(Washington, D.C.) -- The Federal Energy Regulator Commission has given final approved to a plan that will remove four dams on the Klamath River in Oregon and California. The order has been 15 years in the making and includes PacifiCorp, fishing groups, tribes and other stakeholders. The first dam is expected to be removed by next summer and the three remaining dams will be removed in 2024. The approval allows licensing of the dams to be transferred from PacifiCorp to the nonprofit Klamath River Renewal Corporation which will carry out the work to remove the dams.
