California details path to reintroducing fish into Klamath River

“California officials on Thursday released a plan they say will aid officials in the reintroduction of fish, including the imperiled Chinook salmon, to the Klamath River.  The report’s release came the same week that river, which crosses from southern Oregon to Northern California, became free-flowing for the first time in a century, after the final two cofferdams in California on it were breached.  The main goal of the Klamath River Anadromous Fishery Reintroduction and Restoration Monitoring Plan is to create healthy, self-sustaining fish populations, including Chinook and coho salmon, steelhead and Pacific lamprey. This would bring economic benefits, as well as enhance tribal, recreational and commercial fisheries, the state Department of Fish and Wildlife said.  “The approach outlined in the plan minimizes interruption of natural biological processes to allow natural demographics, ecology and evolution to unfold thus promoting wild fitness, life history diversity and resiliency of these species,” said Charles H. Bonham, director of the fish and wildlife department, in a statement. … ”  Read more from the Courthouse News.

Post-wildfire erosion in California threatens water storage and increases flood risk

Boulders deposited by post-fire debris flow, 2020 Dolan Fire.

“California communities and waterways near scorched hillsides are vulnerable to serious disasters, long after wildfire flames die out. Downpours can wash away millions of tons of soil and rock each year from California slopes, according to a study published this week, led by scientists from the U.S. Geological Survey and California Geological Survey.  Researchers found this postfire erosion has dramatically accelerated across Northern California over the past four decades. Burn scars are especially at risk of debris flows, fast-moving slurries of mud and rock that can destroy homes and wipe out roads. But even smaller trickles can unload soil into waterways and clog up lakes. The researchers reported that across the state, 57% of the material flushed from postfire locations was upstream of reservoirs. … ”  Read more from the San Francisco Chronicle (gift article).

Portantino bill requiring robust study of microplastics in drinking water passes senate, heads to governor

“Senate Bill 1147, authored by Senator Anthony J. Portantino (D – Burbank), passed the Senate floor today and is now headed to the Governor for signature. The bill requires the study of the health impacts of microplastics in drinking water.  “With increased reports and interest on the health risks of microplastics, it is past time we formally study its impacts,” stated Senator Portantino. “SB 1147 calls for the identification of a level of microplastics in drinking water that do or don’t pose risks to our health and then initiates a strategy to make drinking water safer for consumption. The bill applies to both tap and bottled water, which will ensure that all drinking water is treated consistently to maximize public health.”  … SB 1147 would require the Office of Environmental Health Hazard Assessment (OEHHA) to share biennial studies that explore the health impacts of microplastics in drinking and bottled water to evaluate toxicity characteristics and identify levels of microplastics that are not anticipated to cause or contribute to adverse health effects, or to identify any data gaps that would need to be addressed to establish those levels. After considering the findings of the report, the State Water Resources Control Board (SWRCB) may request OEHHA prepare and publish a public health goal for microplastics in drinking water. … ”  Read more from Senator Portantino.

Friedman bill to protect California’s wetlands following supreme court decision passes the California legislature

“Last year, the United States Supreme Court decimated protections for the nation’s wetlands. Assemblymember Laura Friedman’s (D-Burbank) landmark bill, AB 2875, which protects California’s vital natural resources from the rollback of federal protections. Yesterday, the bill passed the California Legislature with a vote of 76-0.  Wetlands are vast but delicate webs of interdependent species and complicated geology akin to rainforests or coral reefs. California was once flush with wetlands, the brimming tidal lands, riparian habitats, and seasonal vernal pools once covered more than 4 million acres throughout the state. Wetlands, while crucial habitat for California’s native species, have been nearly eradicated in the Golden State. A mere 10% of California’s wetlands including 5% of its tidal wetlands, still exist, choice waterfront property that developers dream of selling for top dollar. … ”  Read more from Assembly member Laura Friedman.

California Proposition 4: Funding climate action

WE GROW CALIFORNIA: Call to action: Fall X2

Darcy V is harvesting tomatoes so that means, Darcy B. is leading this discussion, and what a discussion it is! Darcy welcomes Geoffrey Vanden Heuvel, the Director of Regulatory and Economic Affairs for the Milk Producers Council, a California dairy farmer trade association. Geoff is currently the Vice-Chairman of the Water Blueprint for the San Joaquin Valley Board. Geoff joins Darcy B in the studio where they discuss the urgent Fall X 2 Action.  The Fall X2 Action (Technically it addresses salinity intrusion in the Bay Delta), as currently mandated, results in significant water supply reductions that provide water for the San Joaquin Valley’s agricultural industry, rural communities, including disadvantaged communities, Southern California cities, families, industry, and economies, as well as critical habitat in both federal and private wildlife refuges.


WHAT MATTERS: All about the Delta Conveyance Project

Imagine a future where California faces increasing water instability. The state experiences more rain, less snow, and an uptick in extreme weather events like droughts and floods. Layer in the looming threats of sea level rise, climate change, and seismic activity, and the picture becomes even more complex.  Now, consider a solution designed to tackle these challenges head-on—the Delta Conveyance Project. This ambitious, multi-billion-dollar initiative aims to enhance water reliability for 27 million Californians by modernizing the water transport infrastructure within the Sacramento-San Joaquin Delta. But what does this mean for the environment, local communities, and California’s long-term water security?

Restoration redefined: meadow recovery and climate action join forces in the Sierra Nevada Glass Mountains

“About 70% of Sierra meadows are degraded, with diminished capacity to hold water or store below-ground carbon. Similarly, vast tracts of forest where dead and dense tree stands predominate are vulnerable to catastrophic wildfire, counteracting their carbon benefits. CalTrout is developing a new approach to meadow and forest health in the Sierra Nevada – we are transforming meadow and forest restoration efforts into quantifiable carbon, water, and energy benefits on a landscape scale. This differs from traditional approaches which address only one or two primary causes of ecological degradation limited to the immediate project area, neglecting efficient use of restoration byproducts, facilitation of atmospheric carbon-reduction, and connecting local communities with sustainable energy resources.  CalTrout recently received funding from the Sierra Meadows Partnership to start implementing this bold initiative through a pilot program in the Glass Mountains. This remote location possesses a unique combination of all features needed for the project. … ”  Read more from CalTrout.

What threat does lead poisoning pose to Oakland Unified students?

“The Oakland Unified School District is grappling with high lead content found in water at some of its schools. The heavy metal is toxic and hazardous to human health.  Here what you need to know about lead.  Q: What is the safe amount of lead in drinking water?  A: There is no safe amount of lead in drinking water, according to Asa Bradman, a professor of public health at the University of California Merced. Federal and state law caps the amount of acceptable lead in drinking water at 15 parts per billion, but some school districts have enacted policies to further restrict that limit, including Oakland Unified which has a limit of 5 ppb and Berkeley Unified which has a limit of 1 ppb. … ”  Read more from the San Jose Mercury News.

San Jose looks to make Lake Cunningham safe for swimming again after feds chip in $850,000

“For many longtime East Side residents, Lake Cunningham holds a special place in their hearts — and San Jose Councilmember Domingo Candelas is no exception.  He learned to swim at the 50-acre, man-made lake and made many more memories frequenting the 203-acre park with his family, friends and neighbors.  But over the past several decades, the water quality has deteriorated so badly that the lake’s become an environmental disaster, with swimming long banned. After years of neglect, San Jose is seeking to restore the lake to its glory days.  And the federal government has given Lake Cunningham some hope. U.S. Rep. Jimmy Panetta has secured $850,000 in funding to help improve water quality, with the ultimate goal of making the lake usable for the first time in nearly 30 years. … ”  Read more from the San Jose Mercury News.

Sunnyvale officials delay vote to ban artificial turf

“The debate between using artificial turf or natural grass on government-owned athletic fields in Sunnyvale has been pushed into the future, leaving environmental activists and youth sports groups in limbo.  The Sunnyvale City Council declined to decide on banning artificial turf after a 4-2 vote, with Mayor Larry Klein and Councilmember Richard Mehlinger dissenting and Councilmember Alysa Cisneros absent. Instead, councilmembers will wait about a year and half for the city to finish its study on the environmental effects of artificial turf versus natural grass before reconsidering a ban.  Sunnyvale Alliance Soccer Club President Damon James said he is disappointed by the delay, which affects efforts by the club’s youth sports group to get better quality athletic fields. He added that delaying a decision doesn’t feel like a response to the demands of environmental groups, such as the Sierra Club. … ”  Read more from the San Jose Spotlight.

Morgan Hill hikes waste water rates, raising affordability concerns

“Despite some worries over the cost to residents, Morgan Hill City Council voted Wednesday to raise wastewater rates by 9% in October, with additional hikes each of the following three years.  Under the plan, residents would be paying nearly 50 percent more than the current rates by 2028.  “This will hopefully allow us to operate and maintain the system to provide the services that the residents want,” said Dat Nguyen, finance director for the city of Morgan Hill. Nguyen stressed that the city was not allowed to charge more than it costs to maintain the system, and that the hike was necessary for the system to operate safely. … ”  Read more from the San Jose Mercury News.

Alternative to controversial plan to bury contaminated sediment in Newport Harbor gains traction

“Environmentalists claimed victory this week over a stalled plan to bury contaminated sediment in Newport Harbor and applauded an alternative proposed earlier this month that would repurpose it for a pier expansion program in Long Beach.  But city officials say both options are still on the table.  The sediment would be the byproduct of dredging the harbor so channels remain deep enough for boats to safely navigate the federally controlled waterways. Newport Beach officials have described the substance as nontoxic. But samples from the bottom of the harbor have tested positive for trace amounts of harmful chemicals including mercury, polychlorinated biphenyls (PCBs) and the pesticide dichloro-diphenyl-trichloroethane (DDT). … ”  Read more from the LA Times.

Listen: What do more water cuts in 2025 mean for Las Vegas and Nevada?

“Even though it still gets over 100 degrees, and forecasters say it’ll stay there for another week or so, right now … we’re all breathing a sigh of relief.  Because the summer’s awful summer heat seems over.  How bad was it? Even those few born here weren’t doing their usual boasting about how the heat was nothing. This summer was something altogether different. It was starting to break people, and it killed dozens.  To make matters worse, the news came a few weeks ago that Las Vegas would once again have cut back on its use of the Colorado River, even though it already has the smallest share of water out of seven states that use the river.  And it’s made us all wonder about our water supply. We can have all the megaresorts we want, but without a steady supply of water, Las Vegas doesn’t exist, or it exists on a much smaller scale.  But is that even a potential future? Will the seven states get their act together and come up with enough river cuts that we can stop worrying for a while?”  Listen at NPR.

Lake Powell: Water rule change could have saved 28.5 billion gallons

“As Lake Powell and other vital water sources in the Colorado River Basin face increasing stress, researchers are calling attention to a simple yet critical legal reform that could help secure the region’s water future.  A recent study by a consortium of scientists, including experts from the University of Virginia, suggests that closing Colorado’s “free river conditions” loophole could play a key role in stabilizing water supplies and safeguarding reservoirs like Lake Powell.  The loophole is a remnant of historic water-sharing agreements between the seven states, 25 Native American tribes and parts of Mexico that rely on the Colorado River—some 40 million people. It allows anyone in Colorado to divert unlimited water from the river when it carries enough to meet everyone’s needs, regardless of their water rights.  “Closing this loophole in Colorado’s water rights system could save millions of cubic meters of water and be the state’s modest contribution to solving water stress in the Colorado River Basin,” lead author Peter Debaere said in a statement. … ”  Read more from Newsweek.
