Humboldt Bay

Humboldt Bay (Wiyot: Wigi) is a natural bay and a multi-basin, bar-built coastal lagoon located on the rugged North Coast of California, entirely within Humboldt County, United States. It is the largest protected body of water on the West Coast between San Francisco Bay and Puget Sound, the second-largest enclosed bay in California, and the largest port between San Francisco and Coos Bay, Oregon. The largest city adjoining the bay is Eureka, the regional center and county seat of Humboldt County, followed by the city of Arcata. These primary cities, together with adjoining unincorporated communities and several small towns, comprise a Humboldt Bay Area with a total population of nearly 80,000 people. This comprises nearly 60% of the population of Humboldt County. The bay is home to more than 100 plant species, 300 invertebrate species, 100 fish species, and 200 bird species. In addition, the bay and its complex system of marshes and grasses support hundreds of thousands of migrating and local shore birds. Commercially, this second-largest estuary in California is the site of the largest oyster production operations on the West Coast, producing more than half of all oysters farmed in California.

The Port of Humboldt Bay (also referred to as the Port of Eureka) is a deep water port with harbor facilities, including large industrial docks at Fairhaven, Samoa, and Fields Landing designed to serve cargo and other vessels. Several marinas also located in Greater Eureka have the capacity to serve hundreds of small to mid-size boats and pleasure craft. Beginning in the 1850s, the bay was used extensively to export logs and forest products as part of the historic West coast lumber trade, but with the decline of the industry lumber now is only infrequently shipped from the port.
