California’s biggest rivers converge in the Sacramento-San Joaquin River Delta, the waterways and wetlands forming an ecosystem where fresh water meets salt water from San Francisco Bay, and where native fish historically flourished. Every few years, dozens of scientists examine the environmental health of the estuary in a report card that considers water flows, wildlife and habitat, as well as other factors. Their latest shows the bay is mostly in fair condition and stable, but the Delta is “mostly in poor condition and declining.” According to the State of Our Estuary report, less fresh water has been flowing through the Delta in recent years, which creates “chronic artificial drought conditions” and harms fish.
