When Maria Regalado Garcia tried to wash the dishes in her California home one recent morning, only a trickle of water emerged from the kitchen faucet. Other taps in her Tooleville house in rural Tulare County ran similarly dry.

The lack of water meant Garcia, 85, couldn’t brush her teeth properly or fill a swamp cooler that pumps out chilled air — a necessity with temperatures topping 100 degrees in her central California town. So Garcia fled to her granddaughter‘s home in Exeter, a few minutes away, to have a place cool enough to sleep.
