Ten Native Americans set fishing nets in the Nisqually River, in defiance of Washington state law.

From MOHAI: "On September 4, 1968, about ten Native Americans set fishing nets in the Nisqually River, in defiance of Washington state law. They were supported by a group of about 50 people, representing the Peace and Freedom Movement, Students for a Democratic Society (SDS), the Black Panther Party, and the Socialist Workers Party, who provided guards to prevent confiscation of the fishing nets by the State Fisheries Department. The following day, the nets were temporarily pulled from the river while the fishermen and their supporters traveled to the State Capitol in Olympia to protest in favor of Native American fishing rights."
