PANEL DISCUSSION: Upgrading the water grid

In September of 2018, the Public Policy Institute of California (PPIC) released the report, Managing Drought in a Changing Climate: Four Essential Reforms, which asserted there are five climate pressures affecting California’s water: Hotter temperatures, a shrinking snowpack, shorter and more intense wet seasons, rising sea level, and more volatile precipitation—with wetter wet years and drier dry years.  In response, […]

BAY DELTA SCIENCE CONFERENCE: Drought Resistance and Resilience in the Delta Fish Community for over 5 Decades

The 2012-2016 California drought was unprecedented in severity. In the San Francisco Estuary, the drought was characterized by elevated nutrient loads, depressed zooplankton densities, enhanced Microcystis blooms, and an expansion of invasive aquatic vegetation coverage. Did wet conditions in 2017 allow the system to return to pre-drought conditions? Furthermore, has the capacity for drought resilience in the SFE changed over […]
