Outlook 2018: The Biggest Water Topics In The West This Year

For the next few months much of the talk around water issues in California and the rest of the Western United States will be about how much precipitation falls, the water content of the snowpack and how temperatures will impact runoff in the spring.

Last year’s devastating floods and fires in California combined with hurricanes and other natural disasters to wreak unprecedented financial damage on the United States, the federal government reported Monday.

A Dense Blob Has Kept California Weather Dry. Here’s How It Works

Think of it as a dense blob of air. When it parks itself over the Pacific Ocean, it can act like a wall – and prevent rain and snow from reaching Northern California. When meteorologists say a “high pressure system” or a “ridiculously resilient ridge” is keeping the West unseasonably dry, this is what they mean.

A tiny fish caught in California’s tug of war over water has become harder to find than ever, a state survey found, despite a very wet winter last year that had raised hopes for a bounce back after five years of drought. Environmentalists say the record-low fall survey for the Delta smelt bolsters the case for protecting salmon and other wild fish with sharper limits on water exported from the Sacramento San Joaquin River Delta to San Joaquin Valley farms and many cities in California
