New winter storm could push California’s snowpack to record high

“Here we go again. After a several-day break in the rain, snow and wind across California and the West Coast, another intense storm system is poised to slam into the region late Monday night into Tuesday. Heavy snow in the high terrain will make for difficult travel, while heavy rain in coastal, valley and foothill regions could cause flooding. … Ahead of this storm, the amount of water stored in the state’s snowpack had approached or surpassed records in two of three regions. The southern Sierra blew past its previous record in late February and is running 284 percent of the annual normal as of March 27. After this storm hits, the state average could climb to a record high. … ”  Read more from the Washington Post.

With drought relieved, California casts wary eye on snowmelt

“With record and near-record snowpack up and down California, much of its multiyear drought has abated — but it’s never time to break out the balloons and party favors when it comes to water in the West.  During a California-Nevada U.S. Drought Monitoring Group seminar Monday, water experts were upbeat when talking about the massive snowpack, reservoirs spilling and more storms on the horizon.  “Overall, things are looking very good. And so that’s really nice to share after many of these kinds of updates where we tend to look at things going the other direction,” said Ben Hatchett of the Desert Research Institute. “So, the bottom line: Drought conditions have been improving and they continue to improve.”  A substantial portion of California has no drought, although areas still listed as dry to moderately dry include the California desert in the south and uppermost northern California in the southern Cascade Range region near the Oregon border. … ”   Continue reading at the Courthouse News.

Map shows unusual impact California storms are having on the ocean

“While the world’s oceans have hit a record high temperature, the Pacific Ocean off the California coast remains colder than average.  In fact, in virtually no place in the world is the ocean so much colder than normal, according to a map from the National Oceanic and Atmospheric Administration.  “California right now is really a remarkably anomalous outlier,” said Daniel Swain, climate scientist at the UCLA Institute of the Environment and Sustainability, during a press event Monday.  “There is no place on earth right now that has larger negative ocean temperature anomalies than the west coast of North America,” he said.  The stormy weather is clearly a factor. … ”  Read more from the San Francisco Chronicle (gift article).

Farms that haven’t flooded from storms still facing harvesting challenges

“The recent storms have put a dent in the drought, but they’ve also flooded precious farmland, ruining mile after mile of crops across the state. But even at farms that didn’t flood, they are still harvesting challenges.  Thanks to a much-needed assist from Mother Nature this year, Erin Gil’s crops are faring quite well in the Santa Clara Valley. He grows cool-season grass.  “We’ve been doing this since 1969. This is one of the biggest years for rainfall that we’ve had,” he said. “It’s a savior for the state of California.”  However, while the rain has helped his product, it’s hindered his ability to harvest it.  “It is keeping us away from doing all of the things that we normally do,” he said. “A long spell of rainfall means we’re down for a long time without cash flow.” … ”  Read more from CBS Bay Area.

California farmers flood fields to boost groundwater basin

“A field that has long grown tomatoes, peppers and onions now looks like a wind-whipped ocean as farmer Don Cameron seeks to capture the runoff from a freakishly wet year in California to replenish the groundwater basin that is his only source to water his crops. Taking some tomatoes out of production for a year is an easy choice if it means boosting future water supplies for his farm about 35 miles (56 kilometers) southwest of Fresno. He’s pumping 300 acre-feet a day — enough to supply hundreds of households for a year — from the gushing North Fork of the Kings River onto former vegetable fields and others dotted with pistachio trees, which can withstand heavy flooding.  “We knew long-term if we didn’t have water, we’d be out of business,” Cameron said. “We’re doing our part to protect communities downstream, but we’re also putting the water in the ground.” … ”  Read more from US News & World Report.

The biotelemetry boom: Tracking fish movement through time

“Scientists have been tracking and monitoring animals for research since the late 19th and early 20th centuries, primarily by tagging and banding fish and birds with small metal bands. These tags, equipped with unique codes, allowed scientists to identify individuals when they were recaptured. This process aptly referred to as “Mark and Recapture,” provided data that could then potentially be used to estimate population size, migration patterns, behavior, habitat use, and more. While resighting marked birds only requires a pair of binoculars and some patience, recapturing marked fish can be very challenging.  As a result, data from these early efforts were often limited and left scientists with many unanswered questions. However, in the late 1940s and early 1950s, significant electronic advances made it possible for scientists to track animal movements wirelessly and without needing to rely on the physical re-capture of tagged individuals. … ”  Read more from FishBio.

California must provide a global model for coastal resiliency

David Helvarg, an author and executive director of Blue Frontier, writes, “Ten years ago, I wrote a book called “The Golden Shore: California’s Love Affair with the Sea.” Back then, I suggested that California, with almost 40 million people and the world’s fifth largest economy, was proof that you could grow a progressive society while protecting your coast and ocean. The San Francisco Chronicle wrote that the book “just might make you feel optimistic about the future.”  Well, that future has arrived and I’m less optimistic. This winter’s atmospheric river storms, coastal flooding, erosion, sea level rise, saltwater intrusion into rivers, and sedimentation dumping thousands of tons of soil into the ocean were only the most recent of the state’s disasters. The year 2022 alone brought a massive red tide in San Francisco Bay, the continued die-off of 95% of northern California’s kelp forest between the Golden Gate and Cape Mendocino, and a spike of gray whale deaths along the entire coast. … ”  Read more from the San Jose Mercury News.

FEATURE: The Magic of the Mokelumne: How such a small river produces so many salmon

“The Mokelumne River is on the modest side, running 95 miles from the Sierra Nevada and accounting for less than 3% of flows into the Sacramento-San Joaquin River Delta. But the river’s impact on salmon is outsized and the latest figures really made a splash. The California Department of Fish and Wildlife (CDFW) puts the Mokelumne’s contribution to the 2022 commercial ocean salmon fishery at a whopping 51% of the total for hatcheries.

“The Mokelumne is the single biggest contributor to the catch,” says John McManus, president of the Golden State Salmon Association. “It’s huge.”

The Mokelumne River Hatchery’s record is even more impressive given that it raises just a fraction of the young salmon—about 6 million of the 32 million total—produced by Central Valley hatcheries each year.

“It’s punching above its weight,” McManus says. “Why? What’s the magic with the Mokelumne?”

Yurok tribe and fishermen sue to protect Klamath salmon

“Last week, the Yurok Tribe, with the Pacific Coast Federation of Fishermen’s Associations (PCFFA) and the Institute for Fisheries Resources (IFR), sued the Bureau of Reclamation (BOR) to ensure enough water will remain in the Klamath River to protect threatened coho salmon and endangered resident killer whales.  In February, BOR reduced Klamath River flows below the mandatory minimum required to preserve extremely at-risk coho salmon stocks. The water reduction will dry up critical habitat for juvenile coho and Chinook or king salmon. Federal fisheries managers are poised to shut down the ocean commercial salmon fishing season in California due to this year’s dismal Chinook salmon forecast on the Klamath River. The Yurok Tribe will be canceling its commercial fishery for the fifth consecutive year to protect fish runs. … ”  Read more from the Daily Kos.
