An atmospheric river is headed to the West Coast. Will it hit California?

An atmospheric river was expected to bring heavy rain and flooding across the Pacific Northwest this week, meteorologists said.  Will California and the Bay Area see any rain because of it?  The short answer is no, according to Sean Miller, a meteorologist with the National Weather Service in the Bay Area.  Miller described the weather system in the Pacific Northwest as the first of a “series of big waves that are kind of moving through” the Western U.S. ... ”  Read more from the San Francisco Chronicle here: An atmospheric river is headed to the West Coast.

Sierra Nevada snowpack disappearing after driest January-February in recorded history, third year of California drought all but inevitable

Get ready for more brown lawns, high fire danger and water restrictions this summer.  California’s severe drought, which seemed to be retreating after soaking storms in October and December, is now all but certain to continue into a third year after the driest January and February in recorded history.  “We were so far above normal early in the winter,” said Jan Null, a meteorologist with Golden Gate Weather Services in Half Moon Bay. “But the rainfall season has just flat-lined. It has died.”  On Tuesday, officials from the State Department of Water Resources are scheduled to take a monthly snowpack reading in a media event at Phillips Station, near Sierra-at-Tahoe ski area. Statewide, they already know the news. … ”  Read more from the San Jose Mercury News here: Sierra Nevada snowpack disappearing after driest January-February in recorded history, third year of California drought all but inevitable

Forecasters: ‘Miracle March’ not likely for Tahoe, Sierra as drought continues

It’s been a tale of two winters.  After record-breaking storms pushed Tahoe-area snowpack to 200% of normal on Jan. 1, winter has all but disappeared.  January and February are historically the wettest months for Nevada and California. But this year, many snow-measuring sites in the eastern Sierra recorded the lowest precipitation levels on record for the first two months of 2022. … Heading into March, snowpacks in the Tahoe, Truckee, Carson and Walker basins are sitting anywhere between 77 and 88% of median. In other parts of Northern Nevada, the snowpack is as low as 64% of median. ... ”  Read more from the Reno Gazette Journal here: Forecasters: ‘Miracle March’ not likely for Tahoe, Sierra as drought continues

CA Court of Appeal: Watermaster has no right to appeal trial court orders on water rights decrees

On Feb. 23, 2022, the Third District Court of Appeal issued an opinion in Dow v. Lassen Irrigation Company et al, C091965 as to what it believed to be an issue of first impression—whether a watermaster appointed by the trial court to implement and administer a water rights decree has the right to appeal the trial court’s orders interpreting the decree on the grounds the watermaster disagrees with the trial court’s interpretation and the orders would increase the watermaster’s administrative burdens and costs. In response to respondent’s motion to dismiss, the Court of Appeal, in a published opinion authored by Justice Ronald Robie, held that the watermaster does not have the right to appeal on the grounds that the watermaster is not aggrieved by the trial court’s interpretation of the water users’ rights under the decree. … ”  Continue reading at Brownstein Water here: CA Court of Appeal: Watermaster has no right to appeal trial court orders on water rights decrees

Prop 65 lists PFOA as carcinogen

As we wrote in December, 2021 saw several significant actions taken by the state of California with respect to PFAS – specifically, Prop 65 PFAS determinations for PFOS and PFNA. On February 25, 2022, another significant step was taken when the California Office of Environmental Health Hazard Assessment (OEHHA)  added PFOA to the list of chemicals known to cause cancer. The listing will create new warning label requirements for any product sold in California that contains PFAS, and may also increase enforcement action targeting of PFOA-containing products. Important to note is that the Prop 65 regulations are not applicable only to companies situated in California; rather, they apply to any company (even internet businesses) that sell products to anyone in the state of California. … ”  Read more from the National Law Review here: Prop 65 lists PFOA as carcinogen

Tiny tire particles inhibit growth of organisms in freshwater, coastal estuaries, studies find

Small particles from tires inhibited the growth and caused adverse behavioral changes in organisms found in freshwater and coastal estuary ecosystems, two new Oregon State University studies found.  The findings are part of a continued effort by scientists to unravel the impacts of microplastics and nanoplastics on aquatic ecosystems and aquatic organisms. Tire particles are one of the most common microplastic types in aquatic ecosystems.  Harper, Brander and several other graduate students and a post-doctoral scholars in their labs, including Brittany Cunningham, Samreen Siddiqui, recently published two papers on the tire particle research in Chemosphere and the Journal of Hazardous Materials. ... ”  Continue reading from Oregon State University here: Tiny tire particles inhibit growth of organisms in freshwater, coastal estuaries, studies find

Urban stormwater presents pollution challenge

On the wildest, stormiest nights in the San Francisco Bay Area, scientists from the San Francisco Estuary Institute (SFEI) go out on the prowl. Nighttime is when storm intensity in the Bay Area is generally highest, and the team gets going only when a storm is predicted to dump more than 2 cm over 6 h at a particular site. The researchers fan out to different sites where they know stormwater flow is especially strong. At each site, they take samples to assay the levels of five classes of chemicals: tire- and vehicle-derived chemicals such as 6PPD-quinone; bisphenols, a starting material in manufacturing plastics;organophosphate esters, a key component of flame retardants; per- and polyfluoroalkyl substances (PFAS); and ethoxylated surfactants from paints, coatings, and floor polish. Over several hours, they nab some samples in 50 mL tubes and others in 2 L glass jugs. … ”  Read more from Chemical & Engineering News here: Urban stormwater presents pollution challenge

LAO Report: The 2022-23 Budget: Municipal Stormwater and Urban Runoff Discharges Mandate

The Governor’s budget proposal includes $18.4 million in one‑time General Fund to reimburse certain local governments in Los Angeles County for costs related to the Municipal Stormwater and Urban Runoff Discharges mandate. Specifically, the proposal would reimburse eligible local governments for the costs they incurred installing and maintaining trash receptacles at transit stops between 2002 and 2012 pursuant to regulatory stormwater permit requirements that the Commission on State Mandates (commission) found to be a state‑reimbursable mandate. The state has exhausted its legal options for challenging this particular mandate decision. We therefore recommend the Legislature approve the proposal and fund this mandate, consistent with state law. Funding this mandate does not have out‑year fiscal implications for the state.”  Read the report from the Legislative Analyst’s Office here: LAO Report: The 2022-23 Budget: Municipal Stormwater and Urban Runoff Discharges Mandate

Zero water allocation leaves Central Valley Project farmers with few options

With California entering its third year of severe drought, the U.S. Bureau of Reclamation announced a zero-water allocation for irrigation districts via the Central Valley Project, a 400-mile-long web of dams, canals and other water facilities. The decision will impact farmers in 29 counties across the state’s major agricultural region, likely prompting growers to plant different crops, fallow acres or tear out vineyards and orchards.  “It’s very concerning. Farmers are disappointed, frustrated, angry,” said Tricia Stever Blattler, executive director of the Tulare County Farm Bureau. … ”  Read more from the Capital Press here: Zero water allocation leaves Central Valley Project farmers with few options

Central Valley growers hit by disappointing water allocation

The Central Valley, considered one of the most important agricultural regions in the word, is getting hit hard again by California drought conditions.  The Bureau of Reclamation last week announced a 0% initial allocation for Westlands Water District and Central Valley Water Project (CVP) irrigation contractors. It is the fourth time in the past decade south-of-Delta irrigation contractors have received a 0% allocation, according to a statement from the regional water district. The amount of 2021 rainfall and snowpack looked promising until the past two months, when no water made it down from the Sierras to reservoirs in California. … ” Read more from the Hanford Sentinel here: Central Valley growers hit by disappointing water allocation

Bringing out the best in wild birds on farms

A supportive environment can bring out the best in an individual — even for a bird.  After an E.coli outbreak in 2006 devastated the spinach industry, farmers were pressured to remove natural habitat to keep wildlife — and the foodborne pathogens they can sometimes carry — from visiting crops. A study published today from the University of California, Davis, shows that farms with surrounding natural habitat experience the most benefits from birds, including less crop damage and lower food-safety risks. … ”  Read more from the Western Farm Press here: Bringing out the best in wild birds on farms

Ranking heat waves like hurricanes is being proposed in California

Heat waves are the deadliest weather disaster in the US. They account for nearly 150 fatalities per year, more than hurricanes and tornadoes combined.  New legislation in California hopes to reduce heat-related deaths by ranking heat waves similarly to hurricanes, by using categories and names. However, the National Weather Service (NWS) is currently in a multiyear experiment to also categorize heat waves.  “Globally, people are suffering from heat because of a deadly awareness gap,” said Kurt Shickman, the director of Extreme Heat Initiatives at the Adrienne Arsht-Rockefeller Foundation Resilience Center (Arsht-Rock), which is helping lead the legislative action. … ”  Read more from CNN here: Ranking heat waves like hurricanes is being proposed in California

What winter’s dry spell means for California’s fire season

When rain pummeled California in October, many breathed a sigh of relief: At least in some parts of the state, the worst of the fire season, experts said, was most likely over.  The following month, however, precipitation was scarce. In December, it rained again, smashing records. Now, some parts of the state have barely seen another drop of water since early January.  “It has been both an unusually dry and an unusually wet winter,” said Daniel Swain, a climate scientist at the University of California, Los Angeles, and the Nature Conservancy. … ”  Read more from the New York Times here: What winter’s dry spell means for California’s fire season

Assemblymember Wood introduces bill to improve drought preparedness for North Coast watershed

Assemblymember Jim Wood (D-Santa Rosa) has introduced AB 2451, legislation creating a dedicated Drought Section within the Division of Water Rights responsible for improving drought planning, drought response and climate resiliency statewide, and directing the agency to conduct drought planning for North Coast watersheds.  Existing law establishes the State Water Resources Control Board (the Board) and the regional water quality control boards within the Natural Resources Agency. This Board has two divisions, one for Water Rights and one for Water Quality.  “Drought is not an episodic event and has not been for decades,” said Wood. “They are longer, more frequent, more severe and seriously threaten the health of rivers and streams, the wildlife that inhabit them and the ability to provide our North Coast communities with safe and affordable drinking water.” … ”  Read more from Assemblymember Wood here: Assemblymember Wood introduces bill to improve drought preparedness for North Coast watershed

(Phew! Get all that?)  A dozen years ago developer Anthony Russo began the process of planting 400 houses in rural Middle Green Valley. The houses would be clustered in unobtrusive places; most of the land along Green Valley Road would remain in farming. The valley would maintain its rural look and feel. Not bad.
