The Klamath River Basin was once home to one of the West's most prolific salmon fisheries. But for more than a century, efforts to harness the natural power of the river through the installation of hydroelectric dams, have contributed to devastating declines in water quality, the region’s anadromous fisheries, and the tribal, recreational, and commercial economies and communities they support. 

Work to improve fish passage has been underway for many years in the Basin, and each fish passage project completed over the past two decades has contributed to opening up and restoring additional fish habitat throughout the Klamath Basin. The California Fish Passage Forum has compiled project information for sites remediated between 2000 and 2020. These projects, and the resulting realized and potential habitat gains are illustrated in the animated map below. 

The projects being profiled in this StoryMap have been led, implemented and supported by a wide variety of organizations. Many of these groups are identified below, but these efforts to improve connectivity in the Klamath Basin would not have been possible without the support of countless individual local landowners, consultants, funding sources, academic institutions, and contractors. We apologize for any omissions, and strive to identify all that have contributed.

Many thanks to the groups who submitted project information for this effort.
