The Santa Clara Valley Water District, which is the main wholesale water provider in Santa Clara County, on June 9 declared a drought emergency and called on all residents to reduce water use 15% from 2019 levels to preserve supplies.

In August, the most recent month for which data is available, countywide water use dropped by 9%. That was an improvement from a 6% drop in July, but still is significantly under the goal.

Here is the percentage change in water use between August 2019 and August 2021 at the 13 cities and private water companies the Santa Clara Valley Water District serves.
