Bay Model Panorama
The 1.5 acre Bay Model

Imagine San Francisco without the bay. It almost happened. The Bay Model is a 1.5 acre, three-dimensional, working hydraulic model (yes! with water!) that helped scientists determine how proposed changes to San Francisco Bay would impact the environment and saved the Bay from destruction. Help us educate the public about the importance of the largest estuary on the West Coast and its impacts throughout California.

Volunteers are needed on an ongoing basis to provide visitor services by staffing the Bay Model Visitor Center reception desk, answering questions in person and over the phone, and conducting bookstore sales. We are also seeking docents to lead public tours of the model, including leading school groups, on topics from watershed ecology, tides and currents, history of the delta, hydrology of the bay and more! ***PLEASE NOTE: Due to COVID-19 all guided tours are currently suspended and we are only accepting new front desk volunteers. Stay safe!

Mission Statement

The U.S. Army Corps of Engineers provides design and engineering services and construction support for a variety of military and civilian projects world wide. One of the Army Corps' primary civil roles is to manage the nation's waterways and wetlands. The Army Corps activities include, but are not limited to, constructing projects approved by Congress for flood control, commercial navigation, or shipping channel maintenance; emergency response to natural disasters; operating and maintaining flood control reservoirs and public reclamation facilities; and regulating activities in wetlands including issuing dredge and fill permits and authorizing the establishment of wetland areas. The Army Corps is also the largest water based recreational agency in the U.S.


The Bay Model Visitor Center is a fully accessible education center administered by the U.S. Army Corps of Engineers which makes possible the viewing of a (retired) scientific tool: a working hydraulic model of the San Francisco Bay and Sacramento - San Joaquin River Delta System. The Model provides a unique opportunity to view the complete Bay-Delta system at a glance. Visitors are able to observe an average day's tidal pattern on the model in under 15 minutes!
