The Nez Perce Tribe continued its campaign Wednesday to restore the lower Snake River to its free-flowing form with the launch of its Salmon Orca Project website and a plea to President Joseph Biden.

The tribe has long called for breaching the dams as the best way to restore threatened and endangered salmon and steelhead runs. Last spring, it backed Idaho Rep. Mike Simpson’s effort to remove the dams and compensate affected industries and communities. The tribe also organized the Salmon Orca Summit, a gathering of dozens of tribes throughout the Pacific Northwest in July, and was able to secure resolutions backing Simpson’s concept from the Affiliated Tribes of Northwest Indians and National Congress of American Indians.
