California’s Delta Smelt Are Dying: How This Affects The State’s Water

The Delta smelt is such a small and translucent fish that it often disappears from view when it swims in the turbid waters of its home in the Sacramento-San Joaquin Delta.

However, it’s also been disappearing from the Delta entirely.

“The Delta smelt has gone from being one of the more abundant fish in the Delta to being just on the verge of extinction today,” Peter Moyle, an Emeritus Professor of Fish Biology at UC Davis, said.

Trump Administration Surrenders to California, Backs Off On Delta Water Fight

The Trump administration has retreated on a plan to push more water through the Delta this fall after protests from California officials on the harmful impacts on endangered Chinook salmon and other fish.

State officials had been worried that the proposed move, by the U.S. Bureau of Reclamation, also would have meant less water for Southern California cities that rely on supplies pouring out of the Sacramento-San Joaquin Delta.

California Delta A Flash Point For Conflict As Climate Change Unfolds

California’s Sacramento-San Joaquin Delta is vital to water supplies for 25 million people and 4 million acres of farmland. It is linked to the Pacific Ocean via San Francisco Bay, which makes this water supply uniquely vulnerable to sea level rise. Yet understanding sea level rise in the Delta is complicated. The largest estuary on the West Coast of the Americas, it consists of some 70 islands and more than 1,000 miles of levees. It is also fed by California’s two largest rivers, which drain the Sierra Nevada range.
