Once Upon A Bay
Stories celebrating San Francisco Bay
Former Baykeeper Michael Herz loves San Francisco Bay and spent decades defending it from polluters. Kate Josephs learned to love it from 3,000 miles away, one story at a time. Now they're together on a boat in San Pablo Bay, collecting and sharing stories that celebrate one of most extraordinary bodies of water in the world.
From shipwrecks and whale migrations to hippies, drunkards, fish stories, courtroom battles, and secret CIA vessels, ONCE UPON A BAY dives into the natural and human history of San Francisco Bay, taking note of its fragility, its resilience, and all the people who care for it.

San Francisco Bay
ONCE UPON A BAY is a celebration of San Francisco Bay, the largest Pacific estuary in the Americas. It is stunningly beautiful, biologically diverse, and has supported people, plants, birds & fish for millennia. It is also under intense pressure from population growth, landfill, industrial activity, water diversion, and climate change. Join us to meet the people who care about the Bay. Meet the creatures who live in, around, and on it… and learn why the Bay matters so very much.
Join us in loving San Francisco Bay.
