(Ashland, Ore.) — Southern Oregon University recently hosted the Klamath Dam Removal Research Collaboration Workshop, a follow-up seminar for the numerous groups and agencies working together on the world’s largest-ever dam removal and river restoration project.

The November workshop brought together nearly 150 researchers, Tribal leaders and agency representatives to share information about ecological and social changes in the Klamath River basin that have resulted from the removal of its four dams.

Removal of the Iron Gate (45 minutes southeast of Ashland), J.C. Boyle, Copco No. 1 and Copco No. 2 dams was completed ahead of schedule on Aug. 28, but work will continue for several years to restore about 2,200 acres of land that had been submerged for decades. The dams were built between 1918 and 1962 to provide electricity, but had severe effects on salmon populations and Tribal communities. The river now flows freely from Lake Ewauna near Klamath Falls to the Pacific Ocean.

The three-day event at SOU, held jointly with the Klamath Basin Monitoring Program meeting, was intended to build interdisciplinary connections among those working on the renewal project. The workshop was supported by SOU’s Institute for Applied Sustainability; Department of Environmental Science, Policy & Sustainability; and Native Nations Office.

“Our goal was to foster connections across disciplines and entities, through important keynote talks, focused discussion and field trips to dam removal and restoration sites,” said conference organizer Chhaya Werner, an SOU assistant professor of Environmental Science, Policy & Sustainability.

Werner’s lab researches the regeneration of plant communities in the de-watered reservoirs.

She said many who attended the workshop agreed that its “absolute highlight” was a field trip to the dam removal sites and key spawning tributaries, where dozens of fall-run Chinook salmon could be seen returning to their traditional spawning habitat.

Participants at the event included representatives from 11 tribal agencies or entities, including the Yurok, Hoopa Valley, Klamath, Modoc, Karuk, and lower Elwha Klallam Tribes, and the Pulikla Tribe of Yurok People and Quartz Valley Indian Reservation; seven federal and state agencies; eight universities; and non-profits including the Klamath Bird Observatory, Scott River Watershed Council, Trout Unlimited and Save California Salmon. Many SOU faculty and more than 30 SOU students were actively involved, along with alumni now working in restoration fields.

“SOU’s involvement in hosting the meeting is a showing of (the university’s) commitment to supporting science and communities of the Klamath-Siskiyou bioregion,” said Laurel Genzoli, an SOU alumna and postdoctoral researcher at the University of Nevada, Reno. “Returning to SOU to connect with researchers working together to support the restoration of the Klamath River reminded me of the impact that is made through connecting academic institutions with local communities and real world experiences.”

A focus of the workshop was to acknowledge Tribal research and activism for their roles in dam removal and restoration. Keynote speaker Leaf Hillman, former director of the Karuk Department of Natural Resources, opened the workshop with stories of how the work of dam removal began more than two decades ago. Invited speakers on an Indigenous sovereignty panel addressed questions on inter-entity collaboration and partnership. Ridges to Riffles founder Amy Bowers Cordalis closed the workshop with a powerful reminder to listen and learn from the river and its fish.

The workshop also highlighted ongoing research into sediment transport, fish habitat restoration and social impacts. Participants shared findings, including preliminary data on water quality and juvenile salmon survival, and discussed future collaboration opportunities.

Removal of the four dams was completed on-budget, with the smallest dam taken down in 2023 and the three others dismantled beginning in January 2024. Ongoing restoration work includes reshaping tributary channels, replanting native vegetation and improving habitat for salmon and other species. Progress will be monitored with sonar imaging, netting, radio telemetry and other means of tracking the fish that return to spawn in the Klamath River.
