Estuary’s Question of the Month

A fall flight over the Mexican coast where the Colorado River meets the Sea of Cortez offered me a gut-punching, eye-screwing, visual on the results of impaired flow. The semantics of ‘unimpaired’ and ‘impaired’ flow have laced the language of California water management debates since some engineer invented these politically ‘neutral’ terms long ago. The terms refer to our alteration of freshwater flows from snowmelt and runoff by dams and diversions. But whatever the labels, or whichever estuary you’re referring...

Good Policy, More Tests for Living Shores

By Ariel Rubissow Okamoto While more sea walls may soon be necessary to adapt to rising seas, softer, greener, nature-based shorelines will also be important buffers for our cities and waterfronts. Wetlands, oyster reefs, eelgrass beds, and other natural features of shores and shallows figure largely in a number of ambitious, multi-partner restoration projects over the last decade. To date, more than 10 such projects have been or are being restored around the Bay, encompassing more than 200 acres of...

Speakers discuss forward-looking science in a rapidly changing environment, and the neuroscience of persuading people to care about climate change.

Climate Change Planning Mark Gold made the ultimate comment in his opening plenary at the State of the Estuary Conference: “The age of incrementalism, and not moving forward in a bold way, is not getting it done in terms of climate change.” Gold, deputy secretary for ocean and coastal policy for the California Natural Resources Agency, outlined the state’s newly revised strategic plan for a bluer economy, coastal resilience, and rapid response to fisheries emergencies. Following his talk, Geeta Persad...

Flows and Ecosystem Function Dominate Delta Plan Amendment

With the Delta lagging behind the Bay on four of the State of the Estuary Report’s five indicators, the last long-range plan for restoring its ecological health abandoned, and the threats from climate change becoming ever more alarming, the need for a new regulatory vision for the region may never have been greater. A pending amendment to the Delta Plan, shared by Ron Melcer at the State of the Estuary Conference as part of a policy update session, is meant...

Big Picture Review of Regional Science and Governance

Offshore, kelp forests were dwindling. Outside, hillsides were burning. Inside the Scottish Rite Center in Oakland, scientists and policy people were sharing the latest findings concerning the vital shallows in between: the San Francisco Estuary. The patient pursuit of knowledge, essential to smart action in a changing world, had chalked up a fruitful two years. Of the action itself, there was rather less sign. Felicia Marcus might speak to that better than anyone. As chair of the State Water Resources...

Speakers talk about emerging water quality issues such as stormwater management, contaminants in effluent, wastewater in Suisun Marsh, and nutrients discharged into the Bay.

Green Diet for Roads City of San Pablo project manager Amanda Booth went deep into the nitty gritty on green stormwater infrastructure at a State of the Estuary Conference session. “Talk to the utility agencies before you even start,” she said. “Read PG&E’s Greenbook guidelines. Know your city’s franchise agreements with gas, electrical, sewer, and water companies, figure out who pays to relocate facilities, for example, if that becomes necessary.” Changing the flow lines of runoff at the street, parcel...

Striving for Equitable Outcomes

By Audrey Mei Yi Brown Five people of color, four of whom who were women, took center stage in a full amphitheater for a 2019 State of the Estuary conference panel discussing how to achieve more equitable outcomes in both human and estuary health. Mishal Durrani, an undergraduate researcher at UC Berkeley, observed from the audience. “As a woman of color from an underrepresented community, it was powerful to see a panel with so many women of color represented.” As...

Speakers suggest communities could benefit from more green space, local knowledge, and engagement with homeless.

Green Matrix Erica Spotswood, an applied ecologist at the San Francisco Estuary Institute, has spent years studying biodiversity and its importance to ecosystems. “We have lost sight of something that is very simple but is not obvious to us now, which is that we need the same things biodiversity needs,” she said at the conference. She and other SFEI scientists are making the case for increasing biodiversity in cities, and have published a toolkit for how to do so in...

Not So Picky Marsh Mouse

The endangered salt marsh harvest mouse (informally “Salty”) is a poster child for tidal marsh restoration in San Francisco Bay. But recent research, presented by University of California at Davis postdoc Katie Smith in a State of the Estuary conference session on tidal wetlands, suggests we’ve misinterpreted what the mouse needs. “It’s been managed as a habitat specialist,” she said, based on assumptions that it requires tidal wetlands and a diet of pickleweed. However, hours of mouse-tracking around the Bay...

Speakers discuss issues facing Estuary wildlife and their wetland habitats, as well as drones and other new tools that will help future management.

Fish and Wildlife Check-up State of the Estuary Conference presentations featuring decades of data on fish, ducks, seabirds, and cetaceans revealed both hopeful and alarming trends. “The loss of federal funding for the midwinter waterfowl survey, usually conducted using small aircraft, has researchers looking at drone-based alternatives,” said waterfowl biologist Susan De La Cruz of the US Geological Survey. The overall community condition of the Estuary’s fish (abundance, distribution, diversity, proportion of native to non-native species) has declined, reported the...

View From the Precipice

By John Hart Scientific studies of the Bay and Delta tend to look intensely at small bits of the system. A countervailing theme at this State of the Estuary conference was the need to see wider, to “zoom out” — and most of all to help the public see the broad view, too.

About Us

The San Francisco Bay-Delta is named in the federal Clean Water Act as one of 28 “estuaries of national significance." For over 20 years, the San Francisco Estuary Partnership has worked together with local communities and federal and state agencies to improve the health of California’s most urbanized estuary.
