reservoirs, recognizing the aridity of the region and the unpredictable amount of annual precipitation. Most of the water supply for the Colorado River system is supplied by the Upper Basin states – Colorado, Wyoming, Utah and New Mexico. As planned, these states have continuously supplied the required 75-million-acre feet in 10 years, or an average of 7.5 million acre-feet per year. … ”  Continue reading from The Heart of the Rockies Radio here: The crisis of the Colorado River system

How Scottsdale’s drought plan has reduced the city’s water footprint

In front of the Granite Reef Senior Center in Scottsdale, there’s a parking lot on one side, and off to the other side, there’s a space for the Scottsdale Trolley to stop. Between those areas is a patch of gravel and drought-tolerant desert plants. Six months ago, the senior center’s little xeriscape garden was about 3,000 square feet of turf. But it wasn’t intended as a sports field or a picnic area, it was really just a decorative space to divide two sides of the parking lot.  “This area was not an active, usable area of turf,” said Nick Molinari, Scottsdale Parks and Recreation director.  So Molinari’s department realized they could take the grass out and no one would really miss it. Molinari estimates the change will save the city 330,000 gallons of water per year. … ”  Read more from KJZZ here: How Scottsdale’s drought plan has reduced the city’s water footprint

As drought shrivels Lake Powell, millions face power crisis

Alongside Nevada’s Lake Mead, Powell is one of the two largest reservoirs in the nation, holding 24m acre feet of water and spanning the Arizona-Utah border, and together they provide a vital water supply to a combined 40 million people in the south-west. Lake Powell is also a major source of hydropower: the vast pressure of the Colorado River traveling through the Glen Canyon dam’s 15-foot pipes, which spins turbines and then powers eight generators, produces cheap and clean energy for as many as 5.8 million homes and businesses across seven states.  But dwindling water levels at Lake Powell, which is now at 28% of its 24m acre-feet capacity, have put the Glen Canyon dam at risk. In March, water levels fell below 3,525 feet – considered a critical buffer to protect hydropower – for the first time. If the lake drops just another 32ft, the dam will no longer be able to generate power for the millions who rely on it. … ”  Read more from The Guardian here: As drought shrivels Lake Powell, millions face power crisis
