Several months ago, Mike Moran of the Delta’s Big Break Regional Park got a call about a cluster of unusual looking eggs. “We thought we might be looking at this channeled apple snail thing,” he says. Native to the Amazon and Plata river basins of South America, the snails are now officially identified and documented in northern California by the USGS. “What we are worried about is the snail’s voracious appetite for aquatic plants,” says Moran. How the snails ended up in California is still unknown, but the potential ecological impacts on the Delta are concerning.

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.
