Office of Chehalis Basin

Reducing flood damage and restoring aquatic life in the Chehalis River Basin

Housed within the Washington Department of Ecology, Office of Chehalis Basin (OCB) serves as the focal point for actions and plans successfully reducing flood-related damage and restoring aquatic life throughout the Chehalis River Basin. 

OCB works hand in hand with the independent Chehalis Basin Board, administers state funding, and leads a coalition of local, Tribal, and state partners to implement the long-term Chehalis Basin Strategy to protect and preserve Chehalis River Basin for people, fish, and communities today, and for generations to come.
