A short piece in Los Angeles Magazine paints a picture of a Los Angeles River very different from the concrete jungle it’s become today:
Before human civilization transformed it, the L.A. River flowed in some places through grassy oak woodland. In others it coursed through a dense forest of willows, cottonwoods, and sycamores. Steelhead trout swam through its currents, antelope and deer paused at its banks to drink, and grizzly bears ambled into its waters for food.
After a winter storm, the tame stream became a whitecapped fury. In the parched summer months, the river plunged below the surface where it encountered the porous soil of the Los Angeles Basin. But at the Glendale Narrows, shallow bedrock forced the stream aboveground, guaranteeing a year-round flow. In other places, where the parking lots of Beverly Hills, Compton, and Hollywood bake in the sun today, groundwater hydrology conspired with seasonal flooding to create a vast system of marshes, ponds, and other wetlands teeming with plant and animal life.
Today, the Southern California landscape has been transformed and its steelhead and other wildlife have suffered for it.
While we’re in the midst of trying to save what’s left, it couldn’t hurt to pause every once in a while to remember things as they really were.

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.
