Washington state is where collaborative governance on natural resources began in the early 1970s, with a groundbreaking agreement to resolve conflicts over flood control on the Snoqualmie River. As the new field grew, it helped to resolve a key civil rights struggle over tribal fishing rights in Washington known as the “Fish Wars,” which came to a head in a landmark legal case referred to as the Boldt Decision. After the US Supreme Court upheld the Boldt Decision’s recognition of tribal treaty rights, the parties eventually turned to collaborative governance to resolve their conflict, and the resulting state/tribal co-management of salmon and steelhead persists to this day. Since then, collaborative approaches in Washington have led to many groundbreaking outcomes, greatly influencing the rest of the nation over a 50-year history.
