Maps of San Francisco

San Francisco’s Underground Water and Creeks

The Oakland Museum publishes maps of underground water and watersheds in the Bay Area, including this one of San Francisco. But the publishers, Janet Sowers and Christopher Richard, have recently found historical evidence that indicates that the so-called Laguna Dolores did not exist. They’ve issued a new map without the lake, which is available from the Oakland Museum.
