BAY DELTA SCIENCE CONFERENCE: Harvest, Hatchery Returns, and Straying of Salmon Released at Bay and Delta sites during California’s Drought

Best of the Notebook, Science Features

The U.S. Fish and Wildlife Service’s Coleman National Fish Hatchery is the largest salmon hatchery in California, annually producing 12 million fall Chinook Salmon smolts that substantially contribute to California’s ocean and inland fisheries. Standard practice at Coleman NFH is to release smolts on-site into Battle Creek; however, during the severe drought of 2014 and 2015, degraded water quality throughout […]

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

Best of the Notebook, Conferences and Seminars, Science Features

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 […]

DR. JEFF MOUNT: Making groundwater a centerpiece of managing the droughts of the future

Best of the Notebook, Conferences and Seminars

Four essential policy reforms are needed to reduce the social, economic, and environmental costs of future droughts, says Dr. Mount California’s climate is changing. Hotter temperatures, a shrinking snowpack, shorter and more intense wet seasons, rising sea level, and more volatile precipitation—with wetter wet years and drier dry years—are stressing the state’s water management system. Recent climate projections indicate that […]
