Williamson County, TX — July 6, 2025: Severe flooding in Williamson County has left three people missing, prompted multiple rescues, forced widespread evacuations, and triggered a boil water notice affecting thousands of residents. The flooding, caused by days of heavy rain across Central Texas, has overwhelmed the San Gabriel River and surrounding waterways, leading to dangerous conditions and ongoing emergency response.
Williamson County Flooding Overview
Williamson County has experienced one of its most devastating flood events in recent years. Torrential rainfall starting late July 4 caused rapid river swelling and flash floods that inundated homes, roads, and neighborhoods near the San Gabriel River. The National Weather Service issued multiple flood watches and warnings for Williamson County and neighboring areas due to the extreme rainfall and rising water levels.
Local officials declared a state of disaster early Saturday and mobilized emergency crews to assist in rescues and evacuations. Despite ongoing rescue operations, three residents remain missing in Liberty Hill and surrounding areas as floodwaters continue to rise.
Flood Rescues and Search Efforts
Since the flooding began, Williamson County emergency responders have carried out more than 10 water rescues, saving over 25 people trapped in floodwaters. Swift actions by teams from Liberty Hill Fire Department, Leander Water Rescue, and Williamson County Sheriff’s Office prevented further loss of life.
Two of the missing persons were last seen near Hope House in Liberty Hill, where residents were evacuated due to fast-rising water. The third missing individual is also believed to be in the Liberty Hill area. Search and rescue operations are ongoing as crews use boats and drones to survey flooded zones.
Despite the scale of the flooding, no fatalities have been confirmed in Williamson County as of Sunday morning, though the risk remains high. Nearby Travis County has suffered multiple fatalities and dozens of missing persons, highlighting the region-wide impact of the flooding.
Areas and Communities Impacted by Flooding
Several neighborhoods and communities in Williamson County face significant flooding and infrastructure damage:
- Liberty Hill: Site of ongoing search efforts and evacuations. Multiple mobile home parks and residential areas flooded.
- Georgetown: Apartment complexes and RV parks near the San Gabriel River evacuated. Floodwaters damaged local roads and parks.
- Leander: Water rescue operations active, with some homes affected by flash flooding.
- Serenada, Berry Creek, and Stillwater: These subdivisions face boil water advisories and flood-related damages.
Evacuation centers and shelters have been set up, including at East View High School, Georgetown Recreation Center, and several local churches.
Widespread Evacuations Ordered
Williamson County officials issued evacuation orders and warnings for flood-prone areas along the San Gabriel River. Automated reverse-911 calls notified over 1,500 residents to evacuate immediately or prepare to leave as floodwaters rose.
Emergency responders conducted door-to-door checks to assist vulnerable residents, ensuring no one was left behind. Areas with mobile homes and RV parks were prioritized for evacuation due to higher flood risks.
Those evacuated were directed to emergency shelters equipped with food, water, and medical supplies. County Judge Steve Snell emphasized the importance of following evacuation orders:
“Please do not ignore evacuation warnings. Your safety is our top priority.”
Boil Water Notice in Effect for Thousands
Flood damage to water infrastructure in Georgetown and surrounding communities has led to a boil water advisory affecting multiple neighborhoods, including:
- North Old Town / North Addition
- Parkview Estates
- Katy Crossing
- Stillwater
- Crystal Knoll
- Villages of Berry Creek
- Serenada
- Golden Oaks
- Reatta Trails
- Country Club
- Rivery
Residents in these areas are instructed to boil tap water for at least two minutes before using it for drinking, cooking, or hygiene until further notice. The advisory is necessary to prevent waterborne illnesses due to potential contamination caused by floodwaters.
Local officials are testing water quality regularly and will lift the advisory once safe levels are confirmed.

Weather Forecast and Ongoing Flood Risk
The National Weather Service continues to monitor severe weather conditions across Central Texas. The region remains under a Flood Watch through Saturday evening, with forecasts predicting an additional 1 to 3 inches of rainfall, and isolated totals up to 5 inches.
Thunderstorms remain likely, posing ongoing flash flood risks for Williamson, Travis, Burnet, and surrounding counties. Residents are urged to stay informed through official weather channels and avoid flood-prone areas.

Emergency Response and State Support
Williamson County activated its Emergency Operations Center on July 5 to coordinate disaster response and resource deployment. Local, state, and federal agencies are collaborating to provide assistance.
Governor Greg Abbott expanded the disaster declaration to Williamson County, enabling access to additional resources and federal aid. The Lower Colorado River Authority (LCRA) opened floodgates at key dams to manage reservoir levels, warning residents to avoid lakes and rivers due to swift currents and floating debris.

Impact on Residents: Voices from the Flood
Many Williamson County residents are shaken but grateful for the swift emergency response. Ten-year-old Ethan from Georgetown expressed his fear:

“I would have never dreamed it would go that fast. If you wait until the water’s at your feet, it’s too late.”
