As we find ourselves in mid-summer with temperatures soaring and no drought relief in sight for most of the state, water is on everyone’s mind. Winter run-off and spring storms may have been scarce, but one source that is reliable and abundant is the water flowing from the volcanic springs in Northern California’s Shasta region. Contributing nearly 700 billion gallons annually to Shasta Reservoir, these cold-water springs are vital to California’s water supply yet they remain poorly understood and unprotected.
After passing through Shasta and flowing into the Central Valley Project, the water that originates in the volcanic springs accounts for about 20% of the summertime flow in the lower Sacramento River. At the current market rate, this spring flow represents a significant financial asset for the state.
The springs are not just important to the state’s water supply, the systems are also telling us something important about the overall health of our watersheds. If there is a healthy wild trout population in the rivers of the Shasta area, we know that our water supply is healthy, too. CalTrout recognizes that there is no time to waste in studying and protecting the irreplaceable and vital source of cold water that these volcanic aquifers represent and has put an action plan in place. That plan, as well as the history of the aquifers, is highlighted in the summer issue of The Current.
I hope you’ll take a few minutes to beat the heat of summer, grab a cold lemonade or beer, and read the issue.

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.
