 His plan, in the late 1940s, was to fill in parts of the San Francisco Bay.Under the plan, which was also known as the San Francisco Bay Project, the mouth of the Sacramento River (from Suisun Bay) would be channelized by dams and would feed two freshwater lakes within the bay, providing drinking water to the residents of the Bay Area.The barriers would support rail and highway traffic and would create two vast freshwater lakes, supplying irrigation water to farms.
