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 […]

BAY DELTA SCIENCE CONFERENCE: Dark Carbon and a Return to Abundance: How Detrital Floodplain Food Webs Can Help Recover Endangered Fish

In the pre-development Central Valley, winter-spring flooding once created a vast mosaic of productive wetland habitats that teemed with fish and wildlife. A major driver of this wildlife abundance was terrestrial carbon made available to aquatic food webs when floodplains were inundated. Nineteenth and twentieth-century investments in drainage and a network of dams, canals, and levees transformed the Central Valley’s […]

BAY DELTA SCIENCE CONFERENCE: Monitoring and Managing Sea-Level Rise Impacts on Tidal Marshes in the San Francisco Estuary

Once not all that long ago, the prevailing thought was that if tidal marsh remnants were protected and carefully managed, they would persist for the foreseeable future, providing sanctuary for tidal marsh species that are at-risk due to habitat loss and fragmentation. However, a series of recent independent studies have demonstrated that mature marshes are vulnerable to marsh drowning due […]

BAY DELTA SCIENCE CONFERENCE: Science-Based Regulatory Permitting for Resilient Tidal Habitat Restorations

The permitting of tidal restoration projects is most often a costly and time-consuming process, causing substantial delays in implementation while endangered and threatened species remain at risk. Given the accelerating nature of sea level rise, restoration of tidal habitats that are resilient to climate change should be implemented on a large scale and soon to have any chance of contributing […]
