A darker shade of blue means that the measure is higher than the historical average. The bigger the diamond, the larger the reservoir’s capacity. To interact with the map above, scroll and click on one of the reservoirs, represented by a diamond. The San Luis Reservoir, for example, which serves millions of people from Silicon Valley to San Diego, is now effectively full, at 99% of capacity.

Drought Monitor, show that this year’s rainy season washed away drought conditions in all of the Bay Area and most of California. “For most purposes, the drought is over,” said Jay Lund, a California water expert and professor of Civil and Environmental Engineering at UC Davis. Just how “over” is the drought, and how unusual has this season of rain really been? Here are seven charts to help with the answers.
