Bay Model, California

The Army Corps of Engineers, responsible for most of the dredging and filling projects around the Bay, maintains the Bay Model in one of the original Marinship warehouses. The model is a 1.5 acre functional scale model of the entire San Francisco Bay/Sacramento-San Joaquin River Delta system, built originally in 1957 to test bay fill projects (such as the Reber Plan), and is now used primarily as an educational display. It is the only remaining, intact, and functioning hydraulic model of this size in America, and it shows the whole of the Bay and Delta region, surrounded by displays and kiosks.
