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 […]

DR. JEFF MOUNT: Ecosystem Water Budgets: A Novel Approach to Managing Water for the Environment

Dr. Jeff Mount has a long history of involvement with science issues in the Delta.  As a professor at UC Davis, he started the Center for Watershed Sciences, which became home to researchers working on the Delta; he was on the first iteration of the Delta Independent Science Board and eventually became its chair; and he has been a very […]

BROWN BAG SEMINAR: Developing Tiered Environmental Flow Criteria Using a Functional Flows Approach for California Streams

Establishing environmental flow targets to protect aquatic communities is a priority for numerous programs in California including in the Delta. In this first of three brown bag seminars focusing on flow targets and ecology, Dr. Yarnell discusses her recent work using a functional-flows approach to develop statewide environmental flow recommendations. The approach allows for the rapid development of flow regimes […]

Integrated ecosystem modeling for adaptive management: Lessons from 40 years of decision support in the Great Lakes

Limnotech’s Dr. John Wolfe presents two case studies from the Great Lakes which utilized integrated modeling and adaptive management to solve ecosystem issues The Sacramento-San Joaquin Delta is no doubt a complex ecosystem, but it certainly is not the only one; the complexity and uncertainties facing the Bay-Delta system present challenges similar to those in the Great Lakes system.  In […]

Ecosystem Modeling to Support Adaptive Management – Lessons from 40 years of Decision Support for the Great Lakes

Managing large interconnected systems of water bodies presents complex challenges, and model simulations are an essential tool.  For many years, the Great Lakes community has used models to support management of their system.  The complexity of the Bay Delta system presents similar challenges. Adaptive management will be critical, given climate change and other uncertainties.  This presentation provides lessons learned from […]

PPIC Panel: Permitting a Solution: Regulatory Oversight in the Delta

In April of 2013, the Public Policy Institute of California released the report, Stress Relief: Prescriptions for  Healthier Delta Ecosystem, which noted that the state is at a critical juncture with adoption and forthcoming implementation of the first “Delta Plan” and a decision on the BDCP possible by early next year.  “But California still faces an uphill battle to incorporate […]
