Iron Gate Dam is an earthfill hydroelectric dam on the Klamath River in northern California. It is the lowermost of a series of power dams on the river, the Klamath River Hydroelectric Project, operated by PacifiCorp. It also poses the first barrier to migrating salmon in the Klamath.

The Iron Gate Dam along with the John C. Boyle Dam are two of four on the Klamath River that would be removed under the Klamath Economic Restoration Act.[1] As of February 2016, the states of Oregon and California, the dam owners, federal regulators and other parties reached an agreement to remove all four dams by the year 2020, pending approval by the Federal Energy Regulatory Commission.[2]
