The Mattole River is a river on the north coast of California. A short section of the river flows through upper Mendocino County, but the vast majority of its 62-mile (100 km) run is through Humboldt County. The river and its 74 tributaries drain about 304 square miles (787 square km), including the eastern side of the King Range, and flows through Mattole Valley before emptying into the Pacific Ocean. For most of its length, the river is only a few miles (~6-7 km) east of the King Range National Conservation Area. About halfway to the ocean, near Honeydew, California, the river passes by Humboldt Redwoods State Park.
Mattole River is located in the southwest corner of Humboldt County. Located 65 miles south of Eureka, there is approximately 26 miles of fishing water from the mouth to the town of Honeydew. The Mattole River with no dams has a wild population of steelhead. Please show respect for what it represents. Mattole River is what rivers in the coastal area were like 50 to 100 years ago. There are no hatchery fish introduced to this river. Catch and Release is the policy for these waters. These wild fish need everyone's help to continue to thrive. Fish and Game strictly enforces all regulations on this river.
