Restoration Reflections: A Hundred Ways to Cherish the Estuary

Restoration is a powerful concept. Physically it entails putting something back, making it right again; emotionally it requires hope for the future, a sense of something worth doing.  In the Estuary, restoration is no longer about recreating some pristine ecosystem that once was. The vast marshes that carpeted the Delta and circled the Bay before Europeans arrived out West are long gone; the great rivers spilling fresh water and salmon downstream are a shadow of their former selves; the myriad creeks and sloughs offering migratory paths and habitats for so many estuarine creatures are now laced with obstacles and lined with concrete.  But for some time now, the call to restoration work has been growing. People in all walks of...

Riding the Restoration Waves: My Estuarine Journey

After 16 years of working in the San Francisco Estuary, including serving as a manager for key regional agencies, I have ridden several waves of restoration. I’ve seen big changes in how restoration is done, who does it, and who benefits—whether it’s a fish or bird on the verge of extinction or a young person from an urban community learning green job skills on the shoreline. Our view of what matters continues to expand as connections that were once cloudy—between habitat restoration and environmental justice, between upland and bay habitats—come into focus. We’re not just trying to create small patches of tidal marsh but to piece together a huge mosaic of habitats from working lands to wetlands. We now know...

Saving a Species Struck by Systemic Oversights at Clear Lake

Since the 1950s, four native fish extinctions have taken place in Lake County’s Clear Lake: the thicktail chub, Clear Lake splittail, Pacific lamprey, and hardhead. A fifth endemic species, the Clear Lake hitch, is teetering on the brink. “Agencies view the hitch as just a fish. But for Tribes the hitch is sacred,” explains Big Valley Band of Pomo Indians tribal elder Ron Montez, Sr. “We believe Creator placed this fish here to help us survive for thousands of years. The chi (Pomo word for hitch) not only fed the seven Tribes around the lake, but it fed Tribes who came in from surrounding counties—Sonoma, Napa, Sacramento—and sustained all these people since time immemorial. That’s gone now. Anyone younger than...

An Inclusive Vision for Bouldin Island

Over resistance from local governments and environmental organizations, in 2016 Southern California’s Metropolitan Water District purchased five islands in the Sacramento-San Joaquin River Delta. While it wasn’t immediately clear what the powerful water agency intended for these islands, the move reminded some Californians of the “Wild West” years of water rights claimed by surreptitious land purchases. Now, years later, it appears the District is making good on that purchase by taking a leading role in Delta restoration efforts. The Delta Islands Adaptations project, funded through a watershed-restoration grant from the California Department of Fish and Wildlife, has zeroed in on Bouldin Island (the other four islands purchased at the same time were Webb Tract, Bacon Island, Holland Tract, and parts...

Boots on the Bayshore: Bay Trail

It’s largely taken for granted within the San Francisco Bay environmental community today that public trails through parks and preserves are both right and good: right, in the sense that they can offer equitable access to our region’s most treasured natural assets; and good, because they engender support for protection and restoration. But along the waterfront, trails weren’t always so welcome. “The local chapters of the Audubon Society and the Sierra Club were adamantly opposed,” recalls Tom Mikkelsen, who led implementation of the Bay Trail, an ambitious multi-use trail ringing the Bay, from its inception in 1988 until 2001. “Every time we came up with a project that was close to the edge of the Bay, they opposed it. And...

Sharing Science Across Barriers

Growing up on Chicago’s South Side, an urban landscape of metal and concrete, Miguel Mendez had limited access to open spaces, and always dreamed of traveling. Yet there in the city, he got his first introduction to environmentalism. “In some of the places I lived in Chicago, environmental activists are fighting air pollution and the limitation on parks,” Mendez says. Many of those groups have been there for years, and as he grew up, Mendez internalized the importance of preserving and advocating for a safe environment for all communities. When he was about to enter ninth grade, Mendez applied for a scholarship to an environmentally focused high school. So instead of walking into a classroom his freshman year, he found...

Science in Short: The Hullabaloo About HABS

Dead fish belly up in Lake Merritt and San Francisco Bay this past August sent scientists like Keith Bouma-Gregson scrambling to pinpoint the cause. A harmful bloom of marine algae had taken up residence in the Bay. Bouma-Gregson discusses his observations of the event in this podcast.

Key Facility’s Fuzzy Future

There are 14 marine laboratories in California. Just one of them is on San Francisco Bay: the Estuary and Ocean Science Center (EOS), on the rugged eastern shore of the Tiburon Peninsula in Marin County. EOS has trained generations of leading figures in estuary science and management. It possesses a site and facilities that no possible alternative could match. The research community swears by it. And in two years it might close. In the 1970s, after decades as a U.S. Navy property, the 53-acre parcel was considered for inclusion in the Golden Gate National Recreation Area. Instead, in 1977, it passed—for one dollar—to San Francisco State University (SFSU). But the bargain has devolved into a burden, and today a budget...

Defining Unimpaired Flows

For the second time in four years, a proposal for a voluntary agreement between agencies and water contractors on flows into and through the Delta from the San Joaquin and Sacramento rivers and their tributaries is wending its way through the State Water Resources Control Board. The proposal, which would replace the regime outlined in the Board’s most recent update to the Bay-Delta Plan, calls for substantially less water remaining in the system than the update, but comparing the two requires understanding some terminology, specifically the concept of “unimpaired flows.” In 2018 the State Board adopted Phase 1 of the Bay-Delta Plan update, calling for San Joaquin River inflows to the Delta of 40% of unimpaired flow; a framework for...

Building Buy-in for Restoration

The success of a restoration project is in the eye of the beholder. Take the recently revitalized salt marsh edging Drift Creek in Alsea Bay, Oregon. To ecologists, the sight of new channels winding through bare, brown mud is a thing of beauty, heralding the abundance of life to come, from sedges and rushes to fish and shorebirds. But, as researchers learned while speaking with people living nearby, not everyone shares this view. Some locals favored the unrestored side for its lush green vegetation and vistas of grazing elk. Resolving such differences in perception is key to local support, which can be required for project funding and permitting.  “Restoration can look unsightly at first,” said UC Davis salt marsh ecologist...

The Grande Dames of the Delta

The moveable bridges that cross the rivers and sloughs in the Sacramento-San Joaquin Delta were built in the first half of the 20th century, and most are operated by control panels as old as the bridges themselves. A day spent touring these strong-boned grande dames on backwater levee roads...

Listening to Vital Voices

Jessica Rudnick’s first love was earth science. But after discovering that people’s beliefs and behaviors were key to solving environmental problems, she fell for social science. Now, as the California Sea Grant extension specialist for the Delta, Rudnick is working to better integrate local people into plans for the region. Understanding the needs of people who live, work, and recreate in the Delta could make the difference between fixes that are rejected or embraced.  Delta planning has historically focused largely on ecological health. But, like many estuarine areas, the Delta is a lived-in landscape. “There are socially embedded challenges that play out in environmental issues,” she says. “You can’t just throw more data and research at a problem and think...

Bagman for Bay Mussels

Martin Trinh practically bounces along the dock at the Coyote Point Yacht Club on a breezy, sunny spring morning. He’s carrying a case full of instruments and scopes out an open slip at the end of the pier. Soon he’s lowering a probe into the water, alongside kelp clinging to the underside of the dock. Another trip back to his Prius, still sporting South Carolina license plates, and he’s got a white plastic dish pan and a scrub brush. He fills and rinses a brown plastic bottle several times before finally capping it while full and placing it into a zip-top plastic bag. Then he lies on his belly, reaches into the water, and with blue nitrile gloves feels amidst...

Asked to suggest an appropriate future for four Delta islands owned by the Metropolitan Water District, it’s difficult not to want the moon.

Why not richer rice fields, more wetlands, better boat launches, extended trails, even eco-tourism? ? A new survey for the Delta Islands Adaptation Project, funded by a Prop 1 Watershed Restoration Grant, wants the public’s opinion on the importance of 10 possible land-use objectives leading to the selection of one of the four islands for improvements. As your blinking cursor hovers over a satellite image of Bouldin, Bacon, Webb, and Holland Tracts, the survey lays out all that the experts know already: Holland is the least subsided; Bouldin the most accessible by road; Webb the best candidate for making more fish food, and more. “The Central Delta has some of the most critical landscapes in the state, and also some...

Science in Short: Daylighting Delta Data

Once you know how many fish are present in a particular part of a river, including additional details like the time of day and water temperature, what do you do with this information? For decades, Delta researchers have collected millions of similar data points from daily visits to the San Francisco Estuary, not all of which are available or immediately useful. How that information is then translated into a language relevant to water and conservation managers requires serious number, or data, crunching. Sam Bashevkin, senior environmental scientist at the Delta Science Program in the Delta Stewardship Council, is working to bring data science to the San Francisco Estuary and help to make sense of the overwhelming data troves generated by...

Eyeballing the Fish

Longfin smelt were what hooked Jim Ervin when he first learned about the UC Davis South Bay Fish Survey through a presentation at the 2012 Bay-Delta Science Conference. “They were catching them right there in our effluent channel!” recalls Ervin, a self-trained naturalist and former compliance manager for the San Jose-Santa Clara Regional Wastewater Facility. Intrigued, he contacted the researchers, rode with them on their next survey, and has been part of the project ever since, devoting more time to it after retiring from his wastewater facility job in 2018. “I have a free ticket to ride on the boat with fish experts who’ve been doing this for years,” he says. He began his Fish in the Bay blog in...

Gone Fishing

As the weekend dawns and California slumbers, the sportfishers descend, like clockwork, on the banks and waves of the San Francisco Bay and Sacramento-San Joaquin Delta. They carry nets for herring or poles for sturgeon, heavy and light tackle, bloodworms or anchovy or any number of delectable morsels to attract the desired target. They tread industrialized East Bay shorelines and marshy Delta banks, hop aboard sporty six-pack boats for more ambitious trips or humbler craft for a leisurely solo excursion. They catch (and often release) a smorgasbord of species: halibut, kingfish (white croaker), or sturgeon around the Bay, or striped bass, salmon, and black bass in the many tendrils of the Delta. “Here, you get both worlds, fresh and salt,”...

Better Living Through Fish – Editor’s Desk

I come from a long line of fisherfolk. My grandparents had a tiny cabin on a Quebec lake. We visited some summers. My grandfather let me drive the big white speedboat at a snail’s pace while he smoked cigars and trolled for trout off the stern. Once, when I caught one bigger than his catch-of-the-day, he “accidentally” knocked it back into the lake with the net. On the dock, we’d sunbathe while he cast lines overhead with a precision worthy of the movie A River Runs Through It. At the lake, we ate trout and eggs, trout salad, baked trout. I survived on spoonfuls of Cool Whip. (Photo above is editor as a teenager with Kay Rubbra, my grandmother, and...

DFW 150 Years on Patrol, and Work Still Dangerous

Lieutenant James Ober worked as a fish biologist with the California Department of Fish and Wildlife for a year before joining its Law Enforcement Division in 2009. “I enjoy interacting with hunters and fishers. Most of them have a great appreciation for the resources and want to protect them,” says Ober about being on patrol. Ober belongs to the tradition of wildlife officers, both personally and professionally. His fifth great grandfather, Edwin H. Ober, was an officer and biologist during the early 20th century, making James the second wildlife officer in his family. Ober is also one of the tens of thousands of officers who have worked to protect the natural resources of the San Francisco Bay since 1871. This...

Leading with Science: DWR’s Ted Sommer To Retire

A few months before his retirement in October 2021, Ariel Rubissow Okamoto asked Ted Sommer, lead scientist for the California Department of Water Resources, to reflect on his accomplishments and hopes for the future. Sommer is a leading researcher on native fishes, and has published more than 60 research articles in peer-reviewed scientific publications since 2001. Sommer began his long career at DWR in 1991 under Dr. Randy Brown. Early on he founded the Feather River fish monitoring program, but his work moved progressively downstream to the Bay-Delta, where he has also helped manage the Interagency Ecological Program since the late 1990s. According to his longtime colleague Jim Cloern, an emeritus scientist with the United States Geological Survey: “Ted has a...
