Gov. Jerry Brown declared the end of California’s five-year drought in April 2017 after a wet winter replenished shrinking reservoirs. But the lingering impact of the drought, especially on groundwater supplies, means some still rely on emergency water tanks while they wait for long-term solutions. This is particularly true in the San Joaquin Valley, where more than 300 domestic well users whose taps have run dry continue to use tanks provided by the state through a program originally slated to end in June.
