BAY DELTA SCIENCE CONFERENCE: Restoration in the Cache Slough Complex: The Yolo Flyway Farms Restoration Project

The Yolo Flyway Farms Restoration Project involves restoring and enhancing approximately 278 acres of tidal freshwater wetlands at the southern end of the Yolo Bypass within the Cache Slough Complex. The Project seeks to partially restore historical ecological functions in this highly altered regional landscape. The Project will involve minimal excavation of approximately 65,000 cubic yards of soil to provide […]

BAY DELTA SCIENCE CONFERENCE: Franks Tract feasibility study: Applying the guidance of a Delta Renewed

One of the elements of the 2016 Delta Smelt Resiliency Strategy is assessing the feasibility of restoring Franks Tract.  The Franks Tract feasibility study was completed and released in June of 2018 by the Department of Water Resources.  The conceptual design for the project relies on the guidance of the San Francisco Estuary Institute’s A Delta Renewed.  At the 2018 […]

BAY DELTA SCIENCE CONFERENCE: Restoration Planning for the Sacramento –San Joaquin Delta and Suisun Marsh: Considering the Implications of Climate Change

The Delta Reform Act requires ‘taking into consideration the physical changes that have occurred in the past and the future impact of climate change and sea level rise’ for restoration planning. Re-establishment of tidal marsh is critical to restoring food web function and increasing the extent of habitat for fish and wildlife within the Delta and Suisun Marsh; however, land […]

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 […]

BAY DELTA SCIENCE CONFERENCE: A Review of Water Quality Science in the Delta: Chemical contaminants and nutrients

As part of its charge to review science activities that support adaptive management in the Delta, the Delta Independent Science Board (DISB) has completed a review of the scientific basis for assessing water quality in the Delta.  The review focused on chemical contaminants and nutrients and assessing how water quality information is being used in management decisions, especially for  supporting […]

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: Working With Nature Across the Land Use Spectrum: A Holistic Approach to Ecological Resilience

Many approaches to ecological restoration and enhancement of ecosystem services focus on particular parts of the landscape, such as open spaces high in watersheds, urban areas, agricultural areas, waterways, or shorelines. This approach to dividing up large physical and ecological systems might be easier to manage, but may fail to maximize benefits across the full system. At the 2018 Bay […]

BAY DELTA SCIENCE CONFERENCE: The Delta Conservation Framework: Realizing a Vision for a Sustainable Delta by 2050

In 2016, Department of Fish and Wildlife committed to lead agencies and the Delta stakeholder community in an inclusive planning effort to advance the conservation of the Delta, Yolo Bypass and Suisun Marsh following the state’s pivot away from the Bay Delta Conservation Plan’s comprehensive habitat conservation planning efforts, instead rebranding the effort as the California Water Fix and choosing […]
