With most of California’s rivers already dammed, the state of the fisheries below those dams is of concern to California’s fly fishermen — many of whom don’t know that section 5937 of California Fish & Game code specifically provides for healthy fisheries below dams.
“The owner of any dam shall allow sufficient water at all times to pass over, around, or through the dam, to keep in good condition any fish that may be planted or exist below the dam.”
—California Fish and Game Code § 5937
This informative article from the California Water blog features fisheries uber-scientist Peter Moyle* and Legal Eagle Brian Gray**, who spell out the power of 5937 — and why it hasn’t always protected fisheries:
The simple language of Section 5937 makes it one of the clearest laws in California. Versions of this law have been around since the 19th century and it was repeatedly strengthened until the present version became law in 1957. Section 5937 seems to provide clear protection for California fishes below dams. So why are we still wrangling over issues of how dams affect fish more than 120 years after the first version of the Code was written?
The article does a wonderful job of detailing the 60-year fight to restore the San Joaquin River’s now extinct Coho salmon runs below Friant Dam, including the threats to the current restoration program.

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.
