DR. GLENDA HUMISTON: Managing our Lands to Manage our Water

Dr. Glenda Humiston is Vice President of Agriculture & Natural Resources for the University of California. At the 2019 California Irrigation Institute conference, Dr. Humiston was the opening keynote speaker, and in her speech, she talked about work being done to address drought vulnerability, the importance of managing watersheds, the goals of the California Economic Summit, and the promising future of biomass.

She began by saying that we have known for a long time that water insecurity is a huge issue, and not just due to climate change or droughts; it’s also policy, regulations, allocations and technology – there are a lot of issues and managing the effects of it are very challenging.

BAY DELTA SCIENCE CONFERENCE: Smelt in Hot Water: Is Thermal Stress the Final Blow for Delta Smelt?

Studies show fall water temperatures may play more of a role in Delta smelt survival than flow augmentation

Managing freshwater outflow in late winter-early spring to maintain the Low-Salinity Zone in Suisun Bay has been one of the primary management strategies for supporting Delta Smelt and their habitat. Meanwhile, fall flows have declined over time due to freshwater exports and the Low-Salinity Zone has been located upstream where physical habitat is thought to be poor quality. As a result, fall flows in wet/above normal years are now mandated by the 2009 BiOP to maintain the Low-Salinity Zone no less than 74km in September and October. Since 2009, this has occurred twice – in 2011 and 2017.  In 2011, the Delta smelt rebounded but not in 2017.  While 2011 and 2017 were both wet years, summer water temperatures in 2017 were near the thermal limit for Delta smelt throughout the estuary, while 2011 was much cooler, suggesting temperature may be an important factor for Delta smelt survival.

Dr. James Hobbs is a Professional Research Scientist and Lecturer in the Department of Wildlife, Fish and Conservation Biology, UC Davis.  At the 2018 Bay Delta Science Conference, he gave this presentation which looked at the role that temperature might play in the decline of the Delta smelt.
