Los Angeles saw its eighth wettest season in 145 years last winter. The torrential downpours did more than fill aquifers, shrink water waste complaints and ease drought concerns—they also led to the biggest cutbacks in regional residential water use in four years.

The average customer of the Los Angeles Department of Water and Power used 59.5 gallons per day from Jan. 1–May 31, according to publicly available water use and conservation data from the California State Water Resources Control Board.
