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.
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 …

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.

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.

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.
