The San Francisco Bay (Bay) drains water from 40 percent of California. This includes flows originating from the Sierra Nevada mountain range and the Sacramento and San Joaquin rivers that make their way down through Sacramento-San Joaquin Bay Delta through the Bay to the Pacific Ocean.
The Bay is the largest harbor on the U.S. Pacific Coast and covers about 400 square miles with an average depth of 14 feet. Its deepest point is 360 feet at the Golden Gate.
Every year, more than 67 million tons of cargo pass through the Golden Gate. The Bay also supports commercial bait shrimp, herring and Dungeness crab fisheries.
The Bay is a vital estuary and a key link in the Pacific Flyway, and millions of waterfowl use the shallow portions of the bay as a refuge each year.
Coastal communities should not rule out a sea-level rise in excess of 6.5 feet, according to the study published this week in the Proceedings of the National Academy of Sciences. … Should this worst-case scenario come to pass, good portions of cities like New York City and Miami on the East Coast and Los Angeles and San Francisco on the West Coast would be underwater by 2100.
While Belvedere officials consider a series of flood control projects that could cost up to $27.1 million, the city has appointed a new advisory committee that represents some of the hillside homeowners who say that money shouldn’t come out of their pockets. … An engineering consultant has designed several iterations of the projects, which are meant to safeguard the community from the forthcoming effects of sea-level rise.
The combination of droughts and floods has given rise to a process known as saltwater intrusion — what San Jose Mayor Sam Liccardo refers to as his city’s greatest climate threat. … In coastal regions like San Jose, overpumping allows seawater to seep into the city’s aquifers, exposing local residents to excess sodium in their drinking water. The problem is compounded by sea level rise, which pushes seawater inland toward the city’s filtration system.
According to a new study by Audubon California, the illegal mooring of private boats has caused significant harm to the eelgrass bed in that bay, with 25 to 41 percent of the seafloor habitat suffering damage. … The number of boats moored in Richardson Bay, known as “anchor-outs,” has increased from about 90 boats in the early 2000s to as many as 240 in 2016.
A data storage company wants to siphon water from the bay to cool its equipment, a process it says is greener and more sustainable than using traditional air cooling. But the idea is not winning over some environmentalists, because the water will warm slightly by the time it’s returned to the bay and they say that could potentially damage marine wildlife.
The commission, created in 1965 and comprised of 27 members appointed primarily by state and local officials, is supposed to protect the environmental health of the bay. If they won’t take their job seriously, Gov. Gavin Newsom, legislative leaders and local officials should replace them with people up to the task.
The Mountain View City Council approved the water district’s 18-foot-deep basin project in 2013 in exchange for the park upgrades. Designed to accommodate a 100-year flood, the McKelvey Park basin is one of two basin projects of the larger Permanente Creek Flood Protection Project, which water district officials claim will provide natural flood protection for approximately 2,200 properties in Mountain View and Los Altos.
Tens of thousands of people flooded into San Francisco in the 1850s looking for gold, but there wasn’t nearly enough drinking water to quench the thirst of the boomtown. So speculators looked south of the city to San Mateo County in hopes of delivering clean water to San Francisco and big money to their own pockets. And they weren’t going to let anything get in their way.
The San Francisco Bay Conservation and Development Commission has “neglected its mission” to protect the bay and surrounding wetlands, the California state auditor reported Tuesday. The commission, which issues permits for activities like boating, dredging and dumping, has a backlog of 230 open enforcement cases, some decades old.
On a former tidal marsh in Corte Madera that’s blanketed with bay mud and overgrown with invasive grasses, Golden Gate Bridge officials are planning a $2 million restoration project that would bolster habitat for an endangered bird species displaced by the Larkspur Ferry Terminal. The district has released the results of an environmental study of the proposed project and is accepting comments on the report until May 26.
The water that irrigates Santa Clara Valley’s last farms comes dirt cheap for growers who pump it out of the ground. They pay just a fraction — 6 percent — of the amount residents and businesses in the valley must pony up for their well water. The rest of the cost for farmers’ water is subsidized, mostly from revenue the Santa Clara Valley Water District receives through property taxes.
Once one of most extensive wetland areas in North America, the edges of the San Francisco Bay have become covered with farms, industry, and urban areas, squeezing out the marches and their animal and plant occupants. But at the lower end of the Napa River, a remarkable effort is underway to undo a century and half of damage to the once-thriving marshes.
For the third time in the last five years, Phillips 66 plans to pay to settle accusations that its Rodeo refinery released chlorine into San Pablo Bay. State water regulators announced Wednesday that the Houston-based company will pay $80,000 for violating chlorine limits in water it released into the bay more than a dozen times over a five-month period last year.
While oysters and sea grasses may not immediately stand out as defenders against sea level rise, a five-year test run using oyster reefs and eelgrass beds in the waters off of San Rafael has shown promising results. … Marshlands, reefs and other natural habitats have proven to buffer shorelines from erosion and powerful waves, but human development over the past two centuries has resulted in a substantial loss of these natural defenses.
If it doesn’t rain another drop for the rest of this “winter,” we got exactly 0.13 inches more than an ordinary season, putting 2018-19 at almost exactly the historical average.
There’s only one San Francisco Bay. But the Bay Area is made up of nine counties and 101 cities, each with its own politics, local rules and shorelines, differences that can make it complicated to figure out how to protect billions of dollars of highways, airports, sewage treatment plants, homes and offices from the rising seas, surging tides and extreme storms climate change is expected to bring in the years ahead. A new report released Thursday aims to make that gargantuan challenge a little easier.
The district is proposing to raise rates by about 4 percent annually over the next four years and to impose a new annual capital maintenance fee. The fee, which would be based on customers’ meter size, would switch the district from borrowing money to a cash-based system for funding repairs and replacement of pipes, pumps, water tanks and treatment plants.
Unusually high concentrations of carbon dioxide have been blowing out to sea from Bay Area cities and agricultural areas, raising concerns that the previously unknown infusions could increase ocean acidity faster than climate change experts have predicted, Monterey Bay scientists said this week.
By the 1930s, the Leslie Salt Company had consolidated over a dozen small producers into the world’s largest industrial salt production company, and half of the South Bay’s extensive marshes, whose ducks and salmon once far outnumbered humans, were gone. Now, the south San Francisco bay shoreline’s next mammoth transformation is well underway: a 50-year project to return the salt ponds back to the bay, restoring them once again into tidal marsh for the first time in 150 years.
In just the past week, water about an inch deep has popped up out of nowhere in both the northbound and the southbound lanes just south of the 880 interchange. … Underground aquifers are full from all the recent rain and pressure is now forcing water to bubble up in weak spots in the surface.
Every day, 46,000 people drive Highway 37, the scenic route that connects Marin County with Vallejo, Napa and just about everywhere east. This thread, though essential, is also tenuous in that it’s strung atop a berm barely above sea level. Traversing the vast salt marshes known as the San Pablo Baylands, the 21-mile stretch is emerging as an early challenge to planners confronting California’s changing climate.
Expected to temporarily hold excess sewer flows during storms, a project to build an underground flow equalization system underneath the San Mateo County Event Center parking lot is one of several components of San Mateo’s Clean Water Program. … But for many residents … pile driving and the installation of dewatering wells included in the project’s construction plans drew concerns about noise, the structural integrity of nearby homes and the project’s impact on neighbors’ quality of life.
Climate change is already negatively affecting the health of Marin residents and within 15 years attendant sea-level rise could threaten the county’s shoreline buildings, roads and original utility systems. This was the sobering message Marin supervisors received after Supervisor Kate Sears requested an update on the local health impacts of climate change and efforts to prepare for sea- level rise.
While this season has stood out in many people’s minds as noteworthy and painstakingly rainy, “it’s just a normal year,” said Jan Null, a consulting meteorologist with Golden Gate Weather Services. The city measured similar rainfall totals as recently as 2016-17.
Facing a wave of opposition over proposed fees for using well water, the directors of a little-known public agency backed away from a decision Thursday and agreed to consider an alternative plan that would exempt rural residents and cost other groundwater users far less overall.
As the Marin Municipal Water District gears up to consider another rate and fee hike this year, some of the public debate has turned to whether the district is paying too much in salaries and benefits to its employees.
San Jose Water, the local water company, recently sent out a public notice saying it wants to impose a year-long surcharge beginning this summer. The reason? To recover what it described as an “under-collection” of more than $9 million in fixed costs. … In other words, thank you for following the rules and limiting your water usage, but that’s hurt our bottom line, so we’ll be sending you a bill.
Our soggy spring has been a big boost to these so-called “vernal ponds,” ephemeral bodies of water which play a critical role in preservation of threatened and endangered creatures… The team found larvae of the threatened California tiger salamander in 28 of the 58 pools they monitor. The endangered vernal pool tadpole shrimp was found in 49 of these pools. That’s the third-highest tally in recent years.
Almost everyone who flies into San Francisco or San Jose airport has seen it — a vibrant patchwork quilt of colorful water. … As part of a huge effort called the South Bay Salt Pond Restoration Project, the Cargill salt company has freed almost 16,000 acres of their salt ponds.
A fierce battle by Berkeley firefighters to prevent a gas-tank explosion succeeded in averting a potential disaster this week — but an apparently deadly aftereffect is that hundreds of fish were killed when water and retardant foam from the firefight flowed into a nearby stream.
Too often considered a problem confined to the Central Valley and agricultural communities, the fact is that lack of access to safe, clean drinking water in school water fountains and home faucets affects every region of our state. This is a situation Gov. Gavin Newsom has rightly called a “disgrace” and has made it a priority to fix the crisis. In this life-saving endeavor, he has the support of Silicon Valley’s most innovative companies.
Five months after voters approved a bond measure to protect the waterfront from earthquakes and flooding from sea-level rise, San Francisco plans to start using the first batch of funds. Next week, The City is expected to introduce to the Board of Supervisors for approval a proposal to use $50 million of the $425 million Embarcadero Seawall Earthquake Safety general obligation bond approved by more than 80 percent of the voters in November.
Spearheaded by the San Mateo Resource Conservation District, with additional support from California State Parks and the National Oceanic and Atmospheric Administration, the project aims to re-establish more than a mile of the historic creek channel, remove 45,000 cubic yards of sediment and restore more than 10 miles of habitat for threatened steelhead trout and endangered coho salmon.
“The community is miserably divided,” said Napa County Supervisor Diane Dillon during a meeting on Tuesday. Dillon and her four fellow board members were tasked with crafting and approving the Water Quality and Tree Protection Ordinance, a controversial new law that seeks to conserve trees and forested areas while improving water quality for the many creeks that feed the Napa River.
This may be the bleakest shoreline in the Bay Area, and it isn’t just the industrial infrastructure that gives character to this place. Floating trash has collected along the docks, and the waters are contaminated by the loading and unloading of vast amounts of fossil fuels. A sign posted to a piling warns fishers not to eat anything they catch here.
Major new efforts to manage runoff and protect existing homes and businesses will be needed. Sea level rise will also affect water management in other ways. One area is wastewater treatment. Throughout coastal California and particularly in the San Francisco Bay Area, wastewater and stormwater treatment takes place in facilities that are currently at or near sea level. Water supply will also be affected. Many coastal aquifers will see increases in salinity …
In places like Oakland, flooding will occur not just at the shoreline, but inland in areas once considered safe from sea level rise, including the Oakland Coliseum and Jones Avenue, where [UC Berkeley professor Kristina] Hill and her students now stood, more than a mile from San Leandro Bay. In fact, she added, rising groundwater menaces nearly the entire band of low-lying land around San Francisco Bay, as well as many other coastal parts of the U.S.
The Santa Clara Valley Water District, Santa Clara County Board of Supervisors and Santa Clara Valley Open Space Authority all recognize the importance of curbing urban sprawl, encouraging farm-to-fork enterprises, and providing open space for urban dwellers through various policies. However, well-meaning changes may have unintended consequences, putting these goals in jeopardy.
U.S. Rep. Jackie Speier, D-San Mateo, and U.S. Sen. Dianne Feinstein, D-CA, called on EPA Administrator Andrew Wheeler to explain how the agency determined that the Redwood City salt plant site was not subject to federal permitting under the Clean Water Act despite an earlier draft that stated otherwise.
Milpitas mayor Rich Tran is following up on a campaign promise to do something about the bad odor that has drifted over the city for decades. … The goal is to trace the source of the stench, which residents have long suspected to come from the Newby Island landfill, the San Jose-Santa Clara Regional Wastewater Facility or the Zanker-owned recycling facility.
With rising tides threatening to submerge the Palo Alto Baylands by mid-century, city officials agreed on Monday they need to explore new barriers — both physical and legislative — to protect coastal area from sea level rise. These measures will be approved as part of a new Sea Level Rise Implementation Plan, a document that Public Works staff are in the process of putting together and that could have significant ramification for properties around the Baylands.
After years of planning, the Las Gallinas Valley Sanitary District is gearing up to break ground on a three-year, multimillion-dollar renovation of its sewage treatment plant. Workers were rained out the past couple of months but are now preparing the work site at the district headquarters at 300 Smith Ranch Road in San Rafael to replace the wastewater treatment facilities and expand its recycled water capacity.
A move by the Environmental Protection Agency could revive the contentious plan to develop 1,400 acres of Redwood City shoreline owned by Cargill Salt, which operates an industrial plant there. The EPA removed one barrier to development earlier this month by ruling that the area is not subject to restrictions in the federal Clean Water Act. That puts the EPA at loggerheads with environmentalists, who want to convert the land back to tidal wetlands.
By allocating $1 million last week toward a creek restoration project set to rejuvenate threatened and endangered species and reduce flooding in Pescadero, county officials locked in funding needed to begin a dredging effort experts expect will give the Butano Creek a chance to reset.
A sprawling stretch of salt ponds on the western edge of San Francisco Bay, once eyed for the creation of a virtual mini-city, is back at the center of debate over regional development after the Trump administration this month exempted the site from the Clean Water Act.
One way or another, $53 million of Utahns’ money soon may get sunk into a deep-water export terminal on the West Coast in an effort to shore up the state’s fading coal industry. On Monday, a Senate panel advanced a bill that would transfer a special fund to the Utah Office of Energy Development… That fund was set up to legitimize a $53 million CIB loan that four coal-producing counties hoped to invest in a controversial export terminal under development in Oakland, Calif.
A long battle over development of the Cargill salt ponds in Redwood City may soon return after the EPA declared the site exempt from the federal Clean Water Act — causing concern by environmentalists and the city’s mayor. The Environmental Protection Agency announced its decision earlier this month, effectively removing one of several barriers to development of the 1,400-acre Bayside property.
Gov. Gavin Newsom should immediately allow the thinning of vegetation on almost 94,000 acres of state land in a bid to keep more than 200 communities safe, California fire officials said Tuesday as they released a list of the state’s 35 most critical fuel-reduction projects.
In 70 years, San Francisco as we know it could look drastically different. Gentrification, development and the other forces of urban change we fret about may be mere trifles compared to the drastic effects of climate change, including the rise of sea levels and erosion, scientists say. By 2100, rising sea levels could displace more than 480,000 people along the California coast and result in property losses upwards of $100 billion if no preventative measures are taken, according to a 2009 study by the California Climate Change Center.
For decades, the steelhead trout and Chinook salmon trying to complete their instinct-driven trip upstream have been blocked by an impassable concrete structure known as the BART weir, which supports the trains overhead. Within a few years, however, this capturing and relocation may not be necessary as the Alameda County Water District, in conjunction with other public agencies, is investing nearly $70 million in upgrading or replacing rubber dams and building fish ladders.
A countywide effort to address sea level rise is gaining momentum after San Mateo County supervisors took steps to form a new government agency to manage flooding, sea level rise, coastal erosion and stormwater infrastructure this week. By expanding the San Mateo County Flood Control District’s responsibilities … officials have looked to facilitate coordination between jurisdictions as they set their sights on a new set of challenges for water infrastructure projects.
A new approach to flood management around the San Francisco Bay could trim maintenance costs for water agencies, restore habitat for endangered species, and help protect against rising seas. What links the three? Sediment. Winter storms push sediment down creeks that flow into the Bay and, long ago, these waterways fanned out when they reached the edge. Sediment settled there, nourishing tidal baylands — salt marshes and mudflats that are rich in wildlife, and also buffer the shore from storm surges, the highest tides, and sea level rise. Today few of these low-lying tidal baylands remain.
What was supposed to be a great flood control project that kept homes safe in the South Bay has turned into a nightmare for many homeowners. Repair crews continue to work on Ridgemont Drive in San Jose, where they are replacing brick pillars residents claim were damaged by the pounding to the flood control project along the Silver Creek. Homeowners are footing the bill for the repairs and say someone else should be paying.
The rainwater collection system is broken at the environmental research station on a remote, rocky Pacific island off the California coast. So is a crane used to hoist small boats in and out of the water. A two-year supply of diesel fuel for the power generators is almost gone. U.S. Fish and Wildlife Service personnel ordinarily would help with such problems. But they haven’t been around since the partial federal government shutdown began a month ago…
Doing surgery on San Francisco’s water system is no simple task. Replacing one mile of distribution main costs about $3.8 million dollars. That’s just the direct cost of installing a section of drinking water pipe. There are also side effects: disruptions to traffic, sidewalks, and businesses when streets are pried open. In one of the nation’s densest and highest-cost cities the expense amounts to an incentive for well-informed decisions about what to dig up and when.
In the North Bay, so much runoff from our recent rains has created some spectacular sights. Waterfalls are becoming big attractions around Mt. Tamalpais. The sound of rushing water is everywhere in the lush, emerald green hills below Mt. Tam.
The Alameda County Water District is proposing to raise customers’ bills 8 percent over the next two years to cover infrastructure costs as well as salary increases, benefits and pensions for its employees. The district also wants to create an emergency pricing schedule that kicks in during water shortages, such as in droughts.
Top managers of the environmental engineering firm Tetra Tech directed their employees to commit widespread fraud in the cleanup of America’s largest Superfund waste site, according to new legal complaints by the U.S. Department of Justice.
Montgomery is known for fostering collaborative relationships among stakeholders and as a leader in protecting and restoring water quality within California and throughout the Southwest and the Pacific Islands. He is currently serving as the Assistant Director of the Water Division in the US Environmental Protection Agency (Region 9).
A state board on Wednesday approved a contentious proposal to boost water flows through a Central California river, a move that would increase habitat for salmon but deliver less water to farmers and cities such as San Francisco. The plan under consideration by the Water Resources Control Board would alter management of the Lower San Joaquin River and three tributaries to address what environmental groups say is a crisis in the delta that empties into San Francisco Bay.
Del Mar is a picturesque place that’s name means “of the sea,” in Spanish. That’s becoming increasingly true. Del Mar is one of countless coastal communities in California and across the U.S. that is seeing the impacts of climate change and preparing for worse to come.
The biggest ticket item on California’s November ballot, tucked between the governor’s race and local elections, is an $8.9 billion bond to help modernize California’s sprawling waterworks. The measure, which was authored by a former state water director, would fund scores of projects, from shiny new desalination plants to upgrades of old dams and aqueducts to restoration of tainted watersheds, including San Francisco Bay.
Pacific Gas and Electric Co. has agreed to protect San Francisco and Humboldt bays from runoff of dangerous chemicals on utility poles in a settlement with an environmental group. … The suit said oil and wood waste from poles stored at the yards washed into the bays, damaging the environment and endangering human health and wildlife.
Wading into the water along the rocky shore off Aramburu Island in Richardson Bay, Brian Cheng reached 3 feet under water and pulled up an algae-covered rock. “Here we go,” he yelled as he splashed ashore soaking wet and pointed out a tiny snail on the underside of the rock. “And, we got a bonus,” he said, gesturing toward a cluster of yellow gelatinous egg capsules.
Following nine years of research, a California agency has proposed to increase water flows in the San Francisco Bay-Delta Estuary. But the decision is causing contention between farmers and fisheries. … The California Water Board is scheduled to vote on the proposal in August.
The amazing thing about the 35 people who swam for miles in the San Francisco Bay on Sunday — besides that they swam for miles in the San Francisco Bay — is that they came out of the water soiled only by saltwater. Maybe some seaweed. No sewage clung to their hair.
A final draft plan for the San Joaquin River system has been released by state water regulators. … But Friday the State Water Board also released a “framework” for a similar plan being prepared for the Sacramento River watershed, which would see even larger reductions of diversions in the north valley.
California water officials on Friday released a plan to increase flows through a major central California river, an effort that would save salmon and other fish but deliver less water to farmers in the state’s agricultural heartland.
State regulators proposed sweeping changes in the allocation of California’s water Friday, leaving more water in Northern California’s major rivers to help ailing fish populations — and giving less to farming and human consumption.
This small rectangle of wetland near the San Francisco Bay in San Lorenzo doesn’t look particularly visionary. Above ground, it’s an appealing – if unusually orderly – array of meadows, cattails and willows. But there’s far more here than meets the eye. This modest strip of land, just 38 by 150 feet, in the Oro Loma Sanitary District promises to help solve two of the Bay Area’s most pressing concerns: sea-level rise and nutrient pollution.
Proposition 68 was approved with 56 percent of the vote to authorize the state to borrow $4.1 billion for investments in outdoor recreation, land conservation and water projects, according to the latest results Wednesday morning.
In October 2002, the cruise ship Crystal Harmony anchored outside Monterey Harbor, ferrying more than 900 passengers ashore for the day before continuing on its way to Acapulco, Mexico. Later that night, 14 miles off the pristine coastline of Big Sur, the 790-foot-long ship dumped 36,400 gallons of sewage, gray water and oily waste into the Monterey Bay National Marine Sanctuary.
You can shove water back from the land, or let the land flood, but either way, San Francisco Bay is getting higher. Along more than 400 miles of bayfront, in at least forty communities that touch water, the once-sneaky problem of sea level rise is revealing itself as it accelerates.
Design teams from around the world unveil their visions today for a ring of ambitious projects circling San Francisco Bay, all aimed at increasing “resilience” to the challenges of rising sea levels and other growing threats to communities. After a year’s worth of ground work, nine teams participating in the Resilient by Design Bay Area Challenge take the wraps off of their various visions.
The city of Oakland and East Bay Municipal Utility District must pay more than $360,000 for violating the Clean Water Act by allowing untreated sewage into the San Francisco Bay, officials said Tuesday. In 2014, EBMUD and seven East Bay communities it serves, including Oakland and Berkeley, paid $1.5 million in civil penalties for past sewage discharges.
A local environmental watchdog group says it has reached a legal settlement with operators of the Newby Island Resource Recovery Park landfill to curb toxic runoff into local waterways.
Back in June 2016, Bay Area voters approved Measure AA to raise $500 million to pay for wetlands restoration, flood control and wildlife projects around San Francisco Bay. Now the first wave of that money — nearly $18 million — is about to be put to use. On Wednesday, the board overseeing the money will vote on projects in six counties totaling $17.9 million.
A $1.3 trillion spending package approved Thursday by the House and early Friday by the Senate includes nearly $448 million for Environmental Protection Agency programs benefiting regional waters degraded by pollution, overdevelopment and exotic species invasions. … Aside from the Great Lakes, those staying at their current levels include Chesapeake Bay, San Francisco Bay …
A whopping 99 percent of mussels collected from the San Francisco Bay were contaminated with at least one algal toxin, while more than a third contained four different kinds of algal toxins, according to a study published in the March issue of the scientific journal, Harmful Algae.
It [proposed 2019 budget] would remove all EPA funding of cleanup programs for the Gulf of Mexico, Lake Champlain, Long Island Sound, San Francisco Bay, Puget Sound and South Florida, including the Everglades and Keys.
San Rafael’s Canal neighborhood has been selected as one of 10 Bay Area sites to get attention from a phalanx of architects, urban planners and environmentalists as part of a competition to battle sea-level rise. Fueled by an almost $5 million grant from the Rockefeller Foundation, teams have been formed to tackle what researchers say is inevitable flooding brought on by climate change.
Last winter’s drought-busting wet weather was a boon for reservoirs and parched landscapes, but not so much for some invasive species in San Francisco Bay, according to a long-term study by Tiburon-based researchers. All that fresh water that poured into the bay was bad news for certain invaders, which have turned up in droves in recent decades from around the world, often in ships’ ballast water.
Next time you spray Rover or Fluffy for fleas, you may be harming San Francisco Bay. An insecticide found in commonly used over-the-counter flea treatments like Frontline Plus and Pet Armor appears to be washing down pet owners’ drains and flowing through sewage treatment plants into the bay, new research shows.
Nutrients – such as nitrogen – are essential to life, but an overabundance can mean trouble for waterways. Take Chesapeake Bay and the Gulf of Mexico, which are infamous for “dead zones” where closely packed bodies of fish float to the surface or wash ashore by the thousands. These dead zones are caused by nutrient pollution, which makes algae grow too fast.
Estuaries are places where fresh and salt water mix, usually at the point where a river enters the ocean. They are the meeting point between riverine environments and the sea, with a combination of tides, waves, salinity, fresh water flow and sediment. The constant churning means there are elevated levels of nutrients, making estuaries highly productive natural habitats.
Last year, on June 7, the nine counties of the Bay Area passed a ballot measure called Measure AA. The measure placed a $12 per year parcel tax on local landowners to be directed towards wetlands restoration.
Despite spending millions of dollars over the years on garbage cleanup, Oakland has the Bay Area’s worst record for limiting the rubbish that pollutes creeks, lakes and the bay, according to the San Francisco Bay Regional Water Quality Control Board. The flow of waste violates mandates set by the board to reduce storm drain litter this year by 70 percent compared with 2009, a goal that Oakland is far from meeting.
Three days after the 112-foot barge Vengeance overturned in high winds near Yerba Buena Island, the U.S. Coast Guard worked Sunday to contain the diesel slick spilled from its depths and walked nearby beaches to check on wildlife.
There were no new signs of fuel leaking into San Francisco Bay as a Coast Guard helicopter crew carried out an overflight and divers conducted an underwater assessment Saturday on a freight barge that sank south of the Bay Bridge.
The Trump administration could eliminate all federal funding for wetlands restoration in San Francisco Bay, according to a budget plan that has shocked local and state officials, but is just one piece of broad changes to federal environmental programs.
The heavy storms that washed away California’s drought this season have come with a side effect: large slugs of pollution and sewage washing into San Francisco Bay and the Delta.
San Francisco voters will be asked to allow $350 million to be spent on a first round of improvements for the city’s crucial but fragile Embarcadero seawall, officials said Monday.
Powerful storms often hailed for bringing drought-busting rains to California also served to virtually wipe out a healthy growth of native Olympia oysters at China Camp near San Rafael, raising concerns about climate change, according to a new study.
Understanding the importance of the Bay-Delta ecosystem and working to restore it means grasping the scope of what it once was.
That’s the takeaway message of a report released Nov. 14 by the San Francisco Estuary Institute.
The report, “A Delta Renewed,” is the latest in a series sponsored by the California Department of Fish and Wildlife (DFW). Written by several authors, the report says there is “cause for hope” to achieving large-scale Delta restoration in a way that supports people, farms and the environment. SFEI calls itself “one of California’s premier aquatic and ecosystem science institutes.”
The San Francisco Bay Joint Venture — celebrating its 20th anniversary this year — has helped coordinate and complete more than 150 wetland habitat projects, conserving and restoring about 75,000 acres of habitat in and around the bay since 1996.
High levels of a toxic freshwater algae known to be harmful to humans have been detected in mussels at several locations in San Francisco Bay, scientists said Monday.
The Bay Area made history in June 2016 by passing Measure AA, a wetland restoration parcel tax and the first ballot measure to include all nine counties. Besides providing wildlife habitat and flood protection, the measure may hold lessons for future regional governance. Most of all, however, the measure’s success underscores how important the Bay is to us.
Evidence of what scientists are calling the planet’s Sixth Mass Extinction is appearing in San Francisco Bay and its estuary, the largest on the Pacific Coast of North and South America, according to a major new study.
Unlike most other microorganisms, zooplankton are technically heterotrophic animals – meaning they cannot produce their own food. Instead, they feed upon phytoplankton like algae, a process responsible for keeping these populations under control.
Those small, seemingly insignificant bits of plastic in San Francisco Bay found at nine local sites last year could end up being the next major water quality problem. What to do about them is an important next step, said Rebecca Sutton, senior scientist with the San Francisco Estuary Institute (SFEI). During a Thursday seminar sponsored by the State Water Resources Control Board in Sacramento, Sutton said experts are embarking on a course of better understanding microplastic contamination and its effect on the environment and human health.
Today [July 1], the U.S. Environmental Protection Agency proposed a federal Clean Water Act rule to tighten the current selenium water quality criteria for the waters of San Francisco Bay and Delta. The proposed change would better protect aquatic species, including salmon, smelt, and diving ducks, that are dependent on the Bay and Delta ecosystem, from harmful exposure to elevated levels of selenium.
Settling a major lawsuit from environmentalists, San Jose city officials on Tuesday agreed to spend more than $100 million over the next decade and beyond to reduce tons of trash that flows into creeks and San Francisco Bay, repair miles of leaking underground sewage pipes and clean stormwater contaminated with harmful bacteria.
Thousands of acres of land around the San Francisco Bay will be returned to wetlands after voters in the nine-county Bay Area approved a new $12-per-parcel tax that will raise millions of dollars for bay enhancement and habitat restoration.
The Bay Area’s first-ever nine-county ballot measure — a 20-year parcel tax intended to raise $500 million for marsh restoration and improved public access along the bay’s shoreline — was leading comfortably early Wednesday, with its strongest support from the most populous counties.
Fifty years ago, Bay Area residents rallied around the call to save San Francisco Bay. Public action on an unprecedented scale reversed development tides that for more than a century had covered shallow waters with land for industrial parks and housing tracts, roadways and garbage dumps.
Eleven years ago, it was a major threat to San Francisco Bay. A fast-growing, non-native plant that spread in dense thickets up to 7 feet tall was exploding out of control, overrunning wetlands, threatening birds, wildlife and even the public’s view of the water.
A 59-year-old South Bay man was charged with illegally dumping fill material, construction debris and other pollutants into the waters of the Don Edwards San Francisco Bay National Wildlife Refuge, officials said.
The long-term threat of a rising bay has prodded nearly a dozen city agencies to come together and respond with an action plan — “action” being a relative term.
Looking out at San Francisco Bay, you’d never know it’s dotted with tiny pieces of plastic. … This microplastic threatens fish and may also threaten people who eat them. “We can’t recover it once it’s into our watersheds and oceans,” said Stiv Wilson, campaign director at The Story of Stuff, a nonprofit in Berkeley.
In a clear sign that the largest wetlands restoration project on the West Coast is already improving the health of San Francisco Bay, bird populations have doubled over the past 13 years on thousands acres of former industrial salt-evaporation ponds that ring the bay’s southern shoreline, scientists reported Thursday.
San Francisco Bay is in a race against time, with billions of dollars of highways, airports, homes and office buildings at risk from rising seas, surging tides and extreme storms driven by climate change. … That’s the conclusion of a new report from more than 100 Bay Area scientists and 17 government agencies that may help fuel a regional tax measure aimed at addressing the looming crisis.
San Francisco Bay is contaminated with widespread pollution from billions of tiny pieces of plastic in greater concentrations than the Great Lakes, Chesapeake Bay and other major U.S. bodies of water, according to a groundbreaking new study.
A large cement factory near Cupertino will have to pay more than $7 million in fines and remediation for polluting a local creek that pours into San Francisco Bay, state and federal regulators said Wednesday.
California lawmakers led by Rep. Jackie Speier, D-Hillsborough, and Democratic Sens. Dianne Feinstein and Barbara Boxer introduced legislation last week to double the amount of federal grants to restore the bay, the largest estuary on the West Coast, to $10 million a year.
Estuaries are hard places to understand and even harder to explain. Estuarine scientists, myself included, have struggled to learn how changes in the San Francisco Estuary led to declining fish populations and waning productivity, particularly in the Sacramento-San Joaquin Delta.
Scientists have set up eating stations full of fish roe in the middle of Richardson Bay in an attempt to feed ducks whose numbers have been on the decline in recent years.
In a move that could force the city of San Jose to spend millions modernizing its sewage system, cleaning up trash and removing homeless encampments, an environmental group announced Monday it will file a lawsuit under the Clean Water Act charging the city with failing to stop pollution from washing into creeks and San Francisco Bay.
This 3-day, 2-night tour, which we do every year, takes participants to the heart of California water policy – the Sacramento-San Joaquin Delta and San Francisco Bay.
This 25-minute documentary-style DVD, developed in partnership with the California Department of Water Resources, provides an excellent overview of climate change and how it is already affecting California. The DVD also explains what scientists anticipate in the future related to sea level rise and precipitation/runoff changes and explores the efforts that are underway to plan and adapt to climate.
15-minute DVD that graphically portrays the potential disaster should a major earthquake hit the Sacramento-San Joaquin Delta. “Delta Warning” depicts what would happen in the event of an earthquake registering 6.5 on the Richter scale: 30 levee breaks, 16 flooded islands and a 300 billion gallon intrusion of salt water from the Bay – the “big gulp” – which would shut down the State Water Project and Central Valley Project pumping plants.
A 30-minute version of the 2005 PBS documentary Water on the Edge. This video is ideal for showing at community forums and speaking engagements to help the public understand the complex issues surrounding the New River.
Water truly has shaped California into the great state it is today. And if it is water that made California great, it’s the fight over – and with – water that also makes it so critically important. In efforts to remap California’s circulatory system, there have been some critical events that had a profound impact on California’s water history. These turning points not only forced a re-evaluation of water, but continue to impact the lives of every Californian. This 2005 PBS documentary offers a historical and current look at the major water issues that shaped the state we know today. Includes a 12-page viewer’s guide with background information, historic timeline and a teacher’s lesson.

This beautifully illustrated 24×36 inch poster, suitable for framing and display in any office or classroom, focuses on the theme of Delta sustainability.
The text, photos and graphics explain issues related to land subsidence, levees and flooding, urbanization and fish and wildlife protection. An inset map illustrates the tidal action that increases the salinity of the Delta’s waterways. Development of the map was funded by a grant from the California Bay-Delta Authority.
Water as a renewable resource is depicted in this 18×24 inch poster. Water is renewed again and again by the natural hydrologic cycle where water evaporates, transpires from plants, rises to form clouds, and returns to the earth as precipitation. Excellent for elementary school classroom use.
This 24×36 inch poster, suitable for framing, explains how non-native invasive animals can alter the natural ecosystem, leading to the demise of native animals. “Unwelcome Visitors” features photos and information on four such species – including the zerbra mussel – and explains the environmental and economic threats posed by these species.
This 24×36 inch poster, suitable for framing, explains how non-native invasive plants can alter the natural ecosystem, leading to the demise of native plants and animals. “Space Invaders” features photos and information on six non-native plants that have caused widespread problems in the Bay-Delta Estuary and elsewhere.
The 24-page Layperson’s Guide to the Delta explores the competing uses and demands on California’s Sacramento-San Joaquin Delta. Included in the guide are sections on the history of the Delta, its role in the state’s water system, and its many complex and competing issues with sections on water quality, levees, salinity and agricultural drainage, and water distribution.
A new look for our most popular product! And it’s the perfect gift for the water wonk in your life.
Our 24×36 inch California Water Map is widely known for being the definitive poster that shows the integral role water plays in the state. On this updated version, it is easier to see California’s natural waterways and man-made reservoirs and aqueducts – including federally, state and locally funded projects – the wild and scenic rivers system, and natural lakes. The map features beautiful photos of California’s natural environment, rivers, water projects, wildlife, and urban and agricultural uses and the text focuses on key issues: water supply, water use, water projects, the Delta, wild and scenic rivers and the Colorado River.
“State officials unveiled a longer-term plan to deal with the drought Wednesday, one which relaxes some water-quality standards and endangered species protections in the Delta to allow for more water to be sent south to parched cities and farms.”
Operated by the U.S. Army Corps of the Engineers, the San Francisco Bay/Delta Model is a hydraulic model of San Francisco Bay and the Delta and is housed in a converted World II-era warehouse in Sausalito in Marin County.
Stretching 320-feet by 400-feet wide, the Bay Model features a replica of the Bay Delta watershed from the Golden Gate to the Sacramento-San Joaquin Delta. Pumping systems move hundreds of gallons of water throughout the display and create 14-minute tidal ebb and flow.
Invasive species, also known as exotics, are plants, animals, insects, and aquatic species introduced into non-native habitats.
Often, invasive species travel to non-native areas by ship, either in ballast water released into harbors or attached to the sides of boats. From there, introduced species can then spread and significantly alter ecosystems and the natural food chain as they go. Another example of non-native species introduction is the dumping of aquarium fish into waterways.
Without natural predators or threats, these introduced species then multiply.
This issue of Western Water looks at the BDCP and the Coalition to Support Delta Projects, issues that are aimed at improving the health and safety of the Delta while solidifying California’s long-term water supply reliability.
