Skeena River The Skeena River is the second-longest river entirely within British Columbia, Canada (after the Fraser River). Since ancient times, the Skeena has been an important transportation artery, particularly for the Tsimshian and the Gitxsan—whose names mean "inside the Skeena River" and "people of the Skeena River," respectively. The river and its basin sustain a wide variety of fish, wildlife, and vegetation; and communities native to the area depend on the health of the river. The Tsimshian migrated to the Lower Skeena River, and the Gitxsan occupy territory of the Upper Skeena.
