About the mattole river
The Mattole River is a 62-mile-long river located in Northern California that flows through the scenic Mattole Valley. Historically, the Mattole Valley was home to the indigenous Mattole people who lived along the river for thousands of years. The river is unique in that it is one of the few undammed rivers left in California, allowing for a relatively natural flow regime. The Mattole River watershed provides critical habitat for threatened and endangered species, including coho and Chinook salmon, steelhead trout, and the Pacific lamprey. There are no major reservoirs or dams on the river, and the water is primarily used for agriculture and recreational purposes such as fishing, swimming, and river rafting.
