Report: Forty years of California water policy: What worked, what didn’t and lessons for the future: Former Executive Director of the Association of California Water Agencies Tim Quinn recounts his extensive career in water policy in this report: " ... Why have some initiatives succeeded, and others failed? Answering this question and discerning the lessons for the water policy of future state and federal administrations is the challenge of this report. One key lesson over recent decades is that in 21st century, California collaboration works and conflict doesn’t. Conflict has played a constructive role in the water management of the past. For example, the decisions to protect the ecological resources of Mono Lake and add environmental values to the purposes of the federal Central Valley Project arose from decision-making processes characterized by high levels of conflict. But over time, circumstances are changing to substantially enhance the importance of collaboration and inclusion in making resource management decisions, especially in controversial and complex policy arenas like California water. ...

Fracking in California gets green light after 9-month pause; Aera Energy receives permits: "California regulators on Friday issued fracking permits for the first time in nine months, saying federal scientists had given clearance for 24 permits to Aera Energy for oil well stimulation in Kern County. Another 282 applications remain on hold pending individual review, until a comprehensive audit of the state's drill permitting practices is completed. "Lawrence Livermore National Laboratory experts are continuing evaluation on a permit-by-permit basis and conducting a rigorous technical review to verify geological claims made by well operators in the application process," said Teresa Schilling, spokeswoman for the California Geologic Energy Management division, or CalGEM. "Permit-by-permit review will continue until the Department of Finance Audit is complete later this year." ...

Will climate change push these amphibians to the brink? "Aerial photos of the Sierra Nevada — the long mountain range stretching down the spine of California — showed rust-colored swathes following the state’s record-breaking five-year drought that ended in 2016. The 100 million dead trees were one of the most visible examples of the ecological toll the drought had wrought. Now, a few years later, we’re starting to learn about how smaller, less noticeable species were affected. ...

March fails to deliver Napa rainfall bailout as dry season approaches: "Napa County had a meager March instead of the hoped-for miracle March on the rainfall front and that could mean one of the driest rainy seasons on record. How about an amazing April? Mike Pechner of Fairfield-based Golden West Meteorology was expecting rain to fall Saturday and Sunday, with showers possible Monday and Tuesday. Some areas could receive more than an inch. Late season rains, while likely too late to turn around an extremely dry rainy season, aren’t too late to make a positive difference. ...

Oceanside harbor dredging finishes early, short of goal: "Health concerns related to the COVID-19 pandemic, along with rough weather, forced this year’s Oceanside harbor dredging project to wrap up earlier than expected, well short of its intended goal of 400,000 cubic yards of sand. The contractor, Manson Construction, pulled up anchor March 21 after dredging about 250,000 cubic yards of material, which is closer to average amount removed most years during the annual spring cleaning of the harbor entrance and channel. “As it got to the end, they went from three shifts, 24 hours a day, down to one shift a day,” said Oceanside Harbor Division Manager Ted Shiafone. “A lot of employees went home to be with their families.” ...

This week in water: "Wet markets are known for selling dead and living animals—and are ripe for infection that can jump to humans. How coronavirus spreads may depend not only on social distancing but also on our indoor environments. "Blue energy" has increased tenfold in the last decade and is set to go higher. There’s an ancient underwater forest off the coast of Alabama that could hold a treasure trove of new medicines. Social distancing will slow the spread of the coronavirus if lobsters are any guide."

How do you study microfibers? Get creative: "Three years ago, Dimitri Deheyn noticed intensely blue stringy shapes as he examined jellyfish samples through a microscope in his marine biology lab at the Scripps Institution of Oceanography at the University of California, San Diego. He assumed his lens was dirty, so he wiped it off with a special cloth. Then he tried taking it apart and airbrushing the optics. But the particles kept showing up. At first, Dr. Deheyn thought the culprit might be microplastics, tiny plastic bits that have invaded the oceans in the past decade. But a quick literature search revealed that the stringy shapes, each about a fifth as wide as a strand of hair, were actually microfibers from fabric. ...

Virus hunters find coronavirus clues in sewage: "Even before it was confirmed by medical tests of infected individuals, the story of the new coronavirus in the city of Amersfoort was being recorded in water. Scientists from KWR Water Research Institute in the Netherlands detected genetic traces of the SARS-CoV-2 virus in wastewater samples from Amersfoort’s sewage treatment plant on March 5, a day before the first confirmed case of Covid-19 in the city. Covid-19 is the disease caused by the virus. That discovery, the researchers say, means that urban sewage systems could function as “a sensitive tool” for monitoring the spread of the virus thorough a city before it is detected in individuals. Similar sewage-sleuthing methods have been used to detect polioviruses or to assess illegal drug use. ... " Read more from Circle of Blue here: Virus hunters find coronavirus clues in sewage
Navigating government regulations in the storm water sector: "As government regulations evolve, municipalities and manufacturers must evolve as well. SWS spoke with Rodney Wynn, who was previously with the Maryland Department of Transportation and is currently working with East Coast Erosion Control to help the team navigate DOT compliance.

Collaboration is the answer to California’s fishery and water supply challenges, says Roger Cornwell: He writes, "California has the opportunity to enter a new era in water management. Unprecedented efforts by leaders at the state and national level have led to the kind of cooperation that will provide valuable benefits to water users and the environment. I know because that’s what we’ve been doing in the Sacramento Valley for many years. The kinds of success we’ve achieved can be replicated in other parts of the state. By working together, we can accomplish much more than can ever be achieved when competing interests are fighting. California’s current water regulatory system is completely broken. Farms, towns and cities suffer continued cutbacks and threatened fish species continue to dwindle. The only recourse currently available seems to be an ongoing parade of lawsuits that further paralyze the system and help no one. ...

Show with the flow: elevation maps reveal world rivers: "These maps of rivers around the world were created by Esri UK, a mapping and spatial analytics company, from detailed elevation data collected using remote sensing techniques. The information was taken from Esri’s Living Atlas, one of the world’s largest collections of geographic information. By eliminating any vegetation or infrastructure, the maps show each river’s geomorphology as it would appear on bare ground. Elevation data can be valuable in highlighting river features and landforms that cannot be seen from normal satellite images, such as slight changes in elevation, run-off, levees, sediment deposits and how the land has changed over time. ...
