Emergency crews say more than 85 people checked in at evacuation centers set up at Dayton High School and Dayton Valley Senior Center.
The folks most affected by the evacuations were the senior citizens at a nearby retirement home.
After taking refuge at the Dayton Valley Senior Center for an hour and a-half, 99-year-old Ethal Shibler was among the dozens of residents able to go back home.
Buses took the group to the Dayton Parkview adult home. Ethal says she has never lived through such an event.
"They expected it to explode at anytime. That's how I understand it," she says.
According to to workers, crews were installing a new gas line when the main line was hit. Witnesses say around 8 a.m., a back hoe sliced through the line releasing a plume of natural gas into the air.
That's when Southwest Gas employees called for help.
Crews came from all over Lyon County and set up a command post at Flowerly Avenue and Rose Peak. Minutes later, homes in a one mile radius around the incident were evacuated.
Nancy Roebuck, the owner of Dayton Parkview adult home, says her main concern was getting her 52 residents to safety. "We just started hoofing them over as fast as we could get them," she says.
And before lunch time her residents were back at home ready to eat.
"You're always glad to get back and everything is okay."
At this hour all residents are back at home and gas has been restored.
