The Sacramento San Joaquin delta supplies drinking water for more than half of California. Just inland from the San Francisco bay, this patchwork of levees, farmland and waterways is threatened by rising seawater.  But people who live there say the state's plan to take freshwater from north of the delta will only make things worse

A new study released this week by the San Francisco Estuary Institute and the California Department of Fish and Game aims to turn back the clock and learn how the Sacramento-San Joaquin Delta used to work - over 150 years ago.

It's part of an effort to allow scientists to better understand how to restore the Delta, by examining how the massive freshwater estuary functioned, before the gold rush and agriculture transformed the region with levees, shipping channels and dredging. 

Last week, California Governor Jerry Brown declared that the wet winter has officially put an end to the state’s drought. But with the annual April 1 Sierra snowpack at 165 percent of average, does that mean California’s water woes are behind it, or are just getting started. This week on Quality of Life, UC Merced hydrologist Dr. Roger C. Bales tells us about the science of measuring snow, and what global warming might mean for the our water supply.
