The Klamath River flows 253 miles from Southern Oregon through the mountains of far Northern California where it passes five hydropower dams before ultimately reaching the California coast, draining a basin of more than 10 million acres. The watershed is renowned for its majestic lakes, rivers, fishing opportunities, and strong agricultural economy.


The Klamath River Watershed is home to six federally-recognized Tribes (the Yurok, Karuk, Hoopa, Shasta, and Klamath tribes, plus Quartz Valley Indian Reservation and the Resighini Rancheria) who lived off and tended to the fertile lands for thousands of years before European colonization. Today, Tribal nations control approximately 10 percent of the watershed while 60 percent is managed by public agencies (such as the National Park Service) and 30 percent is privately owned.

Northwestern California and south-central Oregon

Over 10 million acres; drains the third largest river south of Canada flowing into the Pacific Ocean

Communities served:
5 California counties and 3 Oregon counties; most populous towns are Klamath Falls, OR (19,462) and Yreka, CA (7,290)

Key native fish in the watershed:
Chinook salmon, coho salmon, steelhead



On Nov. 17, 2022, an important step was made towards implementing what will soon be the largest U.S. river restoration project to date with the removal of the lower four Klamath River dams. A License Surrender Order for the Lower Klamath River Hydroelectric Project has been issued by the Federal Energy Regulatory Commission. The project license will now be transferred to the States of Oregon and California and the Klamath River Renewal Corporation, the non-profit entity tasked with overseeing dam removal and related restoration efforts. Dam removal is set to begin in early 2023 and by end of 2024, all four Klamath dams will be gone.

Voices of Klamath River Watershed

Hear from individuals that work, play, and/or live in the watershed. 

Featuring videos from Reconnect Klamath, a coalition of groups,
including CalTrout, working to support dam removal and Klamath River restoration. 

"This is my home, where I’ve called home. The Klamath River is where my family is from… I’ve seen the Klamath water in winter and spring when it’s cold, clean, and crystal clear, then later in the year, as the water warms and slows, you start seeing the algae which affects the fish big time. But with restoration, it’s been shown that if you help the river a little, then leave it alone, it will come back. Everything heals in time.”


"Recently I got to work on a project at UC Davis called the State of the Salmonids. Our findings suggest salmon are in a precipitous decline towards extinction. Reconnecting the Klamath watershed represents an immense opportunity to benefit salmon and steelhead as they regain the ability to move up into historically productive spawning and rearing habitat in the upper Klamath watershed. Restoration is not only important for the river itself, but also is really beneficial for the surrounding communities from economic, cultural, and spiritual perspectives."



“Driving up and down the Klamath River’s corridor, you’ll see a lot of defunct fishing lodges, which shows us that at one time, the river was able to support a lot of fishing. I’ve been following the Klamath Dam removal project for a while. Our business of taking people fishing will be affected by it in the short run, but I am perfectly willing to give up a couple years of guiding this river if that’s what it takes to get it to recover. I’m excited to see the Klamath River go through a great change for the better.”



CalTrout in the Klamath River Watershed

CalTrout is working to protect and revitalize the Klamath River Watershed by addressing major threats to its health including fish passage barriers from the Klamath dams, loss of critical habitat, and water mismanagement. While dam removal is a critical part of reviving the health of the watershed, so is restoration of important Klamath River fish spawning and rearing tributaries like the Shasta and Scott rivers. This will allow fish to more easily access and recolonize the upper Klamath River above the dams.
