What the reports say
Written by National Weather Service staff at the time of the event · public domain
Heavy rain caused an extensive rise in area creeks and rivers, pushing the Llano River to near 40 feet at the USGS river gauge in Llano. This is the 2nd highest ever recorded height on the river in the city of Llano. Flow peaked out about 285,000 CFS around 730 AM that morning nearly coming up to the level of the Highway 16 (Ford St.) bridge in town. Several homes were flooded along the river with damage to the area parks as well. A 58 year old woman lost her life in her vehicle as she was trying to get to work in town near West Sandstone and Flag Street. Time when she entered the water is unknown but is estimated around 5 AM that morning. Phone and internet service went down as the high water flow washed away phone lines underneath the Llano River Bridge. Damage in the city of Llano will likely surpass 1 million dollars.
Rainfall in Llano County began near 0300 CST and continued into the mid morning. By 6 am, accumulations were averaging 2 inches over the north part of the county and 4 inches over the south part.

Flash flooding developed just before sunrise, with the worst problems across the southeastern part of the county, from Kingsland to Sunrise Beach. Numerous cars swept into flooded creeks along low water crossings in the Kingsland area. A 2-year old girl was pulled out of a flash flood near her home in Kingsland. She later died at a hospital.
Heavy rain overnight produced flash flooding that washed away the FM 2900 bridge across the Llano River in Kingsland. A body was recovered near Kingsland and it was determined that this fatality came from a flood in the city of Junction the previous week. Damage to the bridge is estimated at 20 million dollars.
