Project Description

Klamath Dam removal stands out as one of the most promising salmon recovery opportunities in the history of California Trout. Since 1917, the four Klamath Dams have blocked access to hundreds of miles of salmon and steelhead productive habitat. It has diminished the productivity of the Klamath River and its tributaries, blocked spawning grounds, and blocked off cold source water. Beyond loss of habitat, Iron Gate Dam now serves as a giant heat sink that creates water quality problems, including toxic algae blooms. The decommissioning and removal of the Klamath Dams not only makes economic sense, but would greatly benefit the Klamath-origin salmon fisheries and all other Klamath Basin public resources that have been adversely affected by these dams over the past century.
