… The [Round Valley Indian] tribal nation is confronting the Trump administration over the [Eel] river’s future and fighting some of its regional allies to reclaim water rights that have been overlooked for a century. … The struggle is taking place as the entity with a dominant stake in the river for generations, Pacific Gas & Electric Co., seeks to give up in Lake and Mendocino counties its network of Eel River dams and a linked hydropower plant. The move has triggered a federal review that has pitted the tribes, together with environmental groups in favor of dam removal, against farming interests, reservoir supporters and the Trump administration, which has taken a dim view of dam demolition.
