The new ways California is meeting the growing needs for water in the state

Water in California is sometimes referred to as liquid gold. It makes our cities and towns livable, but it’s getting harder and harder to meet the state’s water needs.  Reliability of water access is becoming one of the greatest challenges the state faces as the climate change alters the already extreme variability in California’s weather.  In fact, the state has long held the top spot for the most variable weather conditions in the nation going from drought to record amounts of rain and snow. One year the state could see only 20 inches of rain, but the next could get 60.  … ”  Read more from Channel 10 here: The new ways California is meeting the growing needs for water in the state

Hurtado no longer calling for State Water Board to be dissolved

State Senator Melissa Hurtado, D-Sanger, will no longer seek to dissolve the State Water Resources Control Board, which manages the state water.  But Hurtado is still moving ahead with Senate Bill 1219 — the State Water Resiliency and Modernization Act. The act originally called for the State Water Resources Control Board to be dissolved and to be replaced by a Blue Ribbon Commission.  That Commission would have been comprised of officials from water agencies across the state along with State Legislators. But Hurtado has placed amendments to the bill which no longer calls for the State Water Resources Control Board to be dissolved. … ”  Read more from the Porterville Recorder here: Hurtado no longer calling for State Water Board to be dissolved

Judge temporarily halts controversial Kings Co. water pipeline

Construction on a controversial water pipeline in Kings County has, once again, halted.  Earlier this week, a Kings County Superior Court Judge ordered a preliminary injunction on the pipeline owned by Sandridge Partners and Santa Clara County’s John Vidovich, as first reported by SJV Water.  Sandridge Partners is attempting to install a pipeline that is 48 inches in diameter that is part of a larger interconnected conveyance system that will run from north of Highway 198 west of Lemoore to the Blakeley Canal, south of Stratford. … ”  Read more from the San Joaquin Valley Sun here: Judge temporarily halts controversial Kings Co. water pipeline

Ongoing drought demands updated models to better manage California’s water

This year’s Sierra Nevada snowpack is just 39% of average. But it’s now more than the amount of snow and rainfall that determines California’s water supply.  Scientists say climate change has created a cycle of drought that is increasingly hard to reverse, and new models are needed to be able to fully meet the West’s water management needs.  “One of the issues that we’re always concerned about with these types of extended droughts or particularly warm periods is that the soil itself will dry out and almost lose its ability to retain water,” said Dr. Andrew Schwartz, lead Scientist and station manager at the Central Sierra Snow Laboratory at UC Berkeley. “Or in another case, depending on your soil type, can actually pull up so much of the water from any new rainfall that it doesn’t make it into streams and then our reservoirs. And so as a result, the drought is kind of, in a way, self-perpetuating.” … ”  Read more from KPBS here: Ongoing drought demands updated models to better manage California’s water

Study examines financial risks of water resilience planning in California

Partnerships between water utilities, irrigation districts and other stakeholders in California will play a critical role in funding new infrastructure under the Water Resilience Portfolio Initiative announced in 2020 by Gov. Gavin Newsom, but a new study warns that benefits might not be evenly distributed without a proper structure to the partnership agreements.  California’s initiative is a multi-billion dollar effort that encourages different water utilities and irrigation districts to work together to build shared infrastructure to reduce the effects of droughts, but a number of questions remain regarding how best to structure these agreements.  In a new research article published March 15 in the journal Earth’s Future, researchers from the University of North Carolina at Chapel Hill and Cornell University explored partnership agreements in the context of the Friant-Kern Canal, which delivers water to irrigation districts and municipal utilities in the southern Central Valley of California. … ”  Read more from Cornell University here: Study examines financial risks of water resilience planning in California

Scientists develop new method to monitor underground water loss in California’s Central Valley

A team of California scientists have developed a new method for monitoring underground water levels on a month-to-month basis.  Eight researchers from NASA’s Jet Propulsion Laboratory in Pasadena and the Berkeley Lab spent the last few years studying the Tulare Basin in California’s Central Valley, an incredibly productive area of farmland that grows roughly 40% of the fruits, vegetables, and nuts in the United States. That productivity is only possible by extensive groundwater pumping, since the region only receives five to 10 inches of rainfall every year.  “After decades of pumping, underground water resources are dwindling,” JPL said in a press release. “Wells in the Tulare Basin now must be drilled as much as 3,500 feet deep to find adequate water.” … ”  Read more from the Courthouse News Service here: Scientists develop new method to monitor underground water loss in California’s Central Valley

Disappointing rain and snow mean tighter water rules ahead

California’s wet season wrapped up as a big disappointment, setting the stage for a third year of drought.  Most of the state — about 96% — was categorized as having severe drought conditions as March came to a close, according to the U.S. Drought Monitor. The continuing drought suggests more water restrictions are forthcoming as supplies run low.  “You need no more evidence than standing here on this very dry landscape to understand the challenges we’re facing in California,” said Karla Nemeth, director of the state Department of Water Resources, at the agency’s April snow survey in the Sierra Nevada, where there was very little snow to measure. … ” Read more from the San Francisco Chronicle here: Disappointing rain and snow mean tighter water rules ahead

Snow drought hits most of the west for the second straight year and California for the third straight year

Snow drought conditions remain widespread across the West and have generally become more severe over the past month. A lack of precipitation was one of the main drivers, with March bringing only about 25%–50% of normal precipitation to the Sierra Nevada, northwestern California, southern and eastern Oregon, and the Great Basin. Except at the highest elevations, the start of April typically is associated with peak snowpack and the start of the snowmelt season, making recovery from snow drought difficult if not impossible at this point in the water year. … ”  Read the full drought update from NIDIS here: Snow drought hits most of the west for the second straight year and California for the third straight year

‘Vast majority’ of California’s Sierra snowpack could be gone by mid-to-late April

California’s worsening drought could disrupt hydropower electricity generation this summer

California’s drought is getting worse — and the drying lakes and reservoirs could severely disrupt the state’s ability to generate electricity ahead of the hot summer months.  California’s energy commission says the state gets 10% of its electricity from power plants at dams along lakes and reservoirs. But when there’s no water, those plants are unable to generate power.  “As we have the continued drought, the availability of hydropower in California has been significantly undercut,” power grid expert Steven Weissman said. … ”  Read more from CBS News here: California’s worsening drought could disrupt hydropower electricity generation this summer

$200 million is flowing to the valley to fix sinking canals

The first releases from a two-year, $200 million state initiative are flowing to the San Joaquin Valley to repair sinking leaky canals.  The 116-mile Delta-Mendota Canal, which has been damaged by land subsidence, will receive $3.3 million for fixes from the state Department of Water Resources.  “Investing in water infrastructure and restoring key water conveyance systems to protect California’s water supply is crucial to climate resiliency,” said DWR Director Karla Nemeth in a news release Thursday. “With California in a third year of drought, this local, federal, and state collaboration is an important step to improving California’s water system.” … ”  Read more from GV Wire here: $200 million is flowing to the valley to fix sinking canals

Reclamation updates CVP allocations and operations

The U.S. Bureau of Reclamation (Reclamation) recently announced adjustments to water operations related to the Central Valley Project (CVP). After an exceptionally dry start to 2022, Reclamation has updated CVP allocations for municipal and industrial water service contractors.  Initial CVP water supply allocations called for a 25 percent allocation for municipal and industrial water service contractors south-of-delta. As of April 1, those contactors have been reduced to Public Health and Safety. Limited northern California water storage had already resulted in a Public Health and Safety allocation for north-of-Delta municipal and industrial contractors. … ”  Read more from Ag Net West here: Reclamation updates CVP allocations and operations

Central Valley water canals to be covered with solar in experimental pilot project

But soon, irrigation canals and aqueducts could help power thousands of California homes and businesses as well, thanks to an experimental project launched by the Turlock Irrigation District to cover them with solar.  “Yeah, I mean, at the most basic level, we are studying how do you span canals that go from 20 feet to 110 feet, and put solar over the top of them,” explained Josh Weimer with the district. … ”  Read more from KGO here: Central Valley water canals to be covered with solar in experimental pilot project

California bracing for what could be another bad fire season. What to expect as weather warms up

Much of California is already in wildfire season after an extremely dry winter left vegetation brittle and water levels low.  With winds and hot temperatures in the forecast starting this week, and no rain or snow expected in the near future, conditions aren’t likely to improve, fire experts said.  Statewide, firefighters battled 925 fires from Jan. 1 to April 1 — about the same as those dates in 2021, according to the California Department of Forestry and Fire Protection. However, the acreage destroyed this year is almost double what burned during those months last year. … ”  Read more from the Redding Record Searchlight here: California bracing for what could be another bad fire season.

How mountain streams signal climate change

A new tool can better assess an important but overlooked indicator of global warming: the variety of bugs, worms, and snails living in high mountain streams.  Water-based invertebrates are especially vulnerable when the climate swings from historic droughts to massive floods. Because they serve as food for other forms of alpine life, such as birds, bats, frogs and fish, ecologists worry about the insects’ ability to thrive.  Understanding how these small creatures are affected by climate change requires understanding where we ought to find them. Yet, classic ecological theories did not account for what a team of UC Riverside ecologists and their UC collaborators found on a recent survey of aquatic life in California’s Sierra Nevada. … ”  Read more from UC Riverside here:   How mountain streams signal climate change

Today’s world is full of uncertainties. Your food supply shouldn’t be one of them

The California Farm Water Coalition writes, “The war in Ukraine and all the global unrest it is causing has focused American’s attention on just how uncertain a world we inhabit.  Inflation was already wreaking havoc on family budgets and now gas prices are also skyrocketing.  Which is exactly why our government should be doing everything it can to reduce reliance on foreign sources for our basic needs, especially food.  Unfortunately, that is the exact opposite of what is happening.  Through out-of-balance regulatory policies and a failure to prioritize western farming, our government is putting our safe, affordable, domestic food supply at risk. … ”  Read more from the California Farm Water Coaliton here: Today’s world is full of uncertainties.

Smart land use planning, not courts, key to wildfire safety

Tiffany Yap, DEnv/PhD, a senior scientist at the Center for Biological Diversity, writes, “California’s startling reminder that its wildfire season is indeed year-round came at the end of January.  The Colorado Fire tore through Monterey County, coming uncomfortably close to the iconic Bixby Bridge. Just weeks after parts of the state saw record snowfall, fire personnel rushed to contain the nearly 700-acre blaze.  Since then, multiple fires have ignited throughout the state, including a 4,000-acre blaze in the Owens Valley. As this winter dry spell continues, we are reminded that the wildfire season has become a wildfire constant. … ”  Read more from Capitol Weekly here: Smart land use planning, not courts, key to wildfire safety

Water is the new carbon

Jay Famiglietti, Jose Ignacio Galindo, Palash Sanyal, and Li Xu write, “When it comes to acknowledging society’s impact on climate, environment, and human security, water is the next frontier for comprehensive accounting and adaptation strategies — for industry, municipalities, governments, and individuals, all of which have made impressive commitments and progress to track carbon pollution.  However, our increasingly threatened global water security demands that accounting for water use and risk rapidly acquire the same urgency with which we address carbon.  The paths of our water and climate journeys have led us to one abundantly clear realization. Since industry accounts for over 80 percent of water withdrawals worldwide, it will be impossible to significantly move the needle on global water security without deep engagement by the private sector. This will require new strategies by industry and investors for valuing and protecting water, the ecosystem services it provides, and its cultural importance. ... ”  Continue reading at the Circle of Blue here: Water is the new carbon

Scotch broom: challenged and destroyed

On March 30, 2022, 11 people met to tackle one of the most pervasive enemies of the watershed: scotch broom.  If you don’t know what scotch broom is, there’s a pretty good chance you’ve seen it while driving through Nevada City or the surrounding areas. It’s frequently along roads and in areas where soil has been disturbed, and while it may be pretty, it is a major nuisance.  Scotch broom was first introduced to the U.S. in the 1800s when it was used as packing material for precious goods being shipped from Europe. It was then marketed as a lovely garden plant in the 1950s that you could buy at your local grocery store. From there, it spread wildly. … ”  Read more from the South Yuba River Citizens League here: Scotch broom: challenged and destroyed

Nevada County commentary: Much needed in Plan for Water

Bruce Herring, a member of The Union’s editorial board, writes, “The next stage of the Plan for Water on April 19 is all about watershed. of the NID mission statement, which will be revisited in the subsequent stage, reads as follows: “The district will provide a dependable, quality water supply; continue to be good stewards of the watersheds, while conserving the available resources in our care.”  The primary source of NID water is the headwaters of the Middle Yuba. That water is stored in Jackson Meadows Reservoir and then transferred across multiple basins into the South Yuba, Deer Creek, and the Bear River. Much of this area also lies within the Tahoe National Forest. And a great deal of the water usage and infrastructure is controlled by PG&E.  It is thus imperative that any discussion of watershed stewardship and health of the resource include cooperation with these two entities. A collaborative effort across agency/government/NGO is essential for proper stewardship on a watershed-wide basis, and circles back to an earlier piece I wrote on integrated water management. … ”  Read more from The Union here:  Nevada County commentary: Much needed in Plan for Water

Why desalination won’t solve Baja California’s water woes

Severe drought in the US southwest is affecting northern Mexican states like Baja California, which depends on water it receives from the Colorado basin under a 1944 treaty.  Rather than building a desalination plant, as authorities proposed, Alfonso Cortez, an environmental researcher at Colegio de la Frontera Norte in Mexicali, suggests measures to produce a surplus, including treatment plants.  “[Desalination] is three or four times more expensive than using treated water or regulating extraction from aquifers. There is also an irrigation system whose water use should be optimized. Why is a desalination plant more expensive than those options? Because it consumes a lot of energy and pollutes the environment,” he told BNamericas. ... ”  Read more from BN Americas here: Why desalination won’t solve Baja California’s water woes
