Dams have a notorious reputation; there’s a long history of environmental damage caused by dams, from blocking migrating fish to withdrawing access to Indigenous people.
It’s safe to say that the controversy surrounding dams is a complicated one. In a surprising move, many conservation groups are now working with the hydropower industry to find common ground. There is a good opportunity here to upgrade some existing dams to generate power, while also tearing down inefficient dams and making others more fish-friendly.
“The hydropower structures that we have, some make more sense than others. Some do bigger damage than others. Some generate more [energy] than others. In some places, we’re going to have to invest in infrastructure. But let’s also invest in undoing some things that never should have been done in the first place,” explains Curtis Knight, CalTrout’s Executive Director in a recent article on hydropower in the LA Times.
Recently, a $64-billion-dollar proposal was made between conservationists and the industry which includes $18 billion for safety improvements at potentially hazardous dams, $15 billion to fund the removal of 2,000 dams, and $24 billion to support federal agencies, in part by helping them produce larger amounts of clean electricity at existing hydropower facilities.
It’s imperative that these additions to hydropower capacity are also paired with investments in healthier and more free-flowing rivers.

Peter Moyle is the Distinguished Professor Emeritus in the Department of Wildlife, Fish and Conservation Biology and Associate Director of the Center for Watershed Sciences, at UC Davis. He is author or co-author of more than 240 publications, including the definitive Inland Fishes of California (2002). He is co-author of the 2017 book, Floodplains: Processes and Management for Ecosystem Services. His research interests include conservation of aquatic species, habitats, and ecosystems, including salmon; ecology of fishes of the San Francisco Estuary; ecology of California stream fishes; impact of introduced aquatic organisms; and use of floodplains by fish.
Robert Lusardi is the California Trout/UC Davis Wild and Coldwater Fish Researcher focused on establishing the basis for long-term science specific to California Trout’s wild and coldwater fish initiatives. His work bridges the widening gap between academic science and applied conservation policy, ensuring that rapidly developing science informs conservation projects throughout California. Dr. Lusardi resides at the UC Davis Center for Watershed Sciences and works closely with Dr. Peter Moyle on numerous projects to help inform California Trout conservation policy. His recent research interests include Coho salmon on the Shasta River, the ecology of volcanic spring-fed rivers, inland trout conservation and management, and policy implications of trap and haul programs for anadromous fishes in California.
Patrick Samuel is the Conservation Program Coordinator for California Trout, a position he has held for almost two years, where he coordinates special research projects for California Trout, including the State of the Salmonids report. Prior to joining CalTrout, he worked with the Fisheries Leadership & Sustainability Forum, a non-profit that supports the eight federal regional fishery management councils around the country. Patrick got his start in fisheries as an undergraduate intern with NOAA Fisheries Protected Resources Division in Sacramento, and in his first field job as a crew member of the California Department of Fish & Wildlife’s Wild and Heritage Trout Program.
