“The rule for releasing water is rigid and dates to the 1950s,” says Jay Jasperse of the Sonoma County Water Agency. Near the end of 2012, the US Army Corps of Engineers released 28,000 acre-feet of water from Lake Mendocino. Then followed 14 of the driest months on record. The key to managing the drought and deluge cycle of California lies in a better understanding of atmospheric rivers, intense winter storms that transport water from the tropics to the West Coast. Over the last decade California has pumped more than $40 million into the statewide network that tracks these rivers, giving lead times of up to a week. Researchers continue to work to push the boundaries of what’s possible.

Over time, the median actual flow to San Francisco Bay in the ecologically critical winter and spring months has declined to less than half of the unimpaired runoff. This bar chart divides actual inflow (the amount that actually made it to the Bay) and unimpaired runoff (the inflow to the Bay that would occur if there were no dams or diversions) into quintiles from wettest to dry, and marks years drier than 2015 (roughly, the driest 2% of years) as “super-critically dry” years. Over the last 54 years, “super-critically dry” runoff conditions in the Bay’s watershed occurred naturally only once, in 1977, but the Estuary received runoff volumes in the super-critical range in 22 years, or 40% of the time. Overall, flow volumes characteristic of the driest 20% of years now occur more than half the time as a result of storage and diversion of runoff for consumptive uses.

Defining Unimpaired Flows

For the second time in four years, a proposal for a voluntary agreement between agencies and water contractors on flows into and through the Delta from the San Joaquin and Sacramento rivers and their tributaries is wending its way through the State Water Resources Control Board. The proposal, which would...
