Which reservoirs are at the highest risk of extreme weather this year?

This year is already shaping up to be the most extreme on record, and California is no exception.

The state is expected to be hit with an unprecedented drought in 2019, as well as record temperatures that have left reservoirs at record levels.

In the first three months of 2018, a record 3.6 billion people were without water, the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said, which is a record high number.
