What the reports say
Written by National Weather Service staff at the time of the event · public domain
At 9:26 p.m. CDT Saturday, March 21, the Gillespie County Sheriff's Office and Fredericksburg Fire EMS responded to a report of a vehicle that had been swept away by fast-moving water at the Pedernales River crossing on Alfred Petsch Road. Upon arrival, it was determined that there had been four occupants in a vehicle, ages 36, 15, 14, and 13. Three people made it out of the vehicle safely but the 14-year-old was missing. Shortly after 11 p.m. CDT, the girl was located in the water about a mile from where the vehicle was. Emergency personnel began CPR and transported her to Hill Country Memorial Hospital where she was later pronounced dead.
Continued periods of showers and thunderstorms through the nighttime hours produced general 3 to 4 inch rain amounts over much of Gillespie County. Amounts as high as 6 inches were reported near Willow City and also southwest of Fredericksburg. Most rural roads were closed through both the late evening and in the morning hours due to high water. A young man was swept away in his vehicle at a low water crossing on Goehmann Lane near Fredericksburg about 2100 CST.
The extremely heavy rainfall associated with the remains of Tropical Storm Erin moved into Gillespie County in the late afternoon, producing general 3 to 5 inch amounts. Highest were 9 inches at Cain City just south of Fredericksburg. Most roads in the southern and western part of the county were closed due to flooding. High water rescues were made on Bear Creek Road in the county and on East College Street and Goehmann Lane in Fredericksburg. US290 was blocked by the Pedernales River by early Friday morning and the LBJ Ranch was closed to visitors all day on Friday.
