In August of 2022, the Federal Energy Regulatory Commission (FERC) released its Final Environmental Impact Statement for the surrender and decommissioning of the Lower Klamath Project which consists of the removal of four dams on the lower Klamath River, J. C. Boyle, Copco #1, Copco #2, and Iron Gate (FERC 2022), the largest dam removal project in American history.

Since August of 2022, there has been a substantial amount of progress made toward removing the dams. The project broke ground in June 2023 when FERC issued approval to start the deconstruction of Copco No. 2 Dam, a diversion dam located above Copco No. 1 Dam. The deconstruction was complete by the beginning of November 2023 (KRRC 2023) and work has not slowed since.  Drawdown of the three reservoirs was initiated in January and completed by February 15 of this year, allowing for continued progress toward the deconstruction of the remaining dams.

Spring run-off prevented the start of deconstruction on Iron Gate and J.C. Boyle Dams due to the fact that the dams are earthen and would be impacted by high flows (KRRC 2024); however, the deconstruction of Copco No. 1 started on March 11, 2024, and is expected to be fully completed by August of 2024. Copco No. 1 is a concrete arch dam and can be removed even while high spring flows are present.

FERC provided authorization on April 26, 2024 (FERC 2024a) to begin the partial deconstruction of Iron Gate Dam and work began on the dam removal on May 1, 2024.  Additionally, on May 2, 2024 FERC authorized the removal of the J.C. Boyle Development (FERC 2024b), which is anticipated to be completed in the fall. 

The Klamath River supports three salmonid species including chinook, steelhead, and federally Threatened coho; the hope is that the removal of the remaining three dams will be complete before the start of the fall run of chinook salmon upriver.
