Our Estuary

Explore Our Estuary

Our Estuary, the largest in western North America, encompasses San Francisco Bay and the Delta of the Sacramento and San Joaquin rivers in California. Unlike most estuaries that spread out into a wide delta of braided channels where rivers meet the sea, the San Francisco Estuary’s Delta is more than 60 miles inland, trapped behind coastal ridges after rising seas flooded the Bay 10,000 years ago. Managers often divide this complex water body into the Bay and Delta, or the upper and lower Estuary. It is all one system, however, connected by freshwater outflow to the pacific and by the ebb and flow of ocean tides far upstream into the Delta.

Indigenous People’s Acknowledgement 

Much of the work that the San Francisco Estuary Partnership and our environmental partners do is along the margins of the shoreline, with the understanding of its critical importance to the health and future sustainability of our Estuary. Long before development, fill, population growth, and rising seas forced renewed attention on this area however, the Estuary’s shoreline, baylands, and uplands were–and still are–vital to the health and sustainability of Indigenous people.

We honor and acknowledge the many Ohlone tribal groups and families including the Ramaytush and Chochenyo, as well as the Coast and Bay Miwok, Southern Pomo, Wappo, and Patwin peoples as the rightful stewards of the lands on which we reside.  Our work to protect and restore the margins of the Bay should acknowledge and be informed by the history of injustices, by the fact that we are working on the land of Indigenous people who were forced to relocate, and by the fact that our work is often adjacent to or even on top of sacred cultural sites. Recognizing the intersections between wetland restoration, shoreline recreation, and historical sacred sites can facilitate opportunities throughout our Estuary to restore, create, and protect for multiple purposes. We do this work in good faith, knowing it is centrally important that we work toward repair, reconciliation and reparations wherever possible.

Prior to colonization, Central California had the densest Indian population anywhere north of Mexico. Over 10,000 people lived in the coastal area between Point Sur and the San Francisco Bay, belonging to about 58 distinct tribal communities. There are several different Ohlone groups, whose homelands extended from north of the Carquinez Strait south to Monterey.  The San Francisco Bay Area shoreline was once the site of over 425 shellmounds (Ohlone sacred burial sites), village sites and ceremonial sites. Today, none of the Ohlone tribal groups have federal recognition, which (among other challenges) hinders their ability to protect their sacred sites.

We are working to build our capacity to be better stewards and allies to original peoples and disenfranchised communities across the Estuary. SFEP is engaged in training through the Government Alliance on Race and Equity, and we invite Indigenous people from anywhere in the Estuary to reach out to us to collaborate and identify opportunities for partnership.

Below is a list of resources to better inform and engage on these issues: 

Oakland Museum of CA Gallery of California History

This permanent gallery includes an exhibit on “Taking Native Lands and Lives” which covers the genocide of Native peoples in the early era of California’s statehood and the impact on California today. Link for more resources: https://museumca.org/history

Ohlone Curriculum with Bay Miwok Content

A helpful resource developed by Dr. Beverly Ortiz with the East Bay Regional Parks District. The curriculum is intended as part of the common core for 3rd Grade, and is also a helpful resource for anyone interested.
