“The treaties grant the tribes a right, in perpetuity, to access their traditional fishing grounds,” McKenna said. “The two questions that have been litigated over the last 40-plus years have to do with how much of the fish they are entitled to. In the Boldt decision, it was decided they are entitled to half. Then, in this case, that went to the Supreme Court, the question is what happens when there are fewer fish to catch because of something the state has done. In this case, building culverts under state highways, and on park land, and lands owned by the State of Washington.”
