Throughout our first 50 years, CalTrout has grown from a handful of activist volunteers to a $15M organization leading major conservation projects all across California. In the process, we’ve developed a working model that uniquely positions us to take on these challenges, and succeed.
Our regionally based structure means we’re embedded in communities where native fish are critical to the region, investing significant time cultivating relationships. Our work is rooted in science and hard data that drives our decision-making and measures our efficacy. Together, this formula builds trust among those with whom we work, and allows us to bring diverse interests together with a shared goal in mind. The Cal Trout Ethos combines this model with a bold and competent attitude – it’s a belief that no project is too big, no task too daunting.
Leading the Way Forward
Our plans for the next 50 years are even bolder, and are built up on our understanding that–as conservationists, as scientists, as humans–we must work with and integrate landscape-level processes into our way of life, rather than attempting to dominate them. And as we respond to the impact felt by a growing population, climate change, and an altered water system, we must move from treating symptoms to treating the causes.
Not only will we continue to implement our projects at scale, we will do so in a way that policy and projects work together with nature to achieve results that benefit people and the environment. We must reconcile a knowledge of nature into our management of nature, across all of our disciplines. That means partnering with foresters, ranchers, farmers and urban city planners in developing urban infrastructure. It means removing barriers to free-flowing waterways while delivering water where it’s needed. It means working across the entire California landscape–from ridge top to river mouth–from the Oregon border to San Diego.
In the era of climate change, we have the capacity to demonstrate to the world what solutions look like by continuing to scale our proven model, and by continuing to integrate the concepts by which people manage diverse landscapes – be they farms, ranches, cities, or forests.
Our Future Vision
At CalTrout, we envision a California where waters flow free, clean and cold from headwaters to the ocean: a water system in perfect balance, serving the needs of all who depend on it.
With your support, we will build on what we have accomplished–ensuring clean, cold waters run free throughout California as we save our native wild fish from extinction. Because a healthy fish population signifies a healthy and sustainable water system. And that means a healthy, sustainable future for California that we can hand off to our children, our grandchildren, and all future generations of Californians.

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.
