Overview

Humboldt Bay, California’s second largest estuary, is one of the most significant eelgrass bed locations on the U.S. West Coast. It contains some of the most dynamic and productive ecosystems in California. The South Humboldt Bay State Marine Recreational Management Area (SMRMA) lies northwest of Table Bluff. It covers just under one square mile of estuary habitat, including eelgrass beds, intertidal mudflats, and coastal marsh. Topsmelt, surfperch, sculpins, crabs, and clams abound, and birds like the Pacific black brant and surf scoter are common. Visitors to this SMRMA are welcome to go boating, kayaking, rowing, paddle boarding, waterfowl hunting, and wildlife viewing.
