“As soon as it stops raining or snowing, we’re going to be back in the same situation with the salmon season closing,” said @jarosenfield.bsky.social, science director at San Francisco Baykeeper. “If we don’t protect river flows and cold water storage, then we’re not protecting salmon.”

Still can’t believe these epic skies over San Francisco during today’s thunderstorms 😍

In a major win for the South Bay, a federal judge has ruled that Mountain View & Sunnyvale violated the Clean Water Act by allowing raw sewage to flow into Stevens and Calabazas creeks--and that they must take steps to fix the problem: www.nbcbayarea.com/video/news/l... @nbcbayarea.com

The @noaa.gov data is in. March 2026 was 9.35 degrees Fahrenheit above the 20th century normal across the U.S., the warmest March in more than 130 years of records. California, Nevada, Idaho, Utah, Arizona, Wyoming, Colorado, New Mexico, Oklahoma and Texas were all record warm.

Gift article. Bay Area peeps, great news about Golden Gate Fields potentially becoming a 161-acre waterfront park. It's right next to the Albany Bulb and Mudflats. www.sfchronicle.com/bayarea/arti...

People are often surprised to find that sand mining is happening right here in SF Bay - with the blessing of the state, which has been selling millions of tons of sand to make concrete & asphalt. But sand isn't just sand, as our director Sejal Choksi-Chugh writes: baykeeper.org/column/the-b...

San Francisco is at 86°F at 1pm. On the way to shattering the March temperature record of 87°F (2005).

San Francisco Baykeeper is suing the State Lands Commission over a deal allowing the removal of 1.7 million cubic yards of sand each year from the bottom of the San Francisco Bay.

Most people don't know this but the state is selling SF Bay's dwindling sand so that for-profit companies can turn it into concrete. Bay sand provides habitat for countless creatures and literally shores up the shoreline. We *need* that sand. So we're suing: baykeeper.org/press_releas...

Condors are believed to be nesting on California’s North Coast — a major milestone in the Yurok Tribe’s effort to return the endangered raptors to their ancestral homeland. Europeans settlers poisoned and shot the birds into oblivion in the region a century ago. www.latimes.com/environment/...

In this debut episode of ONCE UPON A BAY, hosts Kate Josephs & SF Baykeeper founder Mike Herz share the story of how their lives—and their love—became entwined with San Francisco Bay 🌊 rss.com/podcasts/onc...

“Fish” can be both singular (one individual) and plural (multiple individuals of the same species.) “Fishes” is multiple species. 🐠 Fish 🐠🐠🐠 Fish 🐠🐡🐟 Fishes Now you know. And knowing is half the battle.

State officials have a once-in-a-generation chance to save California salmon—and they're failing. As our lead scientist @jarosenfield.bsky.social stresses in this article from @mavensnotebook.com, the state's plan would drive native fishes to extinction mavensnotebook.com/2026/02/12/n...

"The voluntary agreements are an extinction plan," as our lead scientist @jarosenfield.bsky.social describes the state's new Bay Delta Plan. Endangered species will continue to plummet, more fisheries will shutter, and Tribes & Delta communities will continue to suffer with worse water quality.

True, True

Environmental advocates say the proposal would take too much water out of the Delta, threatening fish from the finger-sized smelt to the giant white sturgeon. "What we are witnessing can only accurately be described as ecosystem collapse." www.latimes.com/environment/...

One of the biggest threats to California's coast & shorelines happens out of sight along the Bay's floor, where private companies mine sand for profit -- harming wildlife & eroding our beaches. Learn more and take action: baykeeper.org/take-action-... @surfrider.org
