Elwha River  The Elwha River is a river on the Olympic Peninsula in the U.S. state of Washington. From its source at Elwha snowfinger in the Olympic Mountains, it flows generally north to the Strait of Juan de Fuca. Most of the river's course is within the Olympic National Park. The Elwha is one several rivers in the Pacific Northwest that hosts all five species of native Pacific salmon (chinook, coho, chum, sockeye, and pink salmon), plus four anadromous trout species (steelhead, coastal cutthroat trout, bull trout, and Dolly Varden char). From 1911 to 2014, dams blocked fish passage on the lower Elwha River. Before the dams, 400,000 adult salmon returned yearly to spawn in of river habitat. Prior to dam removal, fewer than 4,000 salmon returned each year in only of habitat below the lower dam. The National Park Service removed the two dams as part of the $325 million Elwha Ecosystem Restoration Project. Dam removal work began in September 2011 and was completed in August 2014. The river has already carried sediment to its mouth, creating 70 acres of estuary habitat at the Strait of Juan de Fuca. The first documented use of the name Elwha River dates to Henry Kellett's 1846 map. The Elwha River begins at the Elwha snowfinger near Mount Barnes and Mount Queets in the Olympic Range within Olympic National Park, in Jefferson County, Washington. The river flows southeast, then curves northward for the great majority of its course, with its mouth at the Strait of Juan de Fuca. Major peaks near the Elwha's source include Mount Christie, Mount Carrie, Mount Meany, and Mount Seattle. After receiving the tributaries Delabarre and Godkin creeks, the Elwha River flows northward. The Hayes River joins in Press Valley, where the Hayes River Ranger Station is located. Lost River joins near the northern end of Press Valley, after which the Elwha crosses into Clallam County, Washington. Just after the county line, the Elwha River passes the Elkhorn Ranger Station and enters the Grand Canyon of the Elwha. As the river leaves the Grand Canyon, it is crossed by Dodger Point Bridge. Humes Ranch Cabin is located near the river along the Geyser Valley trail. After passing Krause Bottom, the river enters Rica Canyon at Goblins Gate. Prior to dam removal, the river fanned out into a delta below Rica Canyon, at the head of Lake Mills, the reservoir behind Glines Canyon Dam.
