TL;DR
The U.S. Army Corps of Engineers Bay Model in Sausalito continues to operate as an educational exhibit, but it is no longer used for scientific research. Recent updates confirm its preservation and public accessibility.
The U.S. Army Corps of Engineers has confirmed that the Bay Model in Sausalito remains operational and open to the public, serving primarily as an educational exhibit rather than a scientific research tool.
The Bay Model, located at 2100 Bridgeway in Sausalito, California, was completed in 1957 and has since been a prominent hydraulic scale model of the San Francisco Bay and Sacramento-San Joaquin River Delta system. While it was originally used for scientific studies related to water flow and planning, it no longer supports research activities, according to Corps officials. Instead, it functions as an educational site, offering exhibits about Bay hydrology and water management.
Recent communications from the U.S. Army Corps of Engineers confirm that the facility remains operational and accessible to visitors. The model covers approximately 2 acres and features a detailed replica of the Bay and Delta, constructed from 286 concrete slabs. The model operates at a scale of 1:1000 horizontally and 1:100 vertically, with a time scale of 1:100, designed to simulate water flow and tidal effects. The site is a popular educational destination, attracting school groups and tourists interested in Bay ecology and engineering.
Why It Matters
This development is significant because it clarifies the status of a historic and educational resource that has played a key role in understanding Bay hydrology and water management. Its continued operation provides a tangible tool for public education and outreach, especially amid ongoing discussions about water resources and environmental impacts in California.

Background
The Bay Model was built in the late 1950s as part of efforts to evaluate large-scale dam and water diversion plans, such as the Reber Plan, which was ultimately abandoned after studies showed it was unviable. Over the decades, the model was expanded to include the Sacramento-San Joaquin Delta and has been used for various studies on navigation, water quality, and ecological impacts. Although scientific research has shifted away from physical models toward computer simulations, the Bay Model remains a valuable educational and historical asset.
“The Bay Model remains open and operational as an educational resource, with no current plans for closure or dismantling.”
