# Event Details

- **Event Name**: Food web responses to Klamath Dam removal
- **Event Start and End Date**: Thu, 20 Nov, 2025 at 07:00 pm
- **Event Description**: Join us Thursday, November 20, at 7:00 p.m. for a presentation by Alison O'Dowd entitled “Food web responses to Klamath Dam removal: an examination of salmonid food resources downstream of Iron Gate Dam.“ The removal of four hydroelectric dams on the Klamath River was the largest dam removal in U.S. history.  Klamath dam removal has improved water quality and salmonid access to habitat, but sediment fluxes associated with dam removal were predicted to have short-term negative impacts on habitat and water quality downstream of former dam sites. This talk will explore food web responses to Klamath dam removal downstream of Iron Gate Dam during a critical period of juvenile salmonid growth and outmigration in the late spring. Results from this study are intended to inform future dam removals that may impact sensitive life stages of anadromous fish and their invertebrate prey. Alison O'Dowd is a Professor at Cal Poly Humboldt in the Environmental Science & Management department. Her research focuses on benthic macroinvertebrates as a way to assess river health and food resources for salmonids. Programs are held at Six Rivers Masonic Lodge, 251 Bayside Road, Arcata. Drinks and goodies are served at 7:00 p.m., the program begins at 7:30. You can also find it on Zoom—go to rras.org for the link.
