Native Fish Conservation - Klamath Anadromous Fisheries Reintroduction Project

Four hydroelectric dams (Iron Gate Dam, Copco 1 and 2, and J.C. Boyle Dam) were removed in 2024, opening hundreds of miles of historical habitat for Chinook Salmon, Coho Salmon, Steelhead Trout, and Pacific Lamprey that had been blocked for over 100 years. Oregon Department of Fish and Wildlife and its partners are monitoring the repopulation of fish into this historic habitat. This page contains monitoring updates, reintroduction plans, and reports about this project.

Reintroduction Plans

• A Plan for the Reintroduction of Anadromous Fish in the Upper Klamath Basin (pdf)
• Implementation Plan for the Reintroduction of Anadromous Fishes into the Oregon Portion of the Upper Klamath Basin (pdf)

Selected hydrography of the Klamath Basin, including the distinction between the upper (upstream of Iron Gate Dam) and lower basin (downstream of Iron Gate Dam). Locations of dams in the Klamath Hydroelectric Project that are to be removed in 2023 (Iron Gate Dam, Copco1 and 2 Dams, and J.C. Boyle Dam) are highlighted in red, and other major dams in the Klamath Basin are shown. The current upstream extent of anadromous fishes is Iron Gate Dam. ODFW map illustration Dec. 2022.

Selected hydrography of the Upper Klamath Basin with Klamath River mainstem dams. The Upper Klamath Basin is defined as that portion of the Klamath Basin above the site of Iron Gate Dam, which excludes anadromous fishes. Dams (Iron Gate, Copco 1 and 2, and J.C. Boyle Dam) planned to be removed in 2024 are highlighted in red. Potential existing streams with suitable anadromous fish habitat are highlighted in red.ODFW map illustration Dec. 2022.
