WILLIAMSON COUNTY, Texas (KXAN) — Leaders in Williamson County said a wildfire that burned almost 500 acres near Liberty Hill is fully contained as of Thursday morning.

Previously, during a news conference Monday afternoon, County Judge Bill Gravell said the San Gabriel Fire, which sparked Saturday close to Tower Road, was 90% contained. The cause of the fire remains under investigation. The fire was estimated to have burned 451 acres, down from 500 earlier due to improved GPS mapping of the fire, officials said.

Local firefighters warned people may still see smoke rising from the area for the next couple of days, but they urged neighbors not to worry, because crews will remain on site to monitor and put out any flareups.

Crews are also asking people to carefully watch what they’re doing outdoors, because any spark could quickly ignite the “critically dry” vegetation, grasses and trees. A burn ban remains in effect for Williamson County, the judge noted.

The fire forced evacuations of 200 homes in the area Saturday, but residents were allowed to return by Saturday night, the county said. Santa Rita Middle School was opened as a shelter for those who did evacuate earlier in the day.

Gravell said if the wind blew from another direction Saturday, the extent of the damage would have been much worse.

Additionally, Lake Georgetown and its surrounding trails are closed to visitors until further notice.

So far, there are no reports of deaths or any structures that have been damaged.
