Sealaska Constructors, LLC was proud to play a role in restoring this important salmon habitat on the Elwha River.
Sealaska Constructors, LLC completed a National Park Service (NPS) contract to remove several large boulders in Olympic National Park via blasting. The boulders were located in Glines Canyon below the site of a former 210ft hydroelectric dam on the Elwha River and were accessible only by rope and raft. Removal of the boulders cleared the way for upstream fish passage to aid in the ecosystem restoration of the Elwha River.
Historically it is estimated that 400,000 salmon returned to the Elwha River prior to dam construction in the 1920s, but today only about 4,000 return. This contract was a piece of the larger NPS Elwha River Restoration project, which included the largest dam removal in United States history and was the second largest ecosystem restoration effort ever attempted by NPS. Sealaska Constructors, LLC was proud to play a role in restoring this important salmon habitat.
