The Oakland Estuary is the strait in the San Francisco Bay Area, California, separating the cities of Oakland and Alameda and the Alameda Island from the East Bay mainland. On its western end, it connects to San Francisco Bay proper, while its eastern end connects to San Leandro Bay.

Crossings

The Estuary is spanned by two underwater tubes and three bridges. They are, from west to east:

Early history

Although the estuary was used by Native American tribes inhabiting the local area since about 4000 BC, the earliest recorded history of the Oakland Estuary dates primarily from events extending back to the 19th century, as detailed in a research study conducted by Earth Metrics for the U.S. Army Corps of Engineers (Earth Metrics, 1990)(Shreffler, 1994). The Oakland Estuary and tributary stream channels were used for shipping transport regularly by the 1850s; early maritime commerce featured movement of lumber and cattle hides. At this time land west of Lake Merritt Slough consisted of undeveloped marshlands. In 1853 the first dredging project of this estuary was initiated [1] , to enable ferry service to San Francisco. By the late 19th century further landside development occurred featuring wharf expansions, railroad service and shipbuilding. The estuary was dredged by the Army Corps of Engineers, making Alameda an island in 1913. Coast Guard island, originally known as Government Island, was formed in 1913 by the dredging project that extended the Oakland Estuary to San Leandro Bay.

Port of Oakland Container ship facility in Oakland, California

The Port of Oakland is a major container ship facility located in Oakland, California, in the San Francisco Bay. It was the first major port on the Pacific Coast of the United States to build terminals for container ships. It is now the fifth busiest container port in the United States, behind Long Beach, Los Angeles, Newark, and Savannah. Development of an intermodal container handling system in 2002 culminated over a decade of planning and construction to produce a high volume cargo facility that positions the Port of Oakland for further expansion of the West Coast freight market share.

East Bay Electric Lines

The East Bay Electric Lines were a unit of the Southern Pacific Railroad that operated electric interurban-type trains in the East Bay region of the San Francisco Bay Area. Beginning in 1862, the SP and its predecessors operated local steam-drawn ferry-train passenger service in the East Bay on an expanding system of lines, but in 1902 the Key System started a competing system of electric lines and ferries. The SP then drew up plans to expand and electrify its system of lines and this new service began in 1911. The trains served the cities of Berkeley, Albany, Emeryville, Oakland, Alameda, and San Leandro transporting commuters to and from the large Oakland Pier and SP Alameda Pier. A fleet of ferry boats ran between these piers and the docks of the Ferry Building on the San Francisco Embarcadero.

San Rafael Creek river in the United States of America

San Rafael Creek is a watercourse in Marin County, California, United States that discharges to San Rafael Bay, a small embayment of the San Francisco Bay. The mouth of San Rafael Creek is a channelized estuary through an industrial area. San Rafael Creek has a designation under Federal Law Section 303(d) as impaired by diazinon, the principal pollutant causing impairment designations for streams discharging to San Pablo Bay, which is the northern arm of San Francisco Bay. In September 2007, the organization Save The Bay designated San Rafael Creek as one of the top ten "worst trash hot spot" waterways flowing into the San Francisco Bay. The channel portion of San Rafael Creek below the Grand Street Bridge is dredged on a regular maintenance schedule to keep the shallow draft channel navigable. Dredge spoils are disposed of at a site near Alcatraz Island.
