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 water that flows from the Central Valley to San Francisco Bay. But are these assertions true? Are Delta smelt really responsible for as much as they get blamed for?
The Bay Institute studied water management practices and constraints that affect the flow of water into and through the San Francisco Bay and the Delta estuary, which is home to six imperiled fish species and water export facilities owned by the state and federal governments that serve millions of people and large expanses of agricultural land.
Using several public data sources, The Bay Institute analyzed the long‐term trend in the net effect on Delta outflow of water diversions in the estuary’s Central Valley watershed, and the frequency and magnitude of specific regulatory and infrastructural constraints on the two water export facilities.
Greg Reis, a scientist with the Bay Institute, as well as an Information & Restoration Specialist at Mono Lake Committee, gave a presentation at the 2018 Bay Delta Science Conference to discuss the results.
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 a preliminary investigation of the potential regional impacts of sea level rise on coastal aquifers of the San Francisco Bay Area. Some of California’s densest and most economically valuable development is built around the Bay on unconsolidated sediment, with an already high water table that will be lifted higher as sea level rises.
At the 2018 Bay Delta Science Conference, Ellen Plane from UC Berkeley and Abby Mohan with Silvestrum Climate Associates discussed their research.
