Wells as deep as 900 feet have gone dry in Tuolumne County.
This week and next, the Tuolumne County Office of Emergency Services is holding six workshops so people can sign up to have water delivered at no cost in most cases.
Emergency Services Coordinator Tracie Riggs says many families have already been helped.
"We have about 85 tanks that have been placed and that affects a little over 300 homes," says Riggs. "Each tank holds 2,500 gallons and we are rationing out 50 gallons of water per person per day."
Riggs says the workshops can help people get a tank in as little five business days.
"Normally our Environmental Health responds within 24 hours if not less and that means someone showing up on your doorstep."
Wells in Columbia, Jamestown, and more recently, Groveland have failed.
