The Mattole Salmon Group is a community based non-profit organization that has been working in the Mattole River watershed for 30 years to restore salmon populations to self sustaining levels in the Mattole River watershed. The organization works to ensure that rivers in and around the King Range National Conservation Area can sustain healthy populations of salmon and works on large scale river restoration projects, public education, and water storage and usage in the watersheds that surround the King Range. The organization is part of the Mattole River and Range Partnership.
