At a press conference at Celilo Park Monday, two tribes called for removal of the Bonneville, The Dalles, and John Day dams.  On the occasion of “Indigenous Peoples Day,” Yakama and Lummi Nation officials urged the federal government to reject what they called “the offensive doctrine of Christian discovery” that they claim is used to “justify federal actions that impair the rights of Native nations.”  They say the dams were built on a false legal foundation without consent they believe is required under the Treaty of 1855.  The tribal officials also claim the dams decimated the Yakama Nation’s fisheries, traditional foods, and cultural sites.
