Figure 2. Lowering of reservoir levels in Lake Aldwell, impounded by Elwha Dam (the lower of the two dams), and Lake Mills, impounded by Glines Canyon Dam (the upper of the two dams), as removal of both dams began over fall 2011 and spring 2012. Lower panel shows river discharge (in green) and cumulative suspended-sediment discharge (sediment suspended in the river flow) in the Elwha River (brown, in kilotons). Tan vertical bars represent activity at the deconstruction site while Elwha Dam was being removed. Figure courtesy of J.A. Warrick, U.S. Geological Survey.
