Dam removal will allow the Elwha to once again transport sediment from the high mountains to the sea, a process that maintains the river's natural form and function. Here, the Elwha in July slices through sediment exposed as reservoirs were drained to prepare for dam removal. It's just a fraction of the 24 million cubic yards of trapped sediment that must be managed by controlling the pace of dam removal.
