California’s recent rains won’t end our stubborn drought. These charts show why

California just received more precipitation in the last three months of 2021 than it got in the previous year. The mountains are heaped with historic amounts of heavy snow. But the rain had no sooner given way to sun than state regulators issued new rules forbidding water-wasting practices such as hosing down sidewalks and driveways. What’s going on?  The short version is that, although 33.9 trillion gallons of water have fallen on the state since Oct. 1, that’s not enough to wash away our tenacious drought. Here are some graphics to help to tell the story. … ”  Read more from the LA Times here: California’s recent rains won’t end our stubborn drought. These charts show why

Potter Valley hydropower project license lapse sets stage for plans to remove Eel River dam

The future of a little-known dam on the Eel River in Lake County may be shaped this year as the license expires on a broken-down PG&E hydropower project that plays a critical role in providing water to 600,000 Sonoma and Marin county residents.  Demolition of Scott Dam, a 138-foot concrete structure built a century ago to impound Lake Pillsbury, is an “absolute requirement” for a coalition that includes Sonoma, Mendocino and Humboldt counties interested in picking up the license, said Rep. Jared Huffman, the North Coast congressman.  But the coalition — known as the Two-Basin Partnership — has fallen short on fundraising and planning for the complex and costly process of taking over the project owned and operated by Pacific Gas & Electric since 1930.  … ”  Continue reading from the Santa Rosa Press Democrat here: Potter Valley hydropower project license lapse sets stage for plans to remove Eel River dam

California must stop burying its head in winter snow

The San Jose Mercury News editorial board writes, “When it comes to water conservation, California is burying its head in the winter snow.  Future generations will not look kindly at our leaders’ complete failure to strategically address the state’s water shortages, which will only get worse with climate change.  Two years of some of the worst drought conditions in state history haven’t slowed Big Ag’s demands for more water. Meanwhile, urban users aren’t coming close to meeting Gov. Gavin Newsom’s call to voluntarily cut their water use by 15% from 2020 levels.  On Tuesday, the state reported that the statewide reduction was just 6.8% in November, compared with November 2020. Bay Area residents hit Newsom’s target, cutting water use 20.2%. But Los Angeles, Orange and San Diego county residents increased water use by 0.8%. … ”  Read more from the San Jose Mercury News here: California must stop burying its head in winter snow

Many Californians fear having their water shut off in the new year. That’s unacceptable

Uriel Saldivar, a senior policy associate at Community Water Center, and Nydia Medina, an AGUA Coalition member, write, “For many people, the new year means a fresh start. But for the million-plus California households with overdue water bills, Jan. 1 had a much less pleasant significance: the end of emergency water shutoff protections. Even though the pandemic is still raging, a state water shutoff ban ended on Dec. 31. Unfortunately, the billion dollars in this year’s budget meant to wipe out water debt won’t reach many families who need it. A lot of utilities are opting out of the voluntary debt relief program, leaving customers in a lurch. That means the amount of help available for families struggling financially will be determined by their address rather than their need. That’s unacceptable in a state that recognizes a human right to water and has spent money to help families keep the water on despite COVID-related hardships. … ”  Read more from the Sacramento Bee here: Many Californians fear having their water shut off in the new year.

Here is a plan to create more water for California

Edward Ring, lead proponent of the Water Infrastructure Funding Act of 2022, writes, “Former Congressman Tom Campbell’s recent commentary “Why the delay on critical water storage projects,” published on these pages on January 3, criticized the California Water Commission’s ongoing failure to build the water storage projects that were approved by voters in 2014. There is an answer to the concerns raised by Campbell: The Water Infrastructure Funding Act of 2022, a constitutional initiative proposed for the November 2022 state ballot.  This initiative, currently being circulated for signatures, requires two percent of the state’s general fund be used to construct new water supply projects, and it doesn’t sunset until new projects add five million acre feet per year to the state’s water supply. Two million acre feet per year can come from waste water recycling, another 1 million from conservation programs, and the rest from runoff capture into off-stream reservoirs and aquifers. And to ensure projects are environmentally responsible, it still gives the California Water Commission the final authority over what projects to fund. … ”  Read more from the Daily News here: Here is a plan to create more water for California

Idiocy of Sacramento politicians, climate change fanaticism & watering Bermuda grass in the winter

Dennis Wyatt, editor of the Manteca Bulletin, writes, “We are idiots. Or at least the politicians in Sacramento that relentlessly sound the climate change alarm are.  This is because of a scene depicting an exercise in futility with overtures of self-destruction that played out Monday just a block off Powers Avenue in Manteca.  A man was dutifully hand watering an area of grass in his front yard that was yellow.  Forget the fact it had just rained a few day prior. Ignore the morning frost that points to air heavily laden with moisture. Overlook the top three or so inches of soil that lawns draw water from are moist. And set aside the reality that Bermuda — and similar grasses — often turn yellow in the cold of winter when non-native California grasses that constitute many lawns are a lush green.  That scene undoubtedly was repeated thousands if not tens of thousands of times across California on Monday. … ”  Continue reading at the Manteca Bulletin here: Idiocy of Sacramento politicians, climate change fanaticism & watering Bermuda grass in the winter

Crescent City: Harbor asking permission to dredge swiftly

Battery Point Lighthouse, Crescent City

Members of the Crescent City Harbor Commission may attend a North Coast Regional Water Quality Control Board in February in an effort to advocate for swift dredging of the harbor. On Jan. 4, harbor commissioners also reviewed a draft letter that would be sent ahead of time. According to that letter, harbor commissioners are seeking two outcomes: quick approval to use divers to dredge silt away from Fashion Blacksmith’s synchrolift so the boat-repair business can move boats in and out of the harbor, plus a longer-term solution that calls for further dredging and relocation of previously dredged silt that’s been sitting in the harbor’s dredge ponds since 2013. … ”  Read more from the Daily Triplicate here: Harbor asking permission to dredge swiftly

Toxic coal train bill passes Senate Transportation Committee

Senator Mike McGuire’s legislation to stop one of the largest environmental threats the North Coast has seen in decades — a proposal from a secret, clandestine operation that wants to ship millions of tons of coal through Northern California — passed with bipartisan support in the Senate Transportation Committee today.  “The proposed toxic coal train is an environmental disaster in the making. The midwest coal would travel through the Sierras, across the Golden State through the heart of our thriving communities, ancient redwoods, and directly along the banks of the Eel and Russian rivers which are the main drinking water source for nearly 1 million residents. It is crucial we stop this dangerous proposal – it transcends politics, and I am grateful for the bipartisan support today.” … ”  Read more at Senator Mike McGuire’s website here: Toxic coal train bill passes Senate Transportation Committee

Tulare County looking at SGMA impact on property values

There’s the definite possibility the Sustainable Groundwater Management Act could have a negative impact on farmers’ property values.  So the question is can farmers affected by the SGMA receive relief when it comes to the amount of property taxes they pay. The answer is maybe.  The Tulare County Assessor/Clerk-Recorder’s Office has addressed this issue, stating farmers affected by the SGMA could possibly receive relief when it comes to the property taxes they pay.  The SGMA has placed a requirement in which the pumping of groundwater must be reduced. So the SGMA is obviously impacting the use of agricultural land and in turn is influencing property values.  But as the county assessor has stated: “Quantifying the effects of these changes is an ongoing challenge.” … ”  Read more from the Porterville Recorder here: Tulare County looking at SGMA impact on property values

Grants awarded to restore safe drinking water for Lake Morena residents—but process may take until 2024

For more than two years, Lake Morena Village area water users have been drinking bottled water because of formidable nitrate levels in the region’s wells, the main source of water for drinking in the rural San Diego county burg.  In September 2019, the county issued a do-not-drink order for about 125 customers of the Lake Morena Views Mutual Water Company, one of the two main water suppliers in the area.  The state recently approved grant funds to eliminate the contamination, but the process moves slowly – meaning frustrated residents may be without potable tap water for another two to three years.  “I am wondering what the effects will be on all of us in time to come.

Reclamation modifies monthly water releases from Lake Powell to protect reservoir’s critical elevations

The Bureau of Reclamation began monthly operational adjustments at Glen Canyon Dam on Jan. 1, taking initial steps to protect the reservoir’s target elevation of 3,525 feet. As of Jan. 5, Lake Powell’s water surface elevation measured 3,536 feet, just 11 feet above the target elevation. Without the changes to monthly water releases, the reservoir’s elevation was projected to steadily decline below the target elevation through the winter months. The adjusted releases are designed to help protect critical elevations at Lake Powell until spring runoff materializes.  The monthly volume of water released from Glen Canyon Dam is being adjusted to hold back 350 thousand acre-feet (kaf) of water in Lake Powell from January to April when inflow to the reservoir is low. The same amount of water (350 kaf) will then be released to Lake Mead between June and September after the spring runoff occurs. The annual volume of water released from Glen Canyon Dam is unchanged by these operational adjustments. … ”

Trends in U.S. irrigated agriculture: Increasing resilience under water supply scarcity

Growing urban populations and economic development intensify competition for the nation’s water resources. With surface water supplies largely allocated in most river basins of the Western United States and some river basins in the Eastern United States, emerging water demands from non-agricultural sectors must be met in many cases through a reallocation of water initially allocated to agriculture.  Meanwhile, changing climate regimes — through increased evaporative losses, seasonal shifts in precipitation patterns, reduced snowpack and snowmelt runoff, and higher frequency and severity of droughts — have reduced water supplies during the crop growing season. At the same time, groundwater pumping in excess of natural recharge has substantially diminished aquifer resources critical to agriculture in regions where, and when, surface water is less abundant. Increasing competition for water, coupled with increasingly constrained water supply trends, have important implications for the viability and resiliency of the irrigated agricultural sector. How the sector adapts to these trends will shape the future of irrigated agriculture and the value it creates for the greater agricultural economy. … ”  Continue reading at the Fence Post here: Trends in U.S. irrigated agriculture: Increasing resilience under water supply scarcity

These goldfish learned to drive. Yes, you read that correctly. In a recent study, scientists have successfully trained six goldfish to drive a “fish operated vehicle” (FOV). The study, conducted by researchers at the Ben-Gurion University of the Negev in Israel, aimed to determine the ability of the goldfish to navigate in different environments.  Since goldfish naturally navigate in water, the scientists wanted to see if they could replicate the same ability on land and other environments. To achieve this, they created a small goldfish tank with wheels on it. The vehicle tank used a camera and remote sensing system that allowed the whole apparatus to move based on the direction the goldfish swam. ... ”  Read more from Inhabitat here: These goldfish learned to drive with the help of scientists
