Kayaking to Hawaii

After a French-American resident of Larkspur helped row a small boat from Monterey to Hawaii in 2016, he vowed he’d never undertake such a journey again. But Cyril Derreumaux spoke too soon. “My imagination took off, and I started dreaming about doing the same trip again in a kayak,” he says. Now, after several years of planning, Derreumaux is getting ready to embark. He plans to leave Monterey Bay in a custom-made kayak with no companions in late May and,...

Londons Roam and Feast on the Bay circa 1910

Jack London usually sailed west whenever he left the Oakland Municipal Wharf, but on December 18, 1913, he headed east — because he could. Although the canal connecting the Oakland Estuary to San Leandro Bay had been completed in 1902, it wasn’t until the U.S. Army Corps of Engineers widened and deepened the canal in 1913 that it became navigable. Aboard the Roamer, a 30-foot yawl London bought used in 1910, Jack and his wife, Charmian, approached the Park Street...

Heavy Lifting for Fish

Ted Frink recalls watching Jacques Cousteau’s television specials when he was growing up in coastal Orange County. “I envisioned myself as Cousteau,” says Frink, a fisheries biologist with the California Department of Water Resources (DWR) now approaching retirement. “My folks encouraged my interest in science. I knew I could be a biologist.” That early inspiration sparked a long and varied career, culminating in his work as chief of DWR’s Special Restoration Initiatives Branch and his role in mitigating obstacles to...

Trolling for Salmon by Kayak

Whales scare us much more than sharks. They erupt from the ocean with a rush of displaced water and a poof of air. A collision could be disastrous. “Whale – go-go-go!” I shout. We pedal double-time to dodge the humpback, behind us and approaching from the left. A moment later it surfaces again, with another poof, now off to our right, moving away. We relax and slow back to our standard trolling speed of about 2.5 miles per hour, and...

Parks and Cities Seek Shore Resilience

By Joe Eaton For Alameda County, climate vulnerability is no abstraction. King tides push the waters of San Leandro Bay into parking lots at Martin Luther King Regional Shoreline. When Diablo winds rattle the eucalyptus, Berkeley and Oakland hill-dwellers recall the conflagrations of 1923 and 1991 and dread the next one. The county feels the bite of both edges of the climate sword: fire and flood. With highways, BART, a major airport and seaport, business parks, and sports complexes, the...

Greener Fatter Levees Boon to Richmond Resilience?

By Daniel McGlynn In May, despite the now normal issues of groups gathering for video calls and virtual PowerPoints, the San Francisco Bay Restoration Authority voted unanimously to fund the early stages of a massive new infrastructure project along the North Richmond shoreline with a grant of $644,709. The shoreline is now one step closer to becoming home to a horizontal, or living, levee that provides both flood protection and habitat. The proposed project, in the planning stages since 2017,...

Tending the Urban Earth and Its People

While most activities ground to a halt in the COVID-19 crisis, nature didn’t skip a beat at urban farms across the Bay Area. Urban farms meet an array of local needs, whether it’s for organic food, living wage jobs, a community center, or a place to connect with nature. With the COVID crisis, and with many American communities touched by loss and fighting racism, these needs have become even more acute. Farms, gardens, and nurseries across the Bay Area are...

Squeezed by Geography

By Nate Seltenrich In most respects, Marin County is a privileged place. It ranks first in the Bay Area for income per capita and includes many of the region’s priciest zip codes. But its miles of Bay and ocean shoreline and many low-lying towns, positioned to afford easy coastal access and world-class scenery, represent a major liability in the era of sea-level rise. “Marin is the canary in the coal mine in some ways, because almost everything is in that...

Time Travel on the Bay

By Aleta George “In day-to-day life we look at the world in a three-dimensional view,” Liam O’Donoghue, host and producer of the award-winning podcast East Bay Yesterday, says, “but when you know history, you can look at it through four dimensions because you can see into the past using your imagination.” On a recent boat tour of the East Bay shoreline led by O’Donoghue, Captain Andy threaded his vessel Pacific Pearl through the Berkeley pier as if it were a...

Dennis McEwan finished work on the 430-acre Yolo Flyway Farms Tidal Habitat Restoration Project in September 2018. A month later, he retired.

The timing was no accident; he’d delayed his departure from the California Department of Water Resources (DWR) to see the project through after helping to launch it ten years earlier. But even from the very beginning of his career, McEwan had been committed to doing all he could for declining species in and around the Delta. That “calling,” as he put it, began with 25 years at the California Department of Fish and Game (now Fish and Wildlife) supporting Pacific...

A career spent monitoring imperiled fish has given Randy Baxter a strong sense of the vulnerability of aquatic ecosystems.

“We’ve overtaxed the system,” he says. Baxter officially retired from the California Department of Fish and Wildlife last August, but still works two or three days a week as a “reemployed annuitant”—a big change from supervising a staff of 14 studying the threatened longfin smelt and other native fish. The reduced schedule gives him more time to fish, in California and on British Columbia’s Skeena River, and tend his orchids and carnivorous plants. Chicago-born Baxter grew up in Pacifica with...

Jan Thompson has always been most interested in what happens down at the bottom of the Bay.

The zone of interaction between the critters in the oozes and the water column above—where specks of sediment, nutrients, and fish food cycle through clam siphons into the Estuary—is the particular specialty of this US Geological Survey scientist. “I’m most proud of the research I’ve done establishing a solid connection between bivalve grazing and phytoplankton growth,” she says. When USGS first hired Thompson, who retired in October 2019, most women in the Menlo Park office were secretaries. She’s since trained...

After nearly 30 years in refuge management on public lands, Anne Morkill is leaving government, but not wildlife, behind.

Following her February 2020 retirement from managing the San Francisco Bay National Wildlife Refuge Complex, which she led for nearly a decade, Morkill is taking the helm at the Laguna de Santa Rosa Foundation, a nonprofit that stewards one of the largest freshwater wetlands complexes on the northern California coast. Morkill believes that San Francisco Bay provides unusual potential for restoring habitat for wildlife in a highly urban environment. “That’s what makes it so special,” she says, citing the Bay...

Bob Fujimura spent his entire career with the California Department of Fish and Wildlife.

Bob Fujimura spent his entire career with the California Department of Fish and Wildlife. From 1987 until his retirement in late 2018, Fujimura served in a variety of roles at the department—but he is likely best known for heading up its long-term monitoring of native fishes in the Bay and Delta. Beginning in the mid-2000s, he oversaw annual smelt surveys with far-reaching implications for management and conservation, including the Spring Kodiak Trawl, which determines the relative abundance and distribution of...

“The Bay is a jewel ― can you imagine if it stunk like it did in the ’50s or if it was green with algae?” asks retiring Executive Director of the Bay Area Clean Water Agencies (BACWA) David Williams, reflecting on his work over much of the last decade to address nutrient pollution.

Working with the 37 wastewater treatment plants that discharge into the Bay, as well as with the San Francisco Bay Regional Water Quality Control Board, Williams helped establish a science-based regional permit for nutrients from the plants. The forward-thinking permit includes nature-based solutions like using wastewater to nurture horizontal levees or create wetlands, buffering the Bay shore from crashing waves as the sea rises. “We have a very enlightened Water Board,” Williams says, “because of that, instead of fighting, the...

Rainer Hoenicke is optimistic about the changes he saw in his five years as the Delta Stewardship Council’s Science Director.

“People are coming to the table and realizing we need to be anticipating and forecasting how to adapt,” he says. Prior to joining the Science Program, Hoenicke served for nearly a decade as deputy and executive director of the San Francisco Estuary Institute, where he managed two Boards of Directors and reorganized the Institute’s program areas. “I felt challenged to do something different,” he says of the move, “since the Delta is much more controversial territory.” In Hoenicke’s eyes, the...
