The San Francisco Public Utilities Commission voted Tuesday to declare a water shortage emergency amid a crushing drought in the state that threatens water supplies throughout the region, slapping a 5% surcharge on water users in the city. California is in the midst of one of the worst droughts in its history. The drought from 2011- 2017 was so intense that rainy seasons in 2017 and 2018 barely reversed the damage. Mountain snow in 2020 was not enough to fill the state’s reservoirs.
