For the first time in 11 years, the Sacramento River floodgates were opened Monday. Officials released water from the Folsom Lake reservoir and several others to prevent flooding. An impending storm is expected to bring 7 feet of snow in higher elevations to the state. By the end of the week, the total for the year could already be up to 20 feet. “We haven’t seen an event of this magnitude in at least a decade,” state climatologist Mike Anderson said to the Los Angeles Times.
