Cover - EstuaryNewsMar2017-v9This issue of ESTUARY News magazine debuts a new guide to how to repair and renew the Delta and examines stresses on Delta species, especially pesticides. Two stories explore innovations in flood control and restoration, ranging from online tools to custom equipment. Others cover what scientists do to collect data during a big storm and what they think will happen to Central Valley waterbirds based on climate change models. A final story describes key steps in the creation of the Bay’s new restoration authority.

Pesticides make salmon more susceptible to pathogens, as do rising temperatures, highlighting the importance of tracking multiple stressors on fish and other aquatic life in the Delta. READ ON
