BAY DELTA SCIENCE CONFERENCE: Lost in translation: The art of interpreting complex science for policymakers

Effectively communicating complex science to policy- and decision-makers is critical for managing the Delta, but the science needs to be useful as well as usable.  The State of Bay-Delta Science (SBDS) is a synthesis of current scientific understanding of the Bay-Delta; it brings together progress on key research questions, identifies knowledge gaps, and explores policy implications of current science and […]

BAY DELTA SCIENCE CONFERENCE: Before and After: Evaluating the effect of the 1995 Delta spring standards on actual outflows into San Francisco Bay

Dr. Tina Swanson gives her analysis of the standard; has it really resulted in increased Delta outflow? Fresh water flowing into the Delta is highly contested and tightly managed. The current regulations for spring outflows were established in 1995, following a severe multi-year drought, lawsuits, fish population declines and several Endangered Species Act listings. These new standards were designed to […]

BAY-DELTA SCIENCE CONFERENCE: Problems and promise of restoring tidal marsh to benefit native fishes

Dr. John Durand discusses the effectiveness of existing and proposed tidal marsh restoration sites in the Suisun Marsh and the Delta Implementing aquatic restoration projects that scale appropriately with seasonal flows, tidal energy, and food production remains a challenge in the highly disturbed Sacramento-San Joaquin Delta and Suisun Bay. Many restoration projects may achieve aesthetically pleasing results that will offer […]

BAY DELTA SCIENCE CONFERENCE: The effects of water project operations on juvenile salmon survival in the Delta

Literature, data review, and recommendations for future salmonid investigations Survival for migrating juvenile chinook salmon has been low for those on the San Joaquin River, averaging approximately 5% since 2002.  Survival is more variable for Sacramento River chinook salmon, and survival data are limited for steelhead.  While water export operations contribute to salmonid mortality by way of direct mortality at […]

BAY DELTA SCIENCE CONFERENCE: Managing the state and federal water projects: The Collaborative Science and Adaptive Management Program

Part 1: Collaborative Science and Adaptive Management Program: Moving from Litigation to Collaboration The Collaborative Science and Adaptive Management Program (CSAMP) is an applied science program specifically designed to inform decisions regarding operations of the State Water Project and the Central Valley Project and species protection in the Delta. The Program was established in 2013 as an outgrowth of litigation […]

BAY DELTA SCIENCE CONFERENCE: A Tale of Two Deltas: A Comparison of Transport Processes in the Predevelopment and Contemporary Delta

Modification of the Delta’s landscape has fundamentally changed hydrodynamic and transport processes in the Delta. In this presentation, Jon Burau, Project Chief for the USGS, compares the transport processes in the historical and contemporary Delta based on insights gained from field experiments and numerical model results. Jon Burau began by noting that the predevelopment Delta was a dendritic system, which […]

BAY DELTA SCIENCE CONFERENCE: The scientific challenge of establishing appropriate baselines for restoration

Ecosystem restoration generally seeks to reestablish structures and processes in ecosystems that have been degraded by human activities. The success of the project is usually measured by comparing the current conditions to specific targets that were chosen to reflect desired ecosystem states. While such comparisons are convenient for developing restoration strategies and measuring success, they often lead to the assumption […]
