In 2011, the largest dam removal in U. S history began on the Elwha river located in Washington State. Now, the ecosystem is thriving on the river since the removal of its hydroelectric dam system. The video shows clearly how the ecosystem is now thriving in Washington State. There are many surveys also that show dramatic recovery, especially at the of the river. The reason is very simple; the flow of sediment has created favorable habitat for the salmon population. There are many endangered species of salmon that are now present in the river. Environmentalists believe that removal of dam on Elwha river will be a golden example for the removal of other dams across U.S. Below are the few things listed that you should know about Elwha river,
- The river is a 72 KM long river situated on the Olympic Peninsula in the U.S. state of Washington.
