# Port of Stockton

The Port of Stockton is a major deepwater port on the Stockton Ship Channel of the Pacific Ocean and an inland port located more than seventy nautical miles from the ocean, in Stockton, California on the Stockton Channel and San Joaquin River-Stockton Deepwater Shipping Channel (before it joins the Sacramento River to empty into Suisun Bay). By land acreage, the Port of Stockton is the 2nd largest port in the State of California and sits on about 4,200 acres (17 km$^2$), and occupies an island in the Sacramento–San Joaquin River Delta, and a portion of a neighborhood known as Boggs Tract. It is governed by a commission appointed by the City of Stockton and San Joaquin County. The Port of Stockton is a self-sustaining economic powerhouse in the Central Valley and in 2023, contributed over $78 million in state and local tax funds.

## Geography

The only natural outlet for the waters of the Central Valley to pass into the sea is through the narrow Carquinez Strait, at the inland eastern extreme of San Pablo Bay. Further inland are the Suisun and Grizzly Bays, arms of the Pacific Ocean deep in the Californian interior. Further inland again from these last bays is the broad Sacramento–San Joaquin River Delta, formed where the San Joaquin and Sacramento Rivers meet and cross together. This verdant triangle of land with deep black soils is at the heart of the Central Valley and stretches some fifty miles from Suisun Bay on the west to the cities of Stockton and Sacramento on the east. The Port of Stockton is the 2nd largest port in the State of California with 4,200 acres.

## Pollution

As a center of transport and commerce in a densely populated city, the Port of Stockton is conscientious about Port-related emissions that may impact local air quality and climate change. In 2022, the Port successfully undertook several efforts to reduce emissions and enhance planning efforts to transition to a cleaner, greener future - while ensuring cargo moves efficiently. The Port of Stockton has launched an ambitious effort to one day eliminate Port-related emissions entirely, and in the meantime, to significantly reduce impacts on our neighbors. Efforts include a Clean Air Plan, a Medium- and Heavy-Duty Vehicle Electrification Blueprint, and Truck Access Analysis.

## History

In 1846, the first cargo boat ascended the San Joaquin River. In 1848, John Doak established the first ferry service on the river, and the first freight vessel, the sloop Maria, visited Stockton. In 1849, Doak brought lumber from San Francisco to Stockton and began a lumber business. By the 1850s, the port had become a center of commodity shipping and the supply center for the California goldfields. By the 1860s, the region saw a decline in gold production and an increase in agriculture.
The first dredging contracts for the Stockton Deepwater Channel were awarded in 1930. The Port District officially opened on February 2, 1933, when the ship Daisy Grey arrived bringing lumber from Oregon.
During World War II, when an attack on coastal California seemed likely, the U.S. War Department requested some ships be built at an inland port, so many new ships were built at the Port of Stockton area.
Port management recognized the increasing importance of containerized cargo and upgraded dock side facilities. The ship channel was improved in order to accommodate large Panamax class ships.
The Navy Rough and Ready Island Naval Supply Depot built during World War II was phased out of use as a result of special federal legislation sponsored by U.S. Sen. Dianne Feinstein (D-CA) in 1995. It was transferred to the port between 2000 and 2003. This area of the port is now known as the "West Complex".

## Port services
