BAY DELTA SCIENCE CONFERENCE: Drought, climate change, and restoration resiliency

John Durand looks at the effects of the 2012-2016 drought on the Delta from the environmental, economic, and stakeholder perspectives The 2012-2016 drought is one for the records in that, while not necessarily the driest or the longest for California since the state has been keeping records, it was the hottest drought with many scientists saying that we can expect […]

BAY DELTA SCIENCE CONFERENCE: Emergent groundwater and sea level rise in the San Francisco Bay Area: the silent and largely unknown underground threat

The threats that sea level rise poses to coastal development from direct inundation are better understood than the threats due to rising groundwater levels. Rising sea level will raise the level of groundwater in coastal aquifers, resulting in damage to buried infrastructure and increased potential for flooding from groundwater inundation. Researchers at UC Berkeley and Silvestrum Climate Associates have performed […]

BAY DELTA SCIENCE CONFERENCE: Checking assertions with data: Untangling factors that constrain water exports from the San Francisco Bay estuary

In recent years, media reports and editorials have suggested that environmental regulations have made Delta outflows increasingly large, project water exports are frequently limited or even halted by regulations to protect endangered species, and that regulations designed to protect endangered species, the Delta Smelt in particular, are the principal restrictions on exports and are thus responsible for most of the […]

BAY DELTA SCIENCE CONFERENCE: Developing a Delta habitat restoration adaptive management program

Presentation covers what is adaptive management, why is it important, and why an adaptive management program is needed Habitat restoration is a key strategy in the Delta Plan to achieve the coequal goal of protecting, enhancing, and restoring the Delta ecosystem. Various efforts, including the California EcoRestore initiative and Proposition 1 grants administered by the Delta Conservancy and Department of […]

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: Advancing Tidal Wetland Restoration in a Regional Adaptive Management Framework

Dr. Gerrit Platenkamp: Adaptive management in a regional context faces challenges with monitoring, experimentation, and adaptation At the Bay Delta Science Conference, Dr. Gerrit Platenkamp, Director of Biological Resources at ESA, gave this presentation on adaptive management and wetland restoration from a practitioner’s perspective.  “We’ve collectively worked on thousands of acres of tidal marsh restorations that have been put in […]

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 […]
