Restoring the Klamath River: A Historic Milestone

Stantec is supporting the restoration design for five major fish-bearing tributaries of the Klamath River as part of the largest dam removal and river restoration project in US history. Working as a subcontractor to Resource Environmental Solutions (RES), Stantec’s efforts follow the 2023 removal of four dams, which reopened over 400 miles of historical habitat vital for salmon and other native fish. The Klamath River Renewal Corporation (KRRC) and RES are overseeing the restoration, collaborating with local Indigenous groups.

The creek restoration targets Beaver, Jenny, Spencer, Camp, and Scotch Creeks, whose channels were submerged by reservoirs for over a century. Efforts include reconnecting these tributaries to the main river, enabling fish passage, reshaping 18,000 feet of stream channel, and removing 150,000 cubic yards of sediment from former reservoir beds.

In 2024, RES began revegetating about 2,200 acres of previously flooded land, including more than 1,000 acres set to return to tribal ownership through an agreement with the Shasta Indian Nation. These activities support the cultural and ecological importance of the Klamath River for local tribes such as the Karuk, Yurok, Shasta, Klamath, and Modoc, who rely on the river’s fisheries. The short film, Restoring Balance, documents the collaborative restoration efforts.
