CalTrout scored another legislative victory on June 27, 2018 when Gov. Jerry Brown officially designated Northern California’s Mokelumne River as a Wild and Scenic River. The designation applies to 37 miles of the North Fork Mokelumne and main stem running through Amador and Calaveras counties.
Perhaps relatively unknown, the Mokelumne is an important river, supplying water and power to tens of thousands of Californians in the foothills, Central Valley, and the entire East Bay of San Francisco. The river offers critical, cold-water habitat for native salmonids. It is neither stocked nor managed as a fishery in any of the protected sections, yet robust populations of wild trout persist in all of these reaches. This is a testament to the quality of the habitat and presence of cold, clean water.
Under California’s Wild and Scenic Rivers Act of 1972–one of CalTrout’s earliest victories in legislative advocacy–Mokelumne River’s extraordinary scenic, recreational, and wildlife values will be “preserved in their free-flowing state for the benefit and enjoyment of people of this state”, and its waters on the five designated segments will be closed off to construction of new on-stream dams and major water diversions.

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.
