Fish are going belly up around San Francisco Bay, including in Lake Merritt in Oakland. The water is turning an alarming brown. And people are being warned to limit their exposure to the bay as well. It's all due to a vast algae bloom first spotted last month near Alameda and spreading fast. What's behind the bloom? Is it related to climate change or the drought? When will it go away? Host Demian Bulwa is joined by Dave Senn of the San Francisco Estuary Institute and Keith Bouma-Gregson of the U.S. Geological Survey. | Unlimited Chronicle access: sfchronicle.com/pod
